Alex recently quit smoking. now he has trouble paying attention at work and forgets simple things. which neurotransmitter is most likely causing alex's symptoms?
acetylcholine ( t/f)

True

Explanation:

Tobacco is consumed during smoking which contains an addictive substance called Nicotine. Nicotine exerts its effect on the body by stimulating the acetylcholine receptors in the neurons. The stimulation of these receptors stimulates another neurotransmitter like glutamate, dopamine and GABA which produce addictive effects in humans.

Since the acetylcholine is involved in stimulating the other neurotransmitters therefore true is the correct answer.

Thus, true is the correct answer.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
