FACE Dr Rakesh Verma

Objectives Explain the muscle of muscles of facial expressions with their nerve supply and discuss their actions. Discuss facial nerve palsy. Blood supply & lymphatic drainage of face

FACE The facial muscles or muscles of facial expression are subcutaneous. Most muscles attach to the bone or fascia and produce their effect by pulling the Skin.

FACE They move the skin and change facial expressions to convey mood. The basic shape of the face is determined by the underlying bones. All muscles of the facial expression are supplied by the VII cranial nerve (Facial nerve).

Muscles of facial expression Present in the superficial fascia of the face. Inserted into the skin of the face. Related to the three main orifices of the face (either sphincters or dilator).
