The sympathetic nervous system differs from the parasympathetic nervous system in that . a. the sympathetic nervous system has no first-stage neurons. b. no second-stage neurons. c. first-stage neurons that synapse at a substantial distance from the target organ. d. first-stage neurons that synapse close to the target organ. e. both B and C

One of the functional differences between the sympathetic and parasympathetic nervous system is that in the sympathetic nervous system first stage neurons have synapses a considerable distance from the target organ (Option C).

Explanation:

Sympathetic nervous system is part of the autonomic nervous system, and is responsible for producing the body's activating response, such as increased heart rate, pupil dilation, and increased muscle strength and endurance. The main neurotransmitters of this system are epinephrine (adrenaline) and norepinephrine.

One of the fundamental characteristics of the sympathetic nervous system is its ability to release neurotransmitters even when they are far from the receptors, while the nerve ganglia of the parasympathetic nervous system must be close to the target organs.
