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.

Detailed explanation-2: -Anatomically, the spinal cord runs from the top of the highest neck bone (the C1 vertebra) to approximately the level of the L1 vertebra, which is the highest bone of the lower back and is found just below the rib cage.

Detailed explanation-3: -L2 spinal nerves affect sensation in the front portion of the upper thighs. The muscles involved in bending the hips (hip flexors) and bringing the legs together (hip adductors) are also connected to the spinal cord at this level.

Detailed explanation-4: -The spinal cord ends at the intervertebral disc between the first and second lumbar vertebrae as a tapered structure called the conus medullaris, consisting of sacral spinal cord segments. The upper border of the conus medullaris is often not well defined.
