Tonus is the continous baseline muscle tone in the body.
The state of activity or tension of a muscle beyond that related to its physical properties, that is, its active resistance to stretch. In skeletal muscle, tonus is dependent upon efferent innervation. A constant state of slight tension that serves to maintain the muscle in a state of readiness is known as tonus.
Tonus is muscular or body tone. Tonus is defined as the continuous contraction of a muscle in the skeleton system which aids in the return of blood to the heart.

Tonus
Toni- is the medical terminology combining form meaning tonus. The stimulation of individual muscle fibers maintains a state of muscle contration. This is important in maintaining the movement of blood and lymph through out the body

Muscle tone is the name for muscle's state of perpetual partial tension. It helps maintain posture, balance, and readiness for movement.
The state of partial skeletal muscle contraction is known as tonus. Muscles of the body do not have a real state of total relaxation.
1. Even when a muscle appears to be at rest, a certain amount of sustained contraction is occurring in its fibers. This is called muscle tone. (Muscle tone is a response to nerve impulses that originate repeatedly from the spinal cord and stimulate a few muscle fibers.) A tetanic contraction is when a forceful sustained contraction lacks even partial relaxation.

The psychological condition characterized by extreme tonus is called catatonia. Catatonia is a state of psychomotor disturbance that can include immobility, excessive movement, or other abnormal behaviors related to muscle tone.
