Platysma: The platysma is one of the paired muscles of the neck. The platysma originates on the clavicle and fascia that covers the superior part of the pectoralis major and deltoid muscles and inserts on the skin of the lower face and mandible. The platysma lowers the lower lip and mandible, or jaw bone, and tightens the fascia of the neck. It is innervated by the cervical branch of the facial nerve.
Conditions that can afflict the platysma include overuse injuries, tears, strains, myopathy, atrophy, infectious myositis, neuromuscular diseases, lacerations and contusions.
