The cauda equina is part of which system?

• A. Nervous
• B. Endocrine
• C. Digestive
• D. Immune

Answer: (A)

The cauda equina is part of the nervous system because it is a bundle of nerve roots that extend from the end of the spinal cord to the lower body, carrying motor and sensory signals to and from the legs and pelvic region. It isn’t a gland or hormone system (endocrine), nor is it involved in digestion or immune responses (digestive or immune systems). Knowing that it’s made of nerves helps you see why injuries here affect sensation and movement in the legs and can impact bladder or bowel control.
