1. Subdural space

2. White matter

3. Dorsal root

4. Ventral root

5. Vertebral body

6. Epidural space

7. Gray matter

(1). Subdural space: It is a potential area between the spinal dura mater and the arachnoid mater. It doesn’t contain any bridging veins. That’s why hemorrhage in this area occurs very rarely.

(2). White matter: It consists of most of the glial cells and myelinated axons. It is white because of myelin (fatty substances) that surrounds the nerve fibers. It is located in the outer region of spinal cord surrounding the gray matter.

(3). Dorsal root: It emerges directly from spinal cord and expands to the dorsal root ganglion. It contains sensory fibers and carries the sensory information, forming afferent sensory root of a spinal nerve.

(4). Ventral root: It contains outgoing efferent motor fibers that carry the information destined to the control motor or to the glandular function. It joins with the dorsal root on the outside of the vertebral column to form a spinal nerve.

(5). Vertebral body: It is the main part of the vertebra and bears about the 80% of the load while standing. It provides an attachment to the discs in between the vertebrae.

(6). Epidural space: It is the area between the vertebral wall and the dura mater. It contains fat and blood vessels. The epidural space is found just outside the dural sac that surrounds the nerve roots and it is filled with the cerebrospinal fluid.

(7). Gray matter: It consists of neuronal cell bodies, glial cells, neuropil, capillaries, and synapses. It is found deep inside the core of spinal cord.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
