Explanation:
Glial cells are the cells present in both the type of nervous system in which they neither conduct electrical impulse nor generate them but they perform some other functions like support.
Astrocytes are one of the type of glial cells which are present in the central system of neurons that is in the spinal cord and the brain.
These astrocytes perform various other functions like
1. Form the blood-brain barrier as they enclose the blood capillaries in the brain preventing leakage.
2. They regulate ionic concentration around the neurons.
3. They can store and produce glucose from the non-carbohydrate source.
4. They control the flow of the blood in the brain
5. They can also play a role in the formation of synapses in the neurons.
The answer would be D, abdominopelvic. You can think of it as the region underneath the diaphragm and above the pelvic bone, which includes all of the organs you just listed.
Answer:
