Chapter 28, Problem 1PL
The ____________ is the most superficial membrane o(the meninges.
a. subarachnoid space
b. piamater
c. arachnoid mater
d. duramater
Expert Solution & Answer
Summary Introduction
Introduction:
Meninges covers and protects the brain and spinal cord. It is made of three layers in mammals which are dura mater, arachnoid mater and pia mater. Cerebrospinal fluid is present between arachnoid mater and pia mater.
Answer to Problem 1PL
Correct answer:
The correct answer is option (d) dura mater.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) dura mater. Dura mater is the outermost superficial layer of meninges. It lies just next to the skull and vertebrae. It is loosely arranged with many extracellular spaces. It is a sac-like structure and envelops arachnoid mater. So, the correct answer is option (d).
Explanation for incorrect answer:
Option (a) subarachnoid space. It is the space between arachnoid mater and pia mater. It contains cerebrospinal fluid. This fluid cushions the brain and spinal cord. So, this is an incorrect option.
Option (b) pia mater. It is the third and innermost layer of meninges. It is a thin membrane that attaches to the brain and spinal cord. So, this is an incorrect answer.
Option (c) arachnoid mater. It is the second and middle layer of meninges. It is a thin membrane and the cells are tightly packed so that there is no leakage of fluid. So, this is an incorrect answer.
