Head & Neck Flashcards
describe extent of scalp
describe layers of the scalp
explain diploe
3 components on a skull bone
compact bone
periosteum
spongy bone (diploe)
list the cutaneous nerves of the scalp
INNERVATION of scalp anterior to auricles is by branches of all 3 divisions of trigeminal
Posterior to auricles is by spinal cutaneous nerves (C2 and C3)
describe the distribution of dermatomes of the scalp
Trigeminal nerve = CNV1 , CNV2, CNV3
Spinal nerves = anterior (C2/3) and posterior rami (C2/3)

3 layers of the eyeball
fibrous coat
vascular coat
sensory coat
contents of fibrous coat
sclera - posterior 5/6
cornea - anterior 1/6
sclera
gives attachment to muscles moving eyeball to
cornea function
transparent
window to allow light rays to enter the eyeball
ciliary body
