Question

When an action potential reaches the end of sending neuron’s axon, the signal turns from electrical to chemical, as the neurotransmitter is released. Drugs often affect these neurotransmitters. Drugs that enhance or mimic neurotransmitters are called agonists, whereas those that block neurotransmitters are called antagonists.

Investigate a specific neurotransmitter on the Internet. Discuss how your specific neurotransmitter is impacted by a drug (s) or substance (s) and possible influences on the person’s functioning?

*** Provide information from one or more scholarly sources with an in-text citation and match referencing to support your discussion. Wikipedia is not a scholarly source. Discussion without a source will receive zero (0) point.

Explanation / Answer

Acetylecholine(Ach.) is a small molecule neurotransmitter that is in one major respect like professor who is late for a lecture.

"Created By adding ain an acetyl group to choline molecule "

Acetylcholine is the neurotransmitter at neuromuscular junctions , at many of the synapses in the autonomic nervous system and at synapses in several parts of the cns.

Neurons that release acetylcholineqare said to be cholinergic

A drug that affects acetylcholine is nicotine. When ACh interacts with a nicotinic ACh receptor, it opens a Na+ channel and Na+ ions flow into the membrane. causing depolarization, resulting in an excitatory post-synaptic potential. Hence , ACh is excitatory on skeletal muscle; the electrical response is fast and short-lived. this is the reason you get a sense of euphoria after smoking for a couple of seconds
