A disease deactivates the acetylcholine receptors at myoneural junctions. Would this prevent muscle contraction or muscle relaxa
tion, and why? Relaxation, by preventing synaptic vesicles from releasing their contents
Contraction, by preventing synaptic vesicles from releasing their contents
Relaxation, by preventing an action potential from traveling across the sarcolemma
Contraction, by preventing an action potential from traveling across the sarcolemma
I think the correct answer is D. contraction, by preventing an action potential from traveling across the sarcolemma. Acetycholine lreceptors are found on the surface of muscle cells, concentrated in the synapse between nerve cells and muscle cells. When the nerve impulses reaches the axon terminals, a chemical called the neurotransmitter is released, in this case the acetylcholine that stimulates skeletal muscle cell. Therefore a disease that inactivates the acetylcholine will prevent the activation of the muscle.
This is straight forward.If there are 60 minutes in one hour, then to convert minutes to hours as requested, simply divide the number of minutes given by 60.Thus if you divided the 59 by 60 it gives you what?round the answer to whole number.
