Action Potentials in the Heart Spread from Cell to Cell

Question

Action potentials in the heart spread from cell to cell through
A)desmosomes.
B)gap junctions.
C)interneurons.
D)valves.
E)coronary vessels.

Accepted Answer

Action potentials in the heart spread from cell to cell through gap junctions, which allow for a rapid transmission of electrical signals between adjacent cells. Desmosomes, interneurons, valves, and coronary vessels do not play a role in the propagation of action potentials in the heart.
