What is the name of the inferior tip of the spinal cord?

Cauda equina and filum terminale seen from behind. The dura mater has been opened and spread out, and the arachnoid mater has been removed. The conus medullaris (Latin for “medullary cone”) or conus terminalis is the tapered, lower end of the spinal cord.

The conus medullaris marks the official “end” of the spinal cord proper (usually at the level of the first lumbar ver- tebra). Inferior to this point, groups of axons collectively called the cauda equina (kaw ́dăē-kwı̄ ́nă) project inferiorly from the spinal cord.

How far inferior does the spinal cord extend?

The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) long in adult men and around 43 cm (17 in) long in adult women.
