The largest of muscles that attach to the upper surface of the greater horns are the hyoglossus and the middle pharyngeal constrictor, which extend along the whole length of the horns; the digastric muscle and stylohyoid muscle have small insertions in front of these near the junction of the body with the horns. The apex of each horn gives attachment to the stylohyoid ligament; the chondroglossus rises from the medial side of the base. Unlike other bones within the skeleton, the hyoid does not feature any major points of articulation (joints) with other bones. Structure and Functions of Hyoid Bone. The hyoid bone is a very special bone in the human head which is unique in that it is not attached to any other bones in the body; rather, it is supported by a network of muscles and ligaments, which trap it like a fly in amber directly below the tongue. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. The upper surface of the greater horns are rough and close to its lateral border, and facilitates muscular attachment. The hyoid bone is a horseshoe shaped bone found in the neck. The lesser cornua are small conical projections oriented upwards. U-shaped non-articulate bone that is suspended from the temporal bone styloid process. The hyoid bone is important to a number of physiological functions, including breathing, swallowing and speech. Anatomy and Function of the Equine Hyoid Apparatus - The hyoid bone and its relationship with the fascia, and the temporomandibular (TMJ) joint between the temporal and mandible bone, are areas of fascination for me. The hyoid bone of a gecko with attached tracheal rings, Hyoid bones of various birds in the Natural History Museum, Vienna, In veterinary anatomy, the term hyoid apparatus is the collective term used to refer to the bones of the tongue — a pair of stylohyoidea, a pair of thyrohyoidea, and unpaired basihyoideum[20] — and associated, upper-gular connective tissues. © 2005-2021 Healthline Media a Red Ventures Company. [citation needed] The lesser horns are derived from the second pharyngeal arch also called the hyoid arch. The hyoid bone is small, and it functions as an attachment point for many muscles involved in swallowing, jaw movements, and respiration. Blood is supplied to the hyoid bone via the lingual artery, which runs down from the tongue to the greater horns of the bone. It allows a wider range of tongue, pharyngeal and laryngeal movements by bracing these structures alongside each other in order to produce variation. The hyoid bone is only distantly articulated to other bones by muscles or ligaments. Due to its position, the hyoid bone is not easily susceptible to fracture. A mechanistic involvement of the hyoid bone in OSA is supported by numerous studies demonstrating that a more inferiorly positioned hyoid bone is strongly associated with the presence and severity of the disorder. Purpose and Function Supports the tongue, providing attachment sites for muscles of the tongue, neck, and pharynx. The bone has a central body (forming the center of the “U”) with two smaller protruding structures on the superior surface (lesser horns) and two larger bony protrusions from the body (greater horns). [18] A surgical procedure that aims to potentially increase and improve the airway is called hyoid suspension. While the hyoid bone provides protection to these organs, it can be fractured if exposed to excessive forces. The suprahyoid branch of the lingual artery runs along the upper border of the hyoid bone and supplies blood to the attached muscles. [8] The discovery of a modern-looking hyoid bone of a Neanderthal man in the Kebara Cave in Israel led its discoverers to argue that the Neanderthals had a descended larynx, and thus human-like speech capabilities. In early life the outer borders of the body are connected to the greater horns by synchondroses; after middle life usually by bony union. The body of the hyoid bone is the central part of the hyoid bone. Shoshani J., Marchant G.H. The extensor…. It helps the tongue movement, such as speaking or swallowing. The central basihyoid bone supports the lingual process, to which the tongue is attached. It is necessary when eating (chewing and swallowing) and speaking. The hyoid bone is an intermediary between the skull and postcranial skeleton. This bone also provides a place of attachment for many muscles associated with the mouth’s floor, as well as the larynx (voice box), pharynx (throat), and epiglottis (flap of tissue located at the top of the larynx). It helps elevate the larynx and support the tongue whenever a person swallows or talks. See more. 2. any distinct piece of the skeleton of the body. [citation needed]. Amphibians and reptiles may have many cornua, while mammals (including humans) have two pairs, and birds only one. It is also at the base of the mandible, or lower jawbone. These four muscles have different actions, but in general assist in elevating the hyoid bone and widening the esophagus during swallowing.When the two bellies of the digastric contract, they pull upward on the hyoid bone; but if the hyoid is fixed from below, the digastric assists in extreme opening of the mouth such as yawning or taking a large bite of an apple. The hyoid bone is a U-shaped bone that is held in place by the strap muscles of the anterior triangle of the neck. The hyoid is a "horseshoe-shaped" bone that serves as a structural anchor in the mid-neck.It is the only bone in the human body that does not directly articulate with another bone (other than sesamoids).). Swallowing function may be impaired due to problems such as stroke, neck injuries, or jaw and neck cancers. Hyoid apparatus: a little-known complex of bones and its "contribution" to proboscidean evolution, "Upper airway collapsibility is associated with obesity and hyoid position", "Development and validation of a computational finite element model of the rabbit upper airway: simulations of mandibular advancement and tracheal displacement", "Hyoid Apparatus - Definition of Hyoid Apparatus", https://en.wikipedia.org/w/index.php?title=Hyoid_bone&oldid=998789503, Wikipedia articles incorporating text from the 20th edition of Gray's Anatomy (1918), Articles with unsourced statements from January 2014, Creative Commons Attribution-ShareAlike License. Ossification commences in the greater cornua toward the end of fetal development, in the hyoid body shortly afterward, and in the lesser cornua during the first or second year after birth. It anchors the hyoglossus muscles for creating a depression on the tongue so as to enlarge the oral cavity. It allows a wider range of tongue, pharyngeal and laryngeal movements by bracing these structures alongside each other in order to produce variation. The greater horns project backward from the outer borders of the body; they are flattened from above downward and taper to their end, which is a bony tubercle connecting to the lateral thyrohyoid ligament. Last medically reviewed on January 20, 2018, The adductor hallucis is a two-headed muscle that is responsible for flexing and contracting the big toe, and reinforcing the arch of the foot. Functions of the hyoid bone. supports the tongue, providing attachment sites for muscles of the tongue, neck, and pharynx. The hyoid bone is liable for an appendage of the root of the tongue. (2001.) In many animals, it also incorporates elements of other gill arches, and has a correspondingly greater number of cornua. The hyoid bone (Lingual Bone) is unique in that it is the only bone of the body that does not articulate with any other bone. hyoid bone. To the medial border the thyrohyoid membrane is attached, while the anterior half of the lateral border gives insertion to the thyrohyoid muscle. The primary role of the bone is to support the weight of the tongue, allowing people to articulate words while speaking, and enabling the production of a wide range of vocalizations. 5. It is necessary when eating (chewing and swallowing) and speaking. [22], This article incorporates text in the public domain from page 177 of the 20th edition of Gray's Anatomy (1918), American heritage dictionary for English language. This started last week, where I will go to unconsciously swallow saliva and I feel a popping sensation from the ligaments/cartilage around the left side of my hyoid. [6] Its descent in living creatures is not unique to Homo sapiens,[7] and does not allow the production of a wide range of sounds: with a lower larynx, men do not produce a wider range of sounds than women and 2-year-old babies. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Hyoid Bone Function. It isn’t directly attached to any other bone. Exercises for swallowing function m… Hyoid bone function is structural – it holds up the tongue from below and keeps the larynx in place from above. The hyoid bone is present in many mammals. Its descent in living creatures is not unique to Homo sapiens, and does not allow the production of a wide range of sounds: with a lower larynx, men do not produce a wider range of sounds than women and 2-year-old babies. Quiz: What is Anatomy and Physiology? You can feel your own hyoid bone here, and you can move it from side to side. The hyoid bone is the only bone that has no direct contact with any other bone in the human body (see Figure 1). It lifts larynx during deglutition. The hyoid bone can be divided into three component parts: the body of the hyoid, the greater cornua, and the lesser cornua. The hyoid bone forms a movable base for the tongue and its varied movements and is held in position by a large number of muscles. The greater and lesser horns (Latin: cornua) are two sections of bone that project from each side of the hyoid. hyoid bone function. Your speech therapist may perform specific exercises to help you swallow better, and these may involve getting familiar with your hyoid bone. Previous Hyoid Bone. The hyoid bone serves as the attachment for the tongue and pharynx, and is made up of paired stylohyoid, epihyoid, ceratohyoid and thyrohyoid bones, with a central basihyoid bone. Its name is derived from Greek hyoeides 'shaped like the letter upsilon (υ)'.[4][5]. Hyoid bone function is structural – it holds up the tongue from below and keeps the larynx in place from above. Fitch, Tecumseh W., The evolution of speech: a comparative review, in: Trends in Cognitive Sciences, Vol. Arsenburg, B. et al., A reappraisal of the anatomical basis for speech in middle Paleolithic hominids, in: American Journal of Physiological Anthropology 83 (1990), pp. The hyoid is ossified from six centers: two for the body, and one for each cornu. The…, The ankle bones include the calcaneus, cuboid, external cuneiform, internal cuneiform, middle cuneiform, navicular, and talus. [21] In humans, the single hyoid bone is an equivalent of the hyoid apparatus. Until middle age the connection between the body and greater cornu is fibrous. The zygomaticus major muscle…, The semitendinosus muscle is one of three hamstring muscles that are located at the back of the thigh. It's suspended just beneath the mandible. The hyoid bone is located between the chin and the thyroid cartilage. The lingual bone keeps the airway open between the oropharynx and tracheal rings and, therefore, plays a role in respiration. The function of the hyoid is to provide an anchor point for the muscles of the tongue and for those in the upper part of the front of the neck. The omohyoid is made up of two bellies, the superior and the inferior, joined through an inter-muscular tendon (a flexible and fibrous tissue). Next Vertebral Column. Hyoid bone randomly popping, will neck stretches alleviate this? It is one of the suprahyoid muscles. Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. The hyoid bone is located between the chin and the thyroid cartilage. It helps its movement for actions such as speaking or swallowing. hyoid bone: [ bōn ] 1. the hard, rigid form of connective tissue constituting most of the skeleton of vertebrates, composed chiefly of calcium salts. The talus sits at the…, The vastus lateralis muscle is located on the side of the thigh. In a suspected case of murder or physical abuse, a fractured hyoid strongly indicates throttling or strangulation in an adult. The stylohyoid muscle is a slender muscle, lying anterior and superior of the posterior belly of the digastric muscle. Our website services, content, and products are for informational purposes only. The second pharyngeal arch, also called the hyoid arch, gives rise to the lesser cornu of the hyoid and the upper part of the body of the hyoid. Moreover, the larynx position of Neanderthals was not a handicap to producing speech sounds. It shares this muscle's innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the tongue.Its origin is the styloid process of the temporal bone.It inserts on the body of the hyoid. [11][12], A large number of muscles attach to the hyoid:[13]. hyoid bone: [noun] a U-shaped bone or complex of bones that is situated between the base of the tongue and the larynx and that supports the tongue, the larynx, and their muscles — called also#R##N# hyoid. The lesser horns are situated in the line of the transverse ridge on the body and appear to be continuations of it. The portion of the vertical ridge above the transverse line is present in a majority of specimens, but the lower portion is evident only in rare cases. At rest, it lies at the level of the base of the mandible in the front and the third cervical vertebra (C3) behind. Not only attachment, hyoid bone also gives shield to the attached muscles.Ossification of hyoid bone initiate speech to the human child, as it provides support to tongue. The greater horns derive from the third pharyngeal arch. The body of the hyoid is centrally located, while the cornua are on both sides. These sections are the occipi… The hyoid bone plays an important role in the occurrence of speech in humans. [9] However, other researchers have claimed that the morphology of the hyoid is not indicative of the larynx's position. The hyoid bone is involved in several functions of the throat, including breathing, swallowing, and talking. See anatomic Table of Bones in the Appendices for regional and alphabetical listings of bones, and see color plates 1 and 2. [16][17] Movement of the hyoid bone is also thought to be important in modifying upper airway properties, which was recently demonstrated in computer model simulations. The hyoid bone consists of three separate parts – the body, and the left and right greater and lesser cornu (horns) – which fuse in early adulthood. choking). [citation needed], The lesser horns are two small, conical eminences, attached by their bases to the angles of junction between the body and greater horns of the hyoid bone. In birds, and some reptiles, the body of the hyoid is greatly extended forward, creating a solid bony support for the tongue. The hyoid bone is a slender, U-shaped bone. The hyoid bone has a body and two pairs of horns, each of which is also called a cornu, the Latin word for “horn.” Functions Of The Hyoid Bone. Healthline Media does not provide medical advice, diagnosis, or treatment. Hyoid Bone Functions. The hyoid bone is present in many mammals. If that occurs, working with a specialist like a speech pathologist may be useful. The primary function of the hyoid bone is to serve as an attachment structure for the tongue. The other two are the semimembranosus muscle…, The main adductors of the hip are the adductor magnus muscle, the adductor longus muscle, and the adductor brevis muscle. … It anchors the hyoglossus muscles for forming a hole in the tongue so as to expand the oral cavity. Hyoid bone, U-shaped bone situated at the root of the tongue in the front of the neck and between the lower jaw and the largest cartilage of the larynx, or voice box. 137–146. The hyoid bone is derived from the lower half of the second gill arch in fish, which separates the first gill slit from the spiracle, and is often called the hyoid arch. All rights reserved. It is a U-shaped structure lying between the root of the tongue and mandible and the thyroid cartilage. The hyoid bone is a horseshoe-shaped bone in the front, middle of the neck, located between the mandible (lower jaw) and the larynx (voice box). It is also thought to play a key role in keeping the upper airway open during sleep,[14][15] and as such, the development and treatment of obstructive sleep apnea (OSA; characterized by repetitive collapse of the upper airway during sleep). consists of a horizontal body and paired projections called the lesser horns and the greater horns muscles and ligaments attach to the body and these paired projections. The hyoid bone is located in the neck and can be palpated immediately above the thyroid cartilage. The oral muscular structures such larynx, pharynx and epiglottis are attached to the hyoid bone and also perform specific functions which include voice generation and deglutition. I am a life-long bruxer but this is the first time I've had an issue with the hyoid. Hyoid definition, noting or pertaining to a U-shaped bone at the root of the tongue in humans, or a corresponding bone or collection of bones in animals. 4, No. The greater cornua extends backwards from the body of the hyoid. This muscle is the largest of the quadriceps group (often called quads) which also…, The adductor pollicis is a large triangular muscle located in the hand. The hyoid bone (lingual bone or tongue-bone) (/ˈhaɪɔɪd/[2][3]) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. The lingual bone keeps the airway open between the oropharynx and tracheal rings and, therefore, plays a role in respiration. Moreover, the larynx position of Neanderthals was not a handicap to producing speech sounds. Hyoid Bone Function. Function. It is also at the base of the mandible, or lower jawbone. Hyoid bone can be divided into three component parts: the body of the hyoid, the greater cornua, and the lesser cornua. Since cornua come in pairs, the greater and lesser cornua can be differentiated into left and right sections. 7, July 2000 (. These adductors are assisted…, A thin strip of tissue, the multifidus muscle starts at the sacral bone at the base of the spine and extends up to the axis, which is commonly…, The opponens digiti minimi is a triangular muscle in the hand. The hyoid bone is responsible for attachment of the root of the tongue. Typically, a broken hyoid results from forced strangulation (i.e. The cartilage of the third pharyngeal arch forms the greater cornu of the hyoid and the lower portion of the body of the hyoid. At the front, the body is convex and directed forward and upward. The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns. Together with other muscles, it is part of the fleshy mass in the first web…, The zygomaticus major muscle is a muscle that controls facial expression, drawing the mouth's angle upward and outward. It is supported by the muscles of the neck and in turn supports the root of the tongue. It is a place of convergence of multiple small neck muscles that permit the pharyngeal phase of swallowing. It combines skeletal elements of the second and the third pharyngeal arches associated with the gills of primitive fish. The hyoid bone is a small U-shaped mobile bone (Figure 1) oriented in the horizontal plane just superior to the larynx, where it can be palpated and moved from side to side. The hyoid bone resembles an archer’s bow. Called also os . They are connected to the body of the bone by fibrous tissue, and occasionally to the greater horns by distinct diarthrodial joints, which usually persist throughout life, but occasionally become ankylosed. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The inferior belly of the muscle divides the neck's posterior triangle, an area at the side of the neck, into two sections. Susan McLaughlin, Physical Therapist describes how to release the muscles that attach to the hyoid bone.

Its name is derived from the Greek word … [19] The howler monkey Alouatta has a pneumatized hyoid bone, one of the few cases of postcranial pneumatization of bones outside Saurischia. [10] It is necessary to take into consideration the skull base, the mandible and the cervical vertebrae and a cranial reference plane. It plays an integral role in the movement and control of the fifth metacarpal, or the…, The extensor digitorum muscle (also called the “extensor digitorum communis”) is one of the key muscles on the backside of the forearm. [citation needed]. However, this is not necessarily the case in children and adolescents, where the hyoid bone is still flexible as ossification is yet to be completed. It functions to protect the essophagus and facilitates a wide range of movements involved in speaking and swallowing. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves. This tendon passes obliquely (in a slanted direction) through the lateral cervical area (the side of the neck), supported by a connective tissue that prevents the internal jugular vein from being squeezed under severe pressure.
