Definitions:

Treppe

A phenomenon observed in cardiac muscle, where successive stimuli result in increasingly stronger contractions, described as the "staircase effect."

Wave Summation

A phenomenon in muscle physiology where repeated stimulation of a muscle fiber leads to an increase in the strength of muscle contraction.

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.
