"Summary"
"The digastric muscle is composed of two bellies, anterior and posterior, connected by an intermediate round tendon that slides under a fibrous sheath attached to the greater horn of the hyoid bone. Both bellies are located superficially within the neck, deep to platysma, with the posterior belly passing deep to the sternocleidomastoid muscle at its insertion on the mastoid process."
