scalp extends down to where?

includes forehead and supreorbital margins

1

SCALP stands for:

Skin
Connective Tissue
Aponeurosis
Loose CT
Periosteum

2

which layers can move in the scalp

first three layers

3

aponeurosis attaches to 2 muscles

occipital and frontalis

4

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

5

once any laceration breaches loose CT what happens?

profuse bleeding

6

in the face, what layer do you not have compared to scalp?

loose CT

7

in the face layers, instead of aponeurosis there is?

facial muscles

8

muscles arise from? insert?

arise from bone of fascia
insert into skin of face

9

Face
spincters:
dilators:

orbicularis
depressor/levator

10

facial muscles arise from what?

2nd pharangeal arch

11

Anterior skin to front of ears innervated by?

trigeminal (CN V)

12

3 divisions of trigeminal:

opthalmic (V1)
maxillary (v2)
mandibular (V3)

13

posterior skin until behind ears innervated by?

dorsal rami of cervial nerves

14

C1 does which sensory innervation nerves?

None

15

what is trigeminal neuralgia?

intense period of facial pain

16

Trigeminal V1 goes through which orifice?

opthalmic
superior orbital fissure

17

Trigeminal V2 goes through which skull hole?

Maxillary
Foramen Rotundum

18

Trigeminal V3 goes through which skull hole?

Mandibular
Foramen Ovale

19

describe the facial nerve's path

off of external carotid, tortuous and gives off branches to nose and face

20

describe the superficial temporal artery

comes off of external carotid artery

21

name branches of internal carotid for the face

supraorbital:
supratrochlear:

22

3 important branches of external carotid artery to head:

superifical temporal
posterior auricular
occipital

23

difference between facial vein vs. artery?

vein is straighter, less tortuous

24

risk of what with popping a pimple in the nose/upper lips areas?

thrombophlebitis of facial vein

25

there is a ring of lymph nodes at base of skull: 6 regions are:

submental
submandibular
preauricular
parotid
mastoid
occipital

26

Location of parotid gland:

below zygomatic arch
ant. to mastoid process/ear
above angle of mandible
posterior to masseter
superficial to styloid process

27

parotid gland wrapped in? affected in which condition?

parotid fascia
affected in Mumps

28

trace the parotid gland salivary pathway to the mouth

emerges anterior border
onto masseter
turns medially, pierces buccinator
enters near second upper molar

29

name parotid gland layer superficial to deep

1. cranial nerve VII:facial
2. retromandibular vein
3. external carotid artery
4. scattered parotid lymph nodes

30

facial nerve exits skull where?

styloid mastoid foramen

31

what happens after facial nerve exits skull?

give off:
posterior auricular
occipitalis supply
posterior belly digastric
stylohyoid

32

after facial nerve enters parotid, what happens?

branches into a plexus called pes anserinus

33

name the 5 branches of facial nerve from top superior to inferior

Temporal
Zygomatic
Buccal
Mandibular
Cervical

34

retromandibular vein formed by things?

temporal and maxillary

35

external carotid artery divides into 2 big things

maxillary
superficial temporal

36

injury to facial nerve causes?

facial droop

37

most common cause of facial nerve dysfunction?

Bell's Palsy, unknown etiology, treat with steroids early
