The end of the spinal cord where nerves descend
A
coccygeal
B
cauda equina
C
lumbrosacral
D
femoral
Explanation: 

Detailed explanation-1: -The cauda equina is a group of nerves and nerve roots stemming from the distal end of the spinal cord, typically levels L1-L5 and contains axons of nerves that give both motor and sensory innervation to the legs, bladder, anus, and perineum.

Detailed explanation-2: -A group of nerve roots that travel down from the spinal cord and the conus medullaris is called the cauda equina. The cauda equina contains nerve roots from L2 in the lumbar spine to Co1 in the coccygeal (tail bone end) spine.

Detailed explanation-3: -Anatomy. The spinal cord ends around L1, consequently, the caudal nerve roots below the first lumbar root, form the cauda equina.

Detailed explanation-4: -At the bottom of the spinal cord (conus medullaris) is the cauda equina, a collection of nerves that derives its name from the Latin translation of “horse’s tail” (early anatomists thought the collection of nerves resembled a horse’s tail).
