Factors Affecting Excitability & Contractility | Muscles | Humans | Biology

The following factors affect excitability and contractility and therefore alter in various ways, the nature of the simple muscle curve: Factor # 1. Strength and Duration of Stimuli: For stimulation to occur, two factors are necessary—a minimum strength and an adequate duration of the stimulus. Chronaxie, which includes both these factors is the measure of excitability of a tissue. Factor [...]
