Explain or draw the structure of a neuromuscular junction, complete with all is anatomical promoting the propagation of action potentials down the length of a muscle. That is, how do action potentials propagate along a muscle fiber You are a prominent genetic engineer in the early 1900s and are decades ahead of your time (and everyone else!). You have characterized the types of vesicles that CNS ncurons use to package their neurotransmitters. In doing so, you have cloned and then expressed the genes for neurotransmitter uptake proteins, ATP-dependent H" channels, and of course, vesicles. Knowing that the vast majority of small-molecule neurotransmiters are cations at plysiological pll, diagram how neurons would package its neurotransmitters into vesicles 4.Explanation / Answer
