Acetylcholine (ach) is released from motor neurons and enters the
a. sarcomere
b. transverse tubules
c. synaptic cleft
d. axon terminal

c. synaptic cleft

Explanation:

A neuromuscular junction is formed between a motor neuron and a muscle fiber called as sarcolemma. A signal is passed from motor neuron to muscle fiber which eventually leads to muscle contraction.

Motor neurons release the neurotransmitter Acetylcholine in synaptic cleft. Acetylcholine diffuses through it and ultimately binds to the  nicotinic acetylcholine receptors  on cell membrane of sarcolemma. Nicotinic acetylcholine receptors are ligand gated ion channels and get depolarized by binding to acetylcholine which results in muscle contraction.

it will take around no amount of ruffe to knock over this 110lbs man because he semms to be around 300lbs. lol

answer:

there is no cure for hiv, although antiretroviral treatment can control the virus, meaning that people with hiv can live long and healthy lives. most research is looking for a functional cure where hiv is reduced to undetectable and harmless levels in the body permanently, but some residual virus may remain. most commonly hiv-antivirals are taken also known as nucleoside/nucleotide reverse transcriptase inhibitors (nrti's).
