Introduction:
Meninges is the protective layer that envelops the brain and spinal cord. It is a three-layered structure. The layers of meninges include an outer layer, a middle layer. Another innermost layer is also present. Subarachnoid space implies the area below the arachnoid region.
Answer to Problem 1DYKB
Correct answer:
The correct answer is option (b) Pia mater.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) Pia mater. Te deep or the inner layer of the meninges is the pia mater. The subarachnoid space lies between the arachnoid region and the pia mater.
Explanation for incorrect answer:
Option (a) Arachnoid mater. It is one of the three layers of the meninges. It is not the deepest or innermost layer and it lies above the subarachnoid space. Hence, this is an incorrect answer.
Option (c) Dura mater. It is the first and the outermost layer of the meninges. Hence, this is an incorrect answer.
Option (d) It is the region that lies below the dura mater. It is not the inner layer of the meninges. Hence, this is an incorrect answer.
