Question

Which of the following most accurately describes how the sympathetic and parasympathetic nervous systems differ?

A. The sympathetic system is responsible for "rest and digest" functions, while the parasympathetic system is responsible for "fight or flight" responses.
B. The sympathetic system primarily uses acetylcholine as its neurotransmitter, while the parasympathetic system primarily uses norepinephrine.
C. The sympathetic system has short preganglionic fibers and long postganglionic fibers, while the parasympathetic system has long preganglionic fibers and short postganglionic fibers.
D. Both systems have identical functions and use the same neurotransmitters.

Answer 1

The sympathetic system is responsible for "fight or flight" responses, while the parasympathetic system is responsible for "rest and digest" functions.

Step-by-step explanation:

The sympathetic and parasympathetic nervous systems differ in several ways. The correct option that describes the difference accurately is:

A. The sympathetic system is responsible for "fight or flight" responses, while the parasympathetic system is responsible for "rest and digest" functions.

The sympathetic system prepares the body for emergency situations and increases heart rate, blood pressure, and glucose levels to provide energy. On the other hand, the parasympathetic system helps the body relax, slows heart rate, and stimulates digestion.
