14. Which cranial nerve has the most parasympathetic neurons?

15. Is there a parasympathetic innervation to the adrenal gland?

Answer 1

The below are answers of first five questions,as the rest of the question numbrs are repetitive.

5. The cranial nerves III, VII, IX, X  contain parasympathetic neurons.

6.No cranial nerve have sympathetic fibers.

2.Chromaffin cells, they are modified neurons . The adrenal medulla is a mass of cells that make up the center of the adrenal gland beneath the outer adrenal cortex. These irregular-shaped cells are bunched together with blood vessels. Cells of the medulla are called chromaffin cells since they stain a brownish color in reaction to chromic salts.

3.The primary function of the sympathetic system is to stimulate your fight-or-flight response which is a physiological reaction that happens in response to a perceived harmful event, attack or threat to survival.

4.parasymathetic division of the ANS raises blood sugar and oxygen.
