The main function of the cerebrospinal fluid is

A) to provide saltatory transmission.
B) to provide nutrients for the neurons.
C) defense of the nervous system against pathogens.
D) to produce gray matter.
E) to cushion and protect the central nervous system.

Cerebrospinal Fluid

A clear, colorless body fluid found in the brain and spinal cord, acting as a cushion for the brain's cortex, providing basic mechanical and immunological protection to the brain inside the skull.

Saltatory Transmission

The rapid propagation of nerve impulses along myelinated axons from one Node of Ranvier to the next, increasing the speed of electrical signal transmission.

Central Nervous System

The part of the nervous system comprising the brain and spinal cord, responsible for processing and sending out information to the rest of the body.
