Musculoskeletal Physiologic Processes

Medical Definition:	Biological actions and events that support the functions of the MUSCULOSKELETAL SYSTEM.
Guide Notes:	not used for indexing or cataloging

Musculoskeletal Physiologic Processes Categories.

	Exertion - Expenditure of energy by skeletal muscles. Intensity of exertion may be measured by rate of oxygen consumption, heat produced, or heart rate. Perceived exertion, a psychological measure of exertion, is included.
	Movement - The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.
	Muscle Contraction - A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.
