B. above, above
C. below, above
D. below, below

16. In the cervical vertebrae and the thoracic vertebrae, spinal nerves corresponding to the vertebrae emerge where, respectively (excluding T1)?
A. above, below
C. below, above

D. L1/L2

19. The cauda equina typically lies in the lumbar cistern below which vertebral level in an adult?
D. L1/L2

20. The spinal cord ends at L1/2 level, and the cauda
equina is the collection of nerve rootlets below it.

A. lateral horn
B. dorsal horn
C. ventral horn
D. medial horn

25. Where, in the spinal cord, are the motor neurons that innervate skeletal muscle?
A. lateral horn
C. ventral horn

C. dorsal, dorsal
D. dorsal, ventral

38. Deep back muscles are innervated by dorsal primary
rami, while ventral rami innervate limb muscles.
