ANATOMY

Detailed explanation-1: -Digastric is a small paired muscle located in the anterior compartment of the neck. It belongs to a group of muscles called the suprahyoid muscles. Besides the digastric, this group also contains the mylohyoid, geniohyoid and stylohyoid muscles.

Detailed explanation-2: -The anterior belly is attached to the digastric fossa on the base of the mandible close to the midline and runs toward the hyoid bone. The posterior belly is attached to the notch of the mastoid process of the temporal bone and also runs toward the hyoid bone [10].

Detailed explanation-3: -It is a flat and triangular muscle that originates from the mandible near the molars hence the prefix “mylo” (Greek for molars) and inserts on the hyoid bone. The mylohyoid mainly functions to elevate the hyoid bone, elevate the oral cavity, and depress the mandible.

Detailed explanation-4: -The digastric muscle (also digastricus) has two bellies, namely the anterior and posterior belly. It is a small, important muscle in the neck.

Detailed explanation-5: -The posterior belly is supplied by the digastric branch of facial nerve. The digastric muscle stretches between the mastoid process of the cranium to the mandible at the chin, and part-way between, it becomes a tendon which passes through a tendinous pulley attached to the hyoid bone.
