Anathomy apendicular muscles | Nursing homework help
The biceps brachii muscle is located in the upper arm and is responsible for movement of the elbow joint. It consists of two heads, a long and short head, which connect to the scapula (shoulder blade) via tendons and attach to the radius bone in 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). Additionally, it plays a role in supination or turning your hand palm up, which involves rotating the radioulnar joint. This muscle also aids in stabilization during activities like carrying heavy objects or pushing against an object like when performing an overhead press motion.
