1. =Panniculus carnosus.=—The facial panniculus (M. cutaneus faciei)
consists of a thin and usually incomplete muscular stratum, which covers
the submaxillary space and the masseter muscle. A branch from it passes
forward to the angle of the mouth and blends with the orbicularis oris;
this part (M. cutaneus labiorum) retracts the angle of the mouth. (A
number of the superficial muscles of the face may be considered modified
parts of the panniculus, _e. g._, the corrugator supercilii, malaris,
zygomaticus, etc.)
