Facial skeleton and Face
Objectives
By the end of this lab students are expected to be able to
1. Discuss the major regions and features of human face
2. Identify major bones of facial skeleton and their prominent features
3. Locate major muscles of facial expressions
4. Recognize the five terminal branches of facial nerve
5. Correlate between facial nerve anatomy and its palsy
6. Discuss the pattern of sensory innervation of the face
7. Locate main sensory nerves of the face
8. Describe course and deep communications of facial vein.

Note: Place the palm of your hand over the auricle and spread your five digits on the face. The
five digits now represent the course of the five terminal branches of facial nerve.
Note: Facial nerve is the most frequently paralyzed of all the peripheral nerves of the body.
 Sensory supply:
 Trigeminal nerve
1. Ophthalmic nerve (branches in the face?)
2. Maxillary nerve (branches in the face?)
3. Mandibular nerve (branches in the face?)
 Great auricular nerve
 Blood supply
 Facial artery
 Transverse facial artery
 Venous drainage:
 Facial vein
Deep communications (with cavernous sinus)
1- Superior ophthalmic vein
2- Deep facial vein
 Retromandibular vein
Home work:
1- Where does the dangerous area of the face lie?
Deep communications of facial vein
