Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Question

contraction occurs as the length of the muscle increases.
a. Concentric
O b. Eccentric
O c.
Static
O d. None of these
In regard to the force-length relationship, it is true that:
a.
The muscle length at which maximal active force occurs is called optimal length
b. Total force is equal to the sum of active and passive force
C.
All of these
d. Beyond resting length, passive force increases from short to long muscle lengths
