tone

The degree of tension maintained in a muscle when not actively contracting. In health, this is slight. Tone is abolished in certain forms of paralysis and greatly increased in others.

muscle tone

syn tonus (1) in skeletal muscle, a state of tension that is maintained continuously - minimally even when relaxed - and which increases in resistance to passive stretch. Pathologically, loss of tone (flaccidity) can be caused, e.g. by peripheral nerve damage, and exaggerated tone (spasticity) by overstimulation, e.g. when the activity of the relevant lower motor neurons is released from higher CNS control in spinal injury. The term is sometimes also used, incorrectly, to indicate general muscle strength. (2) In smooth muscle, steady tension maintained in the walls of hollow vessels; regulated mainly by autonomic innervation but influenced, e.g. in the walls of arterioles, by local variables: temperature, chemical factors or intravascular pressure, contributing to autoregulation of appropriate blood flow. See also stretch reflex.
