Detailed explanation-1: -You also have a nerve bundle at the base of your spinal cord called the cauda equina. The cauda equina comes from the Latin words for “horse’s tail, ” because early anatomists thought the nerve collection looked like a horse tail. The cauda equina includes nerves that provide sensation to your lower body.

Detailed explanation-2: -The cauda equina (from Latin tail of horse) is a bundle of spinal nerves and spinal nerve rootlets, consisting of the second through fifth lumbar nerve pairs, the first through fifth sacral nerve pairs, and the coccygeal nerve, all of which arise from the lumbar enlargement and the conus medullaris of the spinal cord.

Detailed explanation-3: -The spinal cord is a long bundle of nerves that runs down the length of the spinal column, and within that bundle, different nerves are grouped together.

Detailed explanation-4: -Spinal nerves are mixed nerves that interact directly with the spinal cord to modulate motor and sensory information from the body’s periphery. Each nerve forms from nerve fibers, known as fila radicularia, extending from the posterior (dorsal) and anterior (ventral) roots of the spinal cord.

Detailed explanation-5: -spinal cord, major nerve tract of vertebrates, extending from the base of the brain through the canal of the spinal column. It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain.
