Descripción

Origin: Tubercle of mandible

Insertion: Modiolus of mouth

Artery: Facial artery

Nerve: Mandibular branch of facial nerve

Action: Depresses angle of mouth

Description:
Depressor anguli oris arises from the oblique line of the mandible, whence its fibers converge, to be inserted, by a narrow fasciculus, into the angle of the mouth. At its origin it is continuous with the Platysma, and at its insertion with the Orbicularis oris and Risorius; some of its fibers are directly continuous with those of the Caninus, and others are occasionally found crossing from the muscle of one side to that of the other; these latter fibers constitute the Transversus menti.
