Answer 7

masetter, temporalis

Question 8

which muscle does lateral exursion & protrusion?

Answer 8

lateral pteryogoid
medial pterygoig

Question 9

True Torticollis presents as?

Answer 9

ipsilateral side bend with contralateral rotation
(tight SCM); more common in infants

Question 10

discogenic/facet/acute/wry neck torticollis presents as

Answer 10

lateral bend and rotation away from involved side with slight flexion;
doing all these motion to involved side will cause pain cause compression on facet or disc.

extension most limited

Question 11

nucleus pulposa properties

Answer 11

~80% water and rest type II collagen

Question 12

the outer layer of annulus fibrosis is type ___ collagen while the inside layer is type __ collagen

Answer 12

I; II (more flexible)

Question 13

Canadian C spin rules are highly sensitive; screen if need for radiograph, if negative can rule it out.

Question 14

function of tectoral membrane

Answer 14

prevents excessive flexion from occiput to C2 and turns into posterior lig.

Question 15

anterior longitudinal lig function

Answer 15

limites extension

Question 16

posterior longi. lig function

Answer 16

limits flexion & reinforces back of annulus

Question 17

alar ligs

Answer 17

limit head rotation & side bend on contralateral side
attach to the dens bilaterally and insert on the base of the skull.

Question 18

lig flavum

Answer 18

connects laminae
assists spine to return to neutral from flexion and relaxes during extensions

Question 19

lig nuchae

Answer 19

attachment site for trap & spleniu capitis
from occiput to C7
prevents excessive flexion

Question 20

transverse lig

Answer 20

anchors dens in place and provides stability

Question 21

side bend to L side at OA joint (C0-C1)

Answer 21

ipsilateral side: MIA
medial, inferior, anterior

contralateral side LPS
lateral, posterior, superior

Question 22

C1 & C2 vertebra (convex on convex)
rotating to the R

Answer 22

MOST ROTATION
rotating to the R
the R inferior facet of C1 moves posterior on C2
The L inferior facet of C1 moves anterior on C2

Question 23

rotation at C2-C7

Answer 23

rotating to the R:
inferior facet on the L has to glide sup and anterior
inferior facet on R has to glide post and inf.

Question 24

C1 and C2 will rotate in oppsoite direction during side bending to keep ur head looking straight while and lower cervical spine, those vertebra rotate slightly to to same direction of bend
