Chapter 7 External Cranium Flashcards
part of ethmoid that makes it a neurocranium bone
cribriform plate
bones of the neurocranium (6)
frontal, parietal, occipital, temporal, sphenoidal, ethmoidal
pterygoid muscles are for blank
chewing
these exit through holes in the foramen
cranial nerves
viscerocranium is the blank of the cranium
inside
paired bones of viscerocranium
maxillae, inferior nasal conchae, zygomatic, palatine, nasal, lacrimal
single viscerocranium bones
mandible, ethmoid, vomer
palatine bones are joined by a blank
suture
scalp cuts blank a lot because of blank which creates a large blank
bleed, muscles and aponeurosis separating, gape
five layers SCALP
skin, ct, aponeurosis, loose areolar tissue, pericranium
facial muscles are for blank
expression
innervation of facial muscles
facial nerve
facial nerve is cranial nerve blank
7
paralysis of entire half of face is from blank motor neuron
lower
example of lower motor neuron problem that paralyzes half the face
bells palsy
lower half of the face paralysis is from blank motor neuron lesion
upper
upper motor neuron is in the blank
cerebrum
example of upper motor neuron problem causing lower face paralysis
stroke
largest salivary gland and at TMJ
parotid
motor branches of cranial nerve seven
posterior auricular, temporal, zygomatic, buccal, marginal mandibular, cervical
there is no blank fascia on the face
deep
all facial muscles are in blank tissue
subcutaneous
cranial nerve ten
trigeminal nerve
three V branches of trigeminal nerve
V1 ophthalmic, V2 maxillary, V3 mandibular
