Summary Introduction

Introduction:

Arachnoid mater is present external to the pia mater. It is composed of a network of collagen and elastic fibers. Cerebrospinal fluid is present in this space. The network of fibers is called as arachnoid trabecula.

Expert Solution & Answer

Answer to Problem 1DYKB

Correct answer:

Arachnoid mater is present deep inside the subdural space. The space present inside the meninges is called as subdural space. Therefore, option a. is correct.

Explanation of Solution

Reasons for the correct statement:

Option a. is given as “arachnoid mater”. Arachnoid mater is present on the inner side of meninges into subdural space. Hence, arachnoid mater is present inside the subdural space.

Hence, option a. is correct.

Reasons for incorrect statements:

Option b. is given as “pia mater”. It is the innermost layer of the spinal cord and is composed of a network of collagen and elastic protein fibers. Hence, option b. is incorrect.

Option c. is given as “dura mater”. It is composed of connective tissue network with an outer layer of the periosteal layer and inner meningeal layer. Hence, option c. is incorrect.

Option d. is given as “epidural space”. It is present between the dura mater and inner region walls of the vertebra. Hence, option d. is incorrect.

Hence, options b., c., and d. are incorrect.

Conclusion

Arachnoid mater is present deep inside the meninges layer and contains cerebrospinal fluid which maintains the internal environment of the spinal cord for conduction of the signal impulses in the neuronal cells.
