Unraveling Muscle Contraction

True or false: The action potential during muscle contraction is divided into four stages: resting membrane potential, depolarization, repolarization, and propagation?

True or false: There are four types of changes that occur during muscle contraction?

True or false: Electrical changes during muscle contraction are rapid changes in the membrane potential by which nerve signals are transmitted?

True or false: The origin of resting membrane potential during muscle contraction is mainly due to the diffusion of potassium ions from inside the cell to outside?

True or false: The diffusion of sodium ions from outside the cell to inside contributes to the resting membrane potential during muscle contraction?
