The sympathetic and parasympathetic nervous systems are divisions of which system?

The correct answer is The autonomic nervous system (ANS).

Explanation:

The autonomic nervous system (ANS) controls the internal region of the human body. This type of nervous system takes information to the central nervous system which controls the internal parts like the gut, the heart by releasing noradrenaline and adrenalin from the adrenal gland and other.

The ANS has 2 divisions which are the parasympathetic division and the sympathetic division -

The sympathetic division can be defined as stress neurons or fight or flight neurons because it makes the body ready to prevent it from the impact of the injury.

The parasympathetic division function to recover and replace the activities of living. It has an antagonist effect in comparison to what sympathetic division does.

Thus, The correct answer is The autonomic nervous system (ANS).
