SCALP stands for:
which layers can move in the scalp
first three layers
aponeurosis attaches to 2 muscles
occipital and frontalis
3 reasons why scalp wounds bleed so much
1. rich anastamoses between internal/external carotid
2. scalp wounds gap
3. fibrous septa restrict small artery constriction

Trigeminal V1 goes through which orifice?
superior orbital fissure
Trigeminal V2 goes through which skull hole?
Trigeminal V3 goes through which skull hole?
describe the facial nerve's path
off of external carotid, tortuous and gives off branches to nose and face
describe the superficial temporal artery
comes off of external carotid artery
name branches of internal carotid for the face
3 important branches of external carotid artery to head:
difference between facial vein vs. artery?
