During tonic activity at rest, which of the following is true? A) Only somatic nervous system is active B) Parasympathetic nervous system is inactive C) Both branches of the autonomic nervous system are active D) Sympathetic nervous system completely dominates
Understand the Problem
The question is asking about the physiological state of the autonomic nervous system during tonic activity at rest and which statement correctly describes this state.
Answer
Both branches of the autonomic nervous system are active.
During tonic activity at rest, both branches of the autonomic nervous system are active.
Answer for screen readers
During tonic activity at rest, both branches of the autonomic nervous system are active.
More Information
Tonic activity means there is a constant, baseline level of activity in both the sympathetic and parasympathetic branches. They simultaneously monitor and regulate various involuntary bodily functions.
Tips
A common mistake is assuming that one branch is inactive or completely dominates during rest, while in fact, both autonomic branches contribute to maintaining homeostasis.
