Which of the following are aspects of the structure of skeletal muscle? Select all that apply.       The muscle fibers are parallel to one another and have a striated appearance.   They have more mitochondria than other types of muscle cells.   Each fiber contains many units of contraction and protein filaments.   Cells are branched or unbranched with single nuclei.   It consists of cylindrical cells called muscle fibers that have multiple nuclei.

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.
