Definitions:

Latent Period

The time interval between the application of a stimulus and the response, common in muscle physiology and reaction time studies.

Excitation-Coupling

The process linking muscle fiber excitation to contractions via the transduction of electrical signals to mechanical actions.

Refractory

Resistant to treatment or control, often used to describe a period of unresponsiveness or insensitivity to stimuli.

Power Stroke

The phase in muscle contraction where the myosin head pivots, pulling the actin filament towards the center of the sarcomere, shortening the muscle.
