b. lumbar enlargement.
c. cauda equina.
d. conus medullaris.
10 which of the following spaces around the spinal cord is filled with adipose tissue?
a. epidural space.
b. subdural space.
c. subarachnoid space.
d. all of the above.

Explanation:

• Question 9: The conus medullaris is the tapered, lower end of the spinal cord. The filum terminale is a fibrous extension from the conus medullaris. The lumbar enlargement is an area of the spinal cord with a larger diameter (due to more neurons for the lower limbs). The cauda equina is a collection of spinal nerves below the conus medullaris.
• Question 10: The epidural space is the space between the dura mater and the vertebral wall and is filled with adipose tissue. The subdural space is a potential space (not normally present, but can fill with fluid in injury). The subarachnoid space is filled with cerebro - spinal fluid.

Answer:

• 9. d. conus medullaris
• 10. a. Epidural space
