mus·cle tone(mŭs'ĕl tōn)
1. The internal state of muscle-fiber tension within individual muscles and muscle groups.
Also termed tonus; the normal state of balanced tension in the tissues of the body, especially the muscles.
Mentioned in: Contractures
muscle tonesyn 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.
muscle tonebackground tension within resting muscle tissue (due to random activation of small numbers of muscle motor units)
A state of partial contraction present in a muscle in its passive state as, for example, when the eye is in the physiological position of rest. Syn. muscle tone. See resting state of accommodation; physiological position of rest; tonic vergence.
Patient discussion about muscle tone
Q. what sort of diet should I take to tone up my muscle and to lose fat in my body? Is steroid a good idea?
A. as williams41 say- it's a BAD idea... steroids wil damage your body immune system and can get you more prone to bacterial/virus/fungal attacks. it also have unhealthy side effects that one of them is distribution of fat in the face area that can be unpleasant. so consider your steps...More discussions about muscle tone
