What is the clear colorless fluid that protects and nourishes the brain and spinal cord called?

The correct terminology for the clear colorless fluid that protects and nourishes the brain and spinal cord is cerebrospinal fluid (CSF). The term “cerebral spinal” closely resembles this correct term, indicating that it pertains to both the brain (cerebral) and the spinal cord (spinal). The cerebrospinal fluid plays critical roles, such as cushioning the brain and spinal cord, providing mechanical protection, and circulating nutrients and waste products.

The other terms provided, while related to fluids in the neurological context, do not accurately represent the standardized term used in medical and scientific terminology. "Cerebral fluid" and "spinal fluid" are not specific enough and do not convey the dual function regarding both the brain and the spinal cord. "Neural fluid" is also not a recognized term in this context and does not reflect the specific nature and function of cerebrospinal fluid.
