Overview
Muscle electrophysiology is the study of the electrical activity of muscle tissue and how that activity governs muscle function. Skeletal, cardiac, and smooth muscle cells generate and respond to electrical signals: changes in the voltage across the cell membrane, driven by the movement of ions such as sodium, potassium, and calcium through specialized channels, produce action potentials that trigger contraction. The field examines how nerve impulses are transmitted at the neuromuscular junction, how excitation is coupled to the mechanical shortening of muscle fibres, and how the electrical properties of muscle change with exercise, disease, or injury. Techniques such as electromyography record this activity and are used both in research and in the clinical diagnosis of neuromuscular and cardiac disorders. As a journal focused on physiology, this page situates muscle electrophysiology within the broader study of how the body's tissues and systems function. Related peer-reviewed work indexed here includes a study addressing cardiac physiology and the maintenance of cardiac hemodynamics and electrophysiology across reproductive stages, which touches on the electrical behaviour of heart muscle. The page assembles encyclopedic reference information on muscle electrophysiology, including membrane excitability and excitation-contraction coupling, consistent with the journal's physiological scope.
