Question

What is muscle tonus?explain it in detail please.

Answer 1

the steady reflex contraction that resides in the muscles concerned in maintaining erect posture. Tonus has its basis in the positional interactions of the muscle and its accompanying nerve structure; e.g., a muscle holds the body (mandible) in a given position, and the awareness of this position is constantly being relayed by the sensory approaches to the cortex. A change in position or contractility of the muscle that affects its tonus is immediately relayed by the sensory apparatus for readjustment. Also called tone.
