Musculoskeletal and Neural Physiological Phenomena

A Medical Subject Headings category covering physiological processes and functions of the musculoskeletal and nervous systems.

Neurophysiology: The study of how the nervous system functions, including neural signaling and sensory processing. It covers the nervous-system processes grouped within this category.
Action Potential: A rapid, transient change in a cell's membrane voltage that propagates along excitable cells. Neurons use action potentials to carry signals toward muscles and other targets.
Gait: A person's pattern of walking, including the timing and coordination of limb movements. Walking exposes the coordinated neural and musculoskeletal functions in this category.
Cardiovascular Physiological Phenomena: Physiological processes and functions of the heart and blood vessels. It covers circulation rather than neural signaling or musculoskeletal function.
Muscle Contraction: The process by which muscle fibers generate tension, often producing movement. It is a central physiological function of the musculoskeletal system.
Neuromuscular Junction: The synapse where a motor neuron communicates with a skeletal muscle fiber. It converts neural output into the signal that initiates muscle contraction.
Postural Control: The regulation of body position and balance through sensory input and coordinated muscle activity. It combines neural feedback with sustained musculoskeletal action.
Respiratory Physiological Phenomena: Physiological processes and functions involved in breathing and gas exchange. It focuses on ventilation and gas exchange, not movement or neural control.
Synaptic Transmission: The transfer of signals between neurons or from neurons to other cells at synapses. It explains how neural activity is passed between cells.
Excitation–Contraction Coupling: The processes linking electrical excitation of a muscle fiber to its contraction. It connects nerve-triggered electrical activity to muscular force.
