Question

multiple choice 2 points
under normal circumstances, both divisions of the autonomic nervous system are active simultaneously.
false
true

Explanation:

Define autonomic nervous system divisions

Using the Autonomic Nervous System knowledge point
The autonomic nervous system (ANS) consists of two primary divisions: the sympathetic nervous system and the parasympathetic nervous system.

Analyze simultaneous activity and autonomic tone

The sympathetic and parasympathetic divisions are not "all-or-nothing" systems. Under normal circumstances, both divisions are active simultaneously to maintain homeostasis. This continuous, background level of activity from both divisions is known as autonomic tone. Rather than turning completely off, one division increases its activity while the other decreases it depending on the body's immediate physiological needs. Therefore, the statement is true.

Answer:

• false
• true (Correct answer)
