Question 8

body of vertebrae

Answer 8

protect spinal cord anteriorly

Question 9

vertebral arch

Answer 9

protects spinal cord posteriorly

Question 10

Answer 11

muscle and ligament attachment point (posterior)

Question 12

yellow ligament

Answer 12

preserve upright posture

Question 13

posterior longitudinal ligament

Answer 13

prevent trunk hyperflexion

Question 14

vertebral artery

Answer 14

provide blood supply to upper spinal cord, brainstem, and parts of the brain

Question 15

gray matter

Answer 15

contains cell bodies, dendrites, and axon terminals

Question 16

white matter

Answer 16

contains axons that connect gray matter

sympathetic trunk

Answer 19

allow nerve fibers to travel to spinal nerves

Question 20

cerebellum

Answer 20

motor skills such as balance, coordination, and posture
