Describe each muscle needed to contract for specific movement and each muscles action during that action. Each muscle firing is it's own step. Something simple like kicking a ball is one action with multiple muscles firing it that action. You need at least 5 muscles involved in your action Example: Description: Picking up a glass of water. Muscles: Biceps, brachialis. Step 1: The brachialis has an origin at the humerus and inserts at the ulna. Contracting is a flexion action. Example: The [Muscle] has an origin at the [Bone] and inserts at the [Bone]. Contracting is a [Action] action

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.
