Nursing homework assistance| Nursing homework help

The upper arm’s biceps Brachii muscle controls movement at the elbow joint. The biceps brachii muscle consists of two heads: a short and long head. They connect via tendons to the shoulder blade and the radius bone at the forearm. The primary function of this muscle group is forearm flexion – meaning it helps bring your forearm towards your shoulder – as well as assisting with shoulder abduction (lifting your arm away from your body). Supination is when your hand turns up by turning the radioulnar joint. It also helps stabilize activities such as lifting heavy objects and pushing against them like performing overhead presses.
