from the side of the body and from the whole length of the greater cornu of the hyoid bone.

The fibers arising from the body of the hyoid bone overlap those from the greater cornu.

Note, posteriorly, the lingual nerve is superior to the submandibular duct and a portion of the submandibular salivary gland protrudes into the space between the hyoglossus and mylohyoid muscles.

The hyoglossus depresses and retracts the tongue and makes the dorsum more convex.
