Question

CSF is secreted by ______.

विकल्प

• choroid plexus only.

• Pia mater and choroid plexus only.

• Pia mater, choroid plexus and ependymal cells lining the ventricles.

• White matter, Pia mater and grey matter.

Answer 1

CSF is secreted by pia mater, choroid plexus and ependymal cells lining the ventricles.

Explanation:

Cerebrospinal fluid is mainly produced by the Choroid plexus, but it is also contributed to by the Ependymal cells lining the brain ventricles and, to a lesser extent, by the Pia mater.

So, CSF is not secreted by a single structure alone, but by all three together.
