Important ligaments

Question 1

alar ligaments check what

Answer 1

(check or dentate ligaments)

checks rotation and lateral bending

upper alar check contralateral bending

lower alar check ipsilateral rotation

Question 2

apical ligament is locate where

Answer 2

(suspensory ligament)

top of dens

Question 3

transverse ligaments check what

where is it located

Answer 3

(portion of cruciate ligament)

checks flexion and extension

located in groove posterior to dens with synovium on either side

Question 4

flava ligament checks what

Answer 4

(yellow ligament - made of elastin)

FLEXION - main ligament that checks flexion of the spine

Question 5

ALL

Question 6

Answer 6

PLL

Question 7

PLL is thinnest at

Answer 7

L5

Question 8

which ligament is damaged in hyper flexion

Answer 8

interspinous and nuchal ligament

Question 9

Rectus capitis posterior major attaches to what

Rectus capitis posterior minor attaches to what

Answer 9

major - attaches to meninges between C1-2

minor - attaches to meninges between C0-1

Question 10

what are the 3 things cause immobility

Answer 10

dehydration - decrease water in proteoglycans - connective tissue contracts - decrease extensibility

altered motion - shorten hyperactive muscles - inflammation - ossification

posture/gravity - venous plexus dependent on gravity - immobility increases toxins which accelerate DJD
