Answer to Question 1

A
Explanation: The dura mater is the tough and fibrous outer sac of the meninges. The pia mater is the innermost membrane layer that is applied directly to the brain and spinal cord. The subdural space is the actual space between the dura mater and arachnoid layers. The arachnoid layer is a thin, delicate layer attached to the pia mater by web-like filaments.

Answer to Question 2

B
Explanation: Agranulocytes do not have granules in their cytoplasm, granulocytes do. The other statements are true.
