Upper Limb Anatomy – FAQ
The upper limb consists of three main bones: the humerus, radius, and ulna. The humerus is the long bone in the upper arm, while the radius and ulna are the two bones in the forearm. Together, these bones provide structure and support for the arm’s movements.
The muscles of the upper limb are responsible for a wide range of movements, including flexion, extension, abduction, and rotation. Key muscle groups include the deltoids, biceps, triceps, and the muscles of the forearm. These muscles work together to allow for precise and powerful movements.
The shoulder joint, or glenohumeral joint, is a ball-and-socket joint that provides a high degree of mobility to the upper limb. It allows for a wide range of movements, including lifting, rotating, and swinging the arm. This joint’s flexibility is crucial for performing everyday tasks and complex motions.
Nerves play a crucial role in controlling the movements and sensations of the upper limb. The brachial plexus is a network of nerves that originates from the spinal cord and innervates the arm. These nerves transmit signals that control muscle contractions and provide sensory feedback from the skin and other tissues.
Common injuries to the upper limb include fractures, dislocations, and tendonitis. Treatment varies based on the injury’s severity and type but often includes rest, physical therapy, and, in some cases, surgery. Prompt medical evaluation and appropriate treatment are essential for effective recovery and preventing long-term complications
