Study Notes
Facial Muscles and Nerve Supply
- The main nerve supply for the motor function of the facial muscles is the facial nerve (cranial nerve VII).
Sensation of the Face
- The trigeminal nerve (cranial nerve V) is responsible for supplying sensation to the skin of the face.
Muscles of Facial Expression
- The muscles of facial expression are located in the subcutaneous tissue of the face.
Blood Supply to the Face
- The facial artery is the main source of blood supply to the face.
- The facial artery follows a curved course, arising from the external carotid artery, and then ascending deep to the submandibular gland and platysma muscle, before turning upwards and outwards to supply the face.
Septal Branch of the Nasal Septum
- The superior labial artery gives a septal branch to the nasal septum.
Facial Artery Pulsation
- The pulsation of the Facial Artery can be felt at the anterior border of the masseter muscle.
Facial Vein and Tributaries
- The tributaries of the Facial Vein correspond to the branches of the Facial Artery.
Superficial Temporal Vein
- The Superficial Temporal Vein drains into the maxillary vein.
Formation of the Common Facial Vein
- The Facial Vein joins the anterior branch of the Retromandibular Vein to form the Common Facial Vein.
