Question

Cerebrospinal fluid is manufactured in the:

a) Subarachnoid space.
b) Anterior pituitary gland.
c) Ventricles of the brain.
d) Posterior pituitary gland.

Answer 1

Cerebrospinal fluid is manufactured in the ventricles of the brain by the choroid plexus and ependymal cells. It circulates through the ventricular system and enters the subarachnoid space.

Step-by-step explanation:

Cerebrospinal fluid is manufactured in the ventricles of the brain. The choroid plexus, which is a specialized membrane, produces CSF within the ventricles. Ependymal cells filter the blood to create CSF, which is a clear solution containing water, small molecules, electrolytes, and dissolved oxygen and carbon dioxide. The CSF then circulates through the ventricular system and enters the subarachnoid space through apertures.
