1. FACE
Dr Rakesh Verma

2. 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

3. 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.

4. 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).

5. 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).
