In a parasympathetic division motor pathway,which neurotransmitter is released at the effector?

C)Epinephrine
D)Dopamine
E)Serotonin

Question

Quizplus · Accepted Answer

In the parasympathetic division of the autonomic nervous system, the motor pathways release the neurotransmitter acetylcholine to its target effector organs, such as smooth muscle, cardiac muscle, or glands. This neurotransmitter binds to specific receptors on the effector cells and results in stimulation or inhibition of their activity, depending on the context. Therefore, option B is the correct answer. The other neurotransmitters listed, such as norepinephrine, epinephrine, dopamine, or serotonin, are typically involved in other divisions of the autonomic nervous system or in other parts of the nervous system, but not in parasympathetic motor pathways.
