The Cerebral Spinal Fluid

Question

The cerebral spinal fluid
A) is produced by the corpus callosum.
B) cushions the brain, delivers nutrients to the brain, and removes wastes.
C) circulates between the cranium and the brain.
D) is secreted by the astrocytes.

Accepted Answer

The cerebral spinal fluid (CSF) cushions the brain, delivers nutrients to the brain, and removes wastes. It is a clear, colorless liquid that circulates through the brain and spinal cord, protecting the delicate nervous tissue. The corpus callosum is a structure in the brain that connects the two hemispheres and does not produce CSF. Astrocytes are a type of glial cell in the brain that provide support and insulation, but they do not secrete CSF. CSF circulates within the ventricular system of the brain, not between the cranium and the brain.
