Refer to the figure showing muscle cells.
In the living tissue, if an action potential stimulates contraction of cell 1, will cell 2 also contract?
A) Yes, because an action potential in cell 1 will spread to cell 2 through gap junctions in structure A.
B) Yes, because the motor neuron A that innervates cell 1 also innervates cell 2.
C) No, because the action potential will be stopped by structure A, which separates cell 1 and cell 2.
D) Yes, because the smooth muscle cell labeled 1 will spread the action potential to cell 2 through the neuromuscular junction at A.
E) No, because the skeletal muscle cell labeled 1 is not physically connected to cell 2 through gap junctions.
