Question

7 cerebrospinal fluid is produced by the
a. dural sinuses.
b. choroid plexuses.
c. ventricles.
d. meninges.

Explanation:

Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spinal cord. The choroid plexuses, which are tufts of capillaries and ependymal cells, are responsible for producing CSF. Dural sinuses are involved in venous drainage. Ventricles are cavities that contain CSF but do not produce it. The meninges are protective membranes around the brain and spinal cord and do not produce CSF.

Answer:

B. choroid plexuses.
