Question

Imagine you are studying a neuron from the autonomic nervous system. It does not innervate the adrenal medulla. The neuron is very long. When you perform an immunohistochemistry experiment you find that it is positive for the enzymes that synthesize norepinephrine, and negative for the enzymes that synthesize acetylcholine. This neuron is a_________

Answer 1

The question is incomplete as it does not have the options which are:

a. motor neuron.

b. preganglionic sympathetic neuron

c. preganglionic parasympathetic neuron.

d. a postganglionic parasympathetic neuron

e. a postganglionic sympathetic neuron.

Answer:

E) a postganglionic sympathetic neuron.

Step-by-step explanation:

The autonomic nervous system controls the autonomic responses in the body and is divided into the sympathetic and parasympathetic system.

In the given question, the characteristic of a neuron has been described that it is a long neuron which can synthesize the norepinephrine but not the acetylcholine.

From the provided options, the neurons which are long are the neurons of the preganglionic parasympathetic neuron and postganglionic sympathetic neuron. But out of these two, the acetylcholine neurotransmitter is used by the postganglionic sympathetic neurons.

Therefore, Option-E is the correct answer.
