The two bellies end in an intermediate tendon which perforates the Stylohyoideus muscle, and is held in connection with the side of the body and the greater cornu of the hyoid bone by a fibrous loop, which is sometimes lined by a mucous sheath.

The anterior body supplied by the trigeminal via the mylohyoid nerve. The anterior belly arises from a depression on the inner side of the lower border of the mandible, close to the symphysis, and passes downward and backward. The posterior belly is supplied by a branch of the facial nerve. The posterior belly, longer than the anterior, arises on the inferior surface of the skull, from the medial surface of the mastoid process of the temporal bone and a deep groove between the mastoid process and the styloid process called the digastric groove. The two bellies of the digastric muscle have different embryological origins, and are supplied by different cranial nerves. The Digastricus (Digastric muscle) consists of two fleshy bellies united by an intermediate rounded tendon. It belongs to the suprahyoid muscles group.Ī broad aponeurotic layer is given off from the tendon of the Digastricus on either side, to be attached to the body and greater cornu of the hyoid bone this is termed the suprahyoid aponeurosis. It lies below the body of the mandible, and extends, in a curved form, from the mastoid process to the symphysis menti. The digastric muscle (named digastric as it has two bellies) is a small muscle located under the jaw. List of terms related to Digastric muscleĮditor-In-Chief: C.
