Answer:
C. parasympathetic
Step-by-step explanation:
The autonomic nervous system continuously sends impulses to the visceral organs, whose functional activity depends at every moment on the sympathetic and parasympathetic discharge rhythm.
The parasympathetic nervous system acts to restore the normal functioning of the body after it has experienced stress, nerves or adrenaline release. That is, heart rate, blood pressure and adrenaline levels return to normal. This system is also called the rest and digestion system.
In the parasympathetic autonomic nervous system, the fibers come from the midbrain, the bulb, and the sacral region of the spinal cord and form part of the cranial nerves III, VII, IX, and X, d of the pelvic nerve from the lower part of the medulla.
