The platysma is a superficial fascial muscle in the upper chest, neck, and lower face.

The Platysma is primarily located in the neck, but is a muscle of facial expression of the lower face and mouth. The muscles of facial expression of the mouth are:



  • Fascia of the upper chest and neck to the mandible and fascia of the lower face.



  • Creates wrinkles in the neck.
  • Depresses and draws laterally the lower lip.
  • Depresses the mandible at the temporomandibular joints (TMJs)



  1. The platysma is considered to be the remnant of a muscle in quadrupeds called the panniculus carnosus. This muscle enables four-legged animals to shake off flies and other insects.
  2. Contraction of the platysma creates the characteristic expression of the monster from the film The Creature from the Black Lagoon.
