The Mentohyoideus muscle passes from the body of hyoid bone to chin. The Sternohyoideus ( Sternohyoid muscle) is a thin, narrow muscle, which arises from the posterior surface of the medial end of the clavicle, the posterior sternoclavicular ligament, and the upper and posterior part of the manubrium sterni. http://www.wikimd.org/index.php?title=The_Supra-_and_Infrahyoid_Muscles&printable=yes      Kurt Edward Kruckeberg The stylohyoid muscle originates at the styloid process and inserts at the hyoid bone. The omohyoid muscle originates at the scapula and inserts at the hyoid bone. Sub-hyoid muscles are categorized as such because they generally lie inferiorly of the hyoid bone. http://ucsu.colorado.edu/~kruckebe/PedI.htm      Neck muscles It assists the mylohyoid and geniohyoid muscles in moving the hyoid bone and the tongue upward and forward and then upward and backward during the process of swallowing. The muscle pulls the hyoid bone down, as in swallowing, and assists in flexion of the head and neck. It assists the geniohyoid, which lies just beneath the mylohyoid muscle, and the digastric muscles in moving the hyoid bone and the tongue upward and forward and then upward and backward during the process of swallowing. http://www.american.edu/adonahue/m7neck.htm      June Issue.indd The hyoid bone would appear to provide a readily identifiable (radiographic) anatomic landmark, whose position is the result of a multifactorial postural system, which is closely aligned with maintaining respiratory function. In the first instance, the relationships existing between AHI and the measurements pertaining to the position of the hyoid bone (H) relative to the third cervical vertebra and to the anterior cranial base (S) were analysed to determine the Spearman’s correlation coefficients. These results suggest that the inter-subject variability in hyoid bone position as related to the point S on the anterior cranial base, which one might attribute to postural differences and to expected differences in craniofacial dimensions (size), may be less significant than expected. http://www.rcsed.ac.uk/journal/svol2%5F3/2030004.html      Dept of Anth: Hyoid Page The hyoid is a single small "U" shaped bone in the adult which does not articulate with any other bone. The hyoid does not articulate with (i.e., touch) any other bones. It is suspended from the styloid process of each temporal bone by means of the stylohyoid ligaments. http://www.csuchico.edu/anth/Module/hyoid.html      RTOG - Table Neck CTV Caudal edge of the body of hyoid bone Cranial edge of the body of hyoid bone Caudal edge of lateral process of C1 Caudal edge of the body of hyoid bone http://www.rtog.org/hnatlas/tableneck.html      Behaviors of hypoglossal hyoid motoneurons in laryngeal and vestibular reflexes and in deglutition and emesis -- Umezaki et al. 274 (4): 950 -- AJP - Regulatory, Integrative and Comparative Physiology The TH muscle nerve was dissected near the hyoid bone; the GH muscle nerve was dissected beneath the mylohyoid muscle as a branch Behaviors of hypoglossal hyoid motoneurons in laryngeal and vestibular reflexes and in deglutition and emesis Behaviors of hypoglossal hyoid motoneurons in laryngeal and vestibular reflexes and in deglutition and emesis -- Umezaki et al. http://ajpregu.physiology.org/cgi/content/full/274/4/R950      Tongue Suspension and Hyoid Suspension Electrocautery is used to detach the infrahyoid muscles from the body of the hyoid bone between the lesser cornuae. The polypropylene suture is passed around both sides of the hyoid bone in a figure of eight configuration. One end of the polypropylane suture is then loaded into a Mayo needle and is passed through the suprahyoid muscles using a full thickness bite of the tissue. http://www.influ-ent.com/KrespiAbstract.htm      Chapter 13 On the Bone Resembling the Greek Upsilon stylohyoideum ] attached to the hyoid bone and the styloid process. The hyoid bone is therefore neither free-floating nor contiguous to any bone, as the connection of the superior sides to the temporal bones shows. These ossicles, attached to the superior sides of the hyoid bone, are not always observed in an equal number, but usually three or four are seen on each side. http://vesalius.northwestern.edu/chapters/FA.1.13.html      The Evolution of the Woodpecker's Tongue The primary connections between the woodpecker's hyoid apparatus and the rest of its body are muscles and ligaments which attach the hyoid to the mandible (jawbone), cartilage of the throat, and base (not top) of the skull- the same configuration found in all other birds. "There is a very curious gradation in the degree of elongation of the horns of the hyoid bone in the different American Woodpeckers, some of which consequently have the power of thrusting out their tongue to a much greater extent than others. Attachments of Mbm to hyoid horns and mandible (jawbone) are shown in purple. http://www.talkorigins.org/faqs/woodpecker/woodpecker.html      Tongue base surgery The hyoid bone is important in determining tongue position, and the anterior advancement of the hyoid bone can enlarge the airway at the tongue base level. The position of the tongue is largely determined by the position of two bones: the lower jaw (or mandible) and the hyoid bone. The decision as to which procedure(s) should be offered to any given patient is determined by careful examination of the patient’s airway, with particular attention to the size, shape, and relationship of the jaws, size and position of the tongue, position of the hyoid, and expectations of the patient. http://www.hnsaonline.com/tongue_base_surgery.htm      The Location of Hyoid Fractures in Strangulation Revealed by Xeroradiography. Pollanen MS, Bulger B, Chiasson D . 1995;40(2): 303-305. On this basis, although the presence of the hyoid fracture in strangulation is determined by the rigidity of the bone, the specific location is determined by the shape of the greater cornu. These results indicate that fractures of the hyoid occur at vulnerable angles of curvature of the hyoid bone which, due to anatomic variation in hyoid shape, do not necessarily occur at specific segments of the hyoid bone.

This image shows the human hyoid bone, which helps to support the tongue and serves as an attachment point for several muscles that help to elevate the larynx during swallowing and speech.

The hyoid bone and cricoid cartilage are then brought together using three submucosal sutures of 0 prolene which are looped around the cricoid cartilage and the hyoid bone. The thyrohyoid membrane connects the superior border of the thyroid cartilage with the inferior margin of the greater cornu of the hyoid bone. http://www.utmb.edu/oto/Grand_Rounds_Earlier.dir/Conservative_Larynx_Surgery_1996.txt      Submandibular Region, Nasal & Oral Cavities - Dissector Answers midline raphe and body of the hyoid bone splits around intermediate tendon of digastric to insert on the body of the hyoid bone Note: W&B (277) points out that "the paralingual space...is continuous with the space of the submandibular triangle." Although the hyoglossus, a tongue muscle, is found in the submandibular triangle, it will be fully treated with the other tongue muscles in the fourth objective. http://anatomy.med.umich.edu/head/submand_ans.html      eMedicine - Conservation Laryngeal Surgery, Supracricoid Laryngectomy : Article by Stephen Y Lai, MD, PhD Hyoid: The hyoid bone is the most superior portion of the laryngeal skeleton and serves as the point of attachment for the strap muscles and suprahyoid musculature. The hyoid bone is rarely involved by laryngeal lesions and can be spared in resection of supraglottic carcinoma unless tumor is found at the level of the tongue or within the vallecula. The reconstruction for this more extensive technique is accomplished by suturing the cricoid to the hyoid, termed a cricohyoidopexy (CHP). http://www.emedicine.com/ent/topic570.htm      Hyoid bone - Wikipedia, the free encyclopedia The hyoid bone( Os Hyoideum ; "Lingual Bone") is a bone in the human neck, not articulated to any other bone; it is supported by the muscles of the neck and in turn supports the root of the tongue. The hyoid bone is shaped like a horseshoe, and is suspended from the tips of the styloid processes of the temporal bones by the stylohyoid ligaments. The hyoid is ossified from six centers: two for the body, and one for each cornu. http://www.wikipedia.org/wiki/Hyoid      c340chp3.txt 3.4.2.3 Mylohyoid: Trough shaped, forms muscle floor of mouth [3-39] - origin is mylohyoid line on inner surface of mandible - fibers course medially and downward to midline raphe (seam) - insertion is body of hyoid bone- action is elevates the hyoid bone. 102-110) Bone associated with the larynx 3.2.1 Hyoid bone.
