Flashcards in Face Scalp Parotid Deck (38)
scalp extends down to where?
includes forehead and supreorbital margins
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
once any laceration breaches loose CT what happens?

in the face layers, instead of aponeurosis there is?
muscles arise from? insert?
arise from bone of fascia
insert into skin of face
facial muscles arise from what?
2nd pharangeal arch
Anterior skin to front of ears innervated by?
trigeminal (CN V)
3 divisions of trigeminal:
posterior skin until behind ears innervated by?
dorsal rami of cervial nerves
C1 does which sensory innervation nerves?
what is trigeminal neuralgia?
intense period of facial pain
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?
vein is straighter, less tortuous
risk of what with popping a pimple in the nose/upper lips areas?
thrombophlebitis of facial vein
there is a ring of lymph nodes at base of skull: 6 regions are:
Location of parotid gland:
below zygomatic arch
ant. to mastoid process/ear
above angle of mandible
posterior to masseter
superficial to styloid process
parotid gland wrapped in? affected in which condition?
affected in Mumps
trace the parotid gland salivary pathway to the mouth
emerges anterior border
turns medially, pierces buccinator
enters near second upper molar
