What Is Cauda Equina Syndrome?
The spinal cord extends from the base of the brain to the area between the bottom of the first lumbar vertebra and the top of the second lumbar vertebra, and its main function is the transmission of nerve signals between the peripheral nervous system and the brain.
The spinal cord ends by diverging into individual nerves that travel out to the lower body and legs. Because of its appearance, this group of nerves is called the cauda equina – the Latin name for “horse’s tail.” Cauda equina syndrome is caused by significant narrowing of the spinal canal that compresses the nerve roots below the level of the spinal cord.
