Face Flashcards
Sensory nerve for face and the motor innervation for muscles of mastication
Trigeminal nerve
Cnv3 has some motor fibers
Orbicularis oculi 3 parts
Palpebral- gently closes eyelids
Lacrimal - aids in drainage of tears
Orbital part- tightly closes the eyelids
Motor nerve of the face
Facial nerve
Mandibular ( cnv3)
6 branches of facial nerve

Ends in the scalp by dividing into frontal and parietal branches
What provides the primary superficial venous drainage of face? And where does this vein begin?
Facial vein and begins at the medial angle of the eye as the angular vein.
The facial vein drains directly into the…
Internal jugular vein
The great auricular nerve provides sensory innervation to…
