An arrow points to a specific muscle on the anterior (front) side of the arm.**Muscle Indicated:** Coracobrachialis**Action of the Coracobrachialis:**- **Primary Actions:** - Flexion of the shoulder joint - Adduction of the arm (bringing the arm towards the body)This muscle originates from the coracoid process of the scapula and inserts onto the medial humerus. It assists in stabilizing the shoulder joint during movement.

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.

Please order the steps of voluntary movement. 1) Primary motor cortex sends information to alpha motor neurons 2) The prefrontal and parietal cortices decide to initiate movement. 3) Alpha motor neurons initiate muscle contractions. 4) The supplementary motor area (SMA) uses input from the thalamus and basal ganglia to plan a movement.
