What are the 5 motor branches of the facial nerve from top to bottom?
Temporal Zygomatic Buccal Marginal mandibular Cervical
TZ BMC
What does the facial nerve (VII) supply?
Frontalis
Occipitalis
Orbicularis oculi - forcefully closing eyelids
Orbicularis oris - closing the mouth

Platysma - a superficial muscle found in the neck
What does the facial nerve leave the skull through?
The Stylomastoid foramen
What does the parotid duct penetrate?
The buccinator
What is the masseter supplied by?
The mandibular V3 division of the trigeminal nerve
What are the branches of the trigeminal nerve named after?
Supraorbital foramen/nerve from the ophthalmic V1
Infraorbital foramen/nerve from the maxillary V2
Mental foramen/nerve from the mandibular V3
Where does the auriculartemporal nerve come from?
A branch of V3 (maxillary)
Purely sensory
What is unique about the facial arteries and veins?
They are valveless
Where is the facial artery and vein from?
The external carotid
And the internal jugular
Where does the parotid gland open up?
Near the 2nd upper molar
What is the sensory nerve in the area of the facial nerve?
The auriculartemporal nerve
What can happen to wind instrument players in the parotid gland?
Pneumoparotid
When air is forced in the parotid duct
Where does the lateral pterygoid muscle take origin and insert?
Inferior surface of the greater wing of the sphenoid
Inserts into the TMJ
What does the inferior alveolar nerve (a branch of V3)pass through?
The mandibular foramen
What branches off the inferior alveolar nerve before it enters the mandibular foramen?
