d. parasympathetic and spinal systems.

Answer 1

The autonomic nervous system contains two branches: sympathetic and parasympathetic. The sympathetic system is activated in stress and the parasympathetic system is active during rest.

Step-by-step explanation:

The autonomic nervous system contains two branches called the sympathetic and parasympathetic systems. The sympathetic nervous system is activated in stressful situations to prepare the body for a "fight-or-flight" response, while the parasympathetic nervous system is active during restful periods. Together, these two systems regulate the unconscious control over visceral functions in the body.
