Question

1. what triggers motor responses within the autonomic nervous system?

fear
illness
exercise
depression

Explanation:

The autonomic nervous system regulates involuntary motor responses. Fear activates the sympathetic branch of this system, triggering fight-or-flight motor responses (e.g., increased heart rate, pupil dilation). Illness, exercise, and depression may impact autonomic function but are not direct triggers of its core motor response pathways in the same immediate, innate way fear is.

Answer:

fear
