Expert Solution
Step 1

An action potential is a characteristic pattern of quick rise and subsequent decline in voltage or membrane potential across a biological membrane. Neurons and muscle cells are two types of cells that communicate via action potentials. The stimuli initiate the abrupt change in voltage or action potential.
