Detailed explanation-1: -The lowermost tapering extremity of the spinal cord is called the conus medullaris, which is around the first or second lumbar vertebra and can sometimes be lower.
Detailed explanation-2: -Anatomy Explorer At its inferior end, the spinal cord tapers to a point known as the conus medullaris and gives rise to many large nerve fibers known as the cauda equina. The cauda equina descends through the vertebral canal from the conus medullaris to the coccyx.
Detailed explanation-3: -The cauda equina (CE) is a bundle of intradural nerve roots at the end of the spinal cord, in the subarachnoid space distal to the conus medullaris. Cauda is Latin for tail, and equina is Latin for horse (ie, the “horse’s tail").
Detailed explanation-4: -The conus medullaris is the terminal end of the spinal cord, which typically occurs at the L1 vertebral level in the average adult. [1] Conus medullaris syndrome (CMS) results when there is compressive damage to the spinal cord from T12-L2.
Detailed explanation-5: -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).
