A

first three layers

3
Q

aponeurosis attaches to 2 muscles

A

occipital and frontalis

4
Q

3 reasons why scalp wounds bleed so much

A
  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?

A

profuse bleeding

arise from bone of fascia

insert into skin of face

Q

posterior skin until behind ears innervated by?

A

dorsal rami of cervial nerves

14

Foramen Ovale

19
Q

describe the facial nerve’s path

A

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

20

A

superifical temporal
posterior auricular
occipital

23
Q

difference between facial vein vs. artery?

A

vein is straighter, less tortuous

24
Q

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

A

thrombophlebitis of facial vein
