Summary Introduction

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.

Expert Solution & Answer

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.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)
