opthamalmic division of trigemnal.
What part of skin does facial nerve innervate?
None, it does muscles motor to muscles of facial expression!
superifical laryngeal nerve runs with what and innervates what?
splits into internal and exernal parts.

external does cricothyroid and inferior pharyngeal constrictor muscles.

superior, middle and (maybe inferior?) constrictors are innervated by vagus through pharyngeal plexus
crocildile tears results from?

epidural
subdural hemorgaing is from? subpial?
subdural from bridging cerebral veins

subpail from vessels of pia

subarachnoid from cerebral arteries and veins

oblique arytenoid and aryepiglottic muscles
only muscle of the larynx not innervated by recurrent laryngeal?
cricoithyroid.
Only muscle that opens (abducting) the space between the vocal cords to allow for sound production.
posterior cricothyroid. via recurrent laryngeal from vagus
sphincter and close the larynx as we swallow or cough?
aryepiglottic muscle together with the transverse arytenoid and the thyroarytenoid
