The platysma is a pharyngeal arch 2 muscle and a superficial facial muscle that participates in oral/pharyngeal behaviors and is innervated by the cervical branch of the facial nerve. It attaches to the mandible and it attaches to the skin of the head, neck, and thoracic region where it is found superficial to the clavicle. Burrows et al. (2011) argue that in hylobatids (and, presumably, other primates) the platysma in the region of the modiolus represents both the cervicale and myoides muscles. [ MFMO:0000059 ]

comment

Human variation notes: Variations occur in the extension over the face and over the clavicle and shoulder; it may be absent or interdigitate with the muscle of the opposite side in front of the neck; attachment to clavicle, mastoid process or occipital bone occurs. A more or less independent fasciculus, the occipitalis minor, may extend from the fascia over the trapezius to fascia over the insertion of the sternocleidomastoideus.
