8/6 Questions Exam 1

Question 1

What is the relationship between scoliosis and tethered cord syndrome?

Answer 1

it is suggested that the column will change normal curvatures to mitigate damage to the spinal cord

Question 2

What is the relationship between spinal nerve number, rib number, and vertebral number in a thoracic intervertebral foramen?

Answer 2

the spinal nerve number relates to the upper segment number in the vertebral couple the rib number relates to the lower segment number in the vertebral couple
Ex. T3 nerve exits the intervertebral foramen formed by T3/T4 and rib 4 joints with this vertebral couple

Question 9

What would be the direction of the cervical curve based on osseous features?

Answer 9

posterior or kyphotic

Question 10

What accounts for the direction of the typical cervical curve?

Answer 10

the intervertebral disc height

Question 11

What is the direction of the typical cervical curve?

Answer 12

C5/C6

Question 13

What is the effect of aging on the cervical vertebral body?

Answer 13

Question 14

What are the modifications of the superior epiphyseal rim of a typical cervical?

Answer 14

anterior groove, posterior groove, right and left uncinate processes

Answer 17

anterior lip, posterior lip, right and left lateral grooves

Question 18

What is the joint classification for the anterior lip-anterior groove articulation?

Answer 18

fibrous (amphiarthrosis) syndesmosis

Question 19

What is the joint classification for the uncinate process-lateral groove articulation?

Answer 19

modified synovial saddle (diarthrosis sellar)

Question 20

What is the joint classification for the spongy bone-intervertebral disc articulation?

Answer 20

cartilaginous (amphiarthrosis) symphysis

Question 21

How many joint surfaces are present on the upper surfaces of a typical cervical vertebral body?

Answer 21

five

Question 22

How many joint surfaces are present on the vertebral body of a typical cervical?

Answer 22

ten

Question 23

What is the name given to the uncinate process-lateral groove articulation?

Answer 23

joint of Luschka or uncovertebral joint

Question 24

What is the functional significance of the joint of Luschka?

Answer 24

it appears to stabilize the intervertebral disc while accommodating flexion - extension and requiring coupled motion (axial rotation with lateral bending) in the cervical spine
