Origin

The digastric branch of nerve to mylohyoid muscle is the only branch of the nerve to the mylohyoid muscle. It originates on the superficial surface of the mylohyoid muscle.

Its motor fibers have cell bodies located in the motor nucleus of the trigeminal nerve.

Course

The digastric branch of the mylohyoid nerve runs from its origin on the superficial surface of the mylohyoid muscle medially to the anterior digastric muscle, which rests against the superficial surface of the mylohyoid muscle.

Branches

There are no named branches.

Supplied Structures

The digastric branch of the mylohyoid nerve is a motor nerve that transmits branchial motor efferent fibers to the anterior belly of the digastric muscle.

It is important to note that the posterior belly of the digastric muscle is not supplied by this nerve, but by a branch of the facial nerve.
