The hyoid bone is the origin or insertion point for many muscles relating to deglutition, and it is possible that its position changes in cases of atypical deglutition (Bibby, 1984). 42-8). The tip of each horn is a slightly expanded tubercle that serves as the attachment for the lateral thyrohyoid ligament. Small islands of bone within this suture are called wormian bones. 65, Issue.
