Answer 2

Answer:

The pia mater is in direct contact with the brain in humans and the correct option is (d)

Explanation:

Our central nervous system consists of the brain and the spinal cord. The cranium (skull) encases the brain.

Inside the skull and vertebral column, three protective connective tissue coverings, the meninges, lie between the bony covering and the nervous tissue. The brain is covered by cranial meninges.

• The outermost is the dura mater which is composed of dense, irregular connective tissue.
• The arachnoid mater is the middle one.
• The innermost is the pia mater, a thin transparent connective tissue layer that adheres to the surface of the brain.
• Between the arachnoid mater and the pia mater is the subarachnoid space, which contains cerebrospinal fluid.

So, we can say that the pia mater is in direct contact with the brain in humans.

Hence the correct option is (d)
