GENERAL HISTOLOGY

Detailed explanation-1: -In adults, the cord terminates at the level of L1-L2. Thus the cord spans within 20 bony vertebrae. In a child, it terminates at the upper border of L3. Each of these segments innervates a dermatome.

Detailed explanation-2: -In human, the spinal cord ends at L2 vertebral level. The tip of the spinal cord is called the conus. Below the conus, there is a spray of spinal roots that is frequently called the cauda equina or horse’s tail. Injuries to T12 and L1 vertebra damage the lumbar cord.

Detailed explanation-3: -The vertebral canal is composed of the vertebral foramen located in the cervical, thoracic, and lumbar vertebrae. The vertebral or spinal cord typically ends at the level of the L2 vertebra, where the spinal cord gives off multiple branching spinal nerves and nerve rootlets known as the cauda equina.

Detailed explanation-4: -L2, L3 and L4 spinal nerves provide sensation to the front part of your thigh and inner side of your lower leg. These nerves also control hip and knee muscle movements.

Detailed explanation-5: -The spinal cord terminates in the lumbar spine. The exact point of termination varies among individuals; most commonly, it terminates at the level of the L1 or L2 vertebrae.
