Muscles remain partially contracted even when not actively being used. The partial contraction gives the muscles some firmness known as muscle tone or tonus. How is muscle tone important to the body? maintains the muscles in a state of readiness aids in balance, posture, and joint stabilization generates action potentials within muscle fibers constant use of ATP releases heat that warms the body

Solution

ANS: B. Aids in balance, posture and joint stabilization.

Explanation:

The slight contraction of the muscles is called as muscle tone. It is controlled by cerebellum.

Muscle tone function:

1. Good muscle tone can improve coordination and helps in maintain of upright posture.

2. Muscle tone can produce body heat. The total body muscle tone can produces a significant amount of body heat.

NOTE: Option D is not fully correct answer, because……

     Reason 1: The primary function of muscle tone is maintaining body posture.

     Reason 2: The Body heat is generating from various tissues in body. Not only from muscle tone.
