THE HYOID BONE Flashcards
the hyoid bone
is a u-shaped bone found on the anterior of the neck below the mandible(C6)
it acts as a site of attachment for anterior neck muscles
structure
- body is the central part of the bone, it convex anteriorly and concave posteriorly.
- greater wings- projects from each end of the body in a posterior, superior, and lateral direction. It acts as a site of attachment for numerous neck muscles.
- Lesser horn – arises from the superior aspect of the hyoid bone, near the origin of the greater horn. It projects superoposteriorly (toward the styloid process of the temporal bone). The stylohyoid ligament attaches to the apex of the lesser horn.
it does not articulate with any other bones and is suspended in place by the muscles and ligaments that attach to it.
true
which muscle does not attach to the hyoid bone
The sternothyroid arises from the manubrium of the sternum and attaches to the thyroid cartilage.
ligament attachments
Stylohyoid ligament – extends from the styloid process of the temporal bone to the lesser horn of the hyoid bone.
Thyrohyoid membrane – originates from the superior border of the thyroid cartilage and attaches to the posterior surface of the hyoid bone and the greater horns.
Hyoepiglottic ligament – connects the hyoid bone to the anterior aspect of the epiglottis.
