Question

multiple choice question
which statement accurately describes the cauda equina?

a thin cord of connective tissue runs from the conus medullaris to the coccyx
a bundle of spinal nerves extending inferiorly from the conus medullaris
an enlarged area of the spinal cord thickened due to a large number of spinal nerves associated with it

Explanation:

• The first option describes the filum terminale (connective tissue cord), not cauda equina.
• The cauda equina is a bundle of spinal nerves (lumbar, sacral, coccygeal) that extend inferiorly from the conus medullaris (end of the spinal cord).
• The third option describes the cervical or lumbosacral enlargements of the spinal cord, not cauda equina.

Answer:

B. A bundle of spinal nerves extending inferiorly from the conus medullaris
