Explanation:
Detailed explanation-1: -The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale . Distal to this end of the spinal cord is a collection of nerve roots, which are horsetail-like in appearance and hence called the cauda equina (Latin for horse’s tail).
Detailed explanation-2: -The collection of nerves at the end of the spinal cord is known as the cauda equina, due to its resemblance to a horse’s tail. The spinal cord ends at the upper portion of the lumbar (lower back) spine.
Detailed explanation-3: -The spinal cord ends around L1, consequently, the caudal nerve roots below the first lumbar root, form the cauda equina.
