Upper Extremity Anatomy – FAQ
The upper extremity, also known as the upper limb, consists of the shoulder, arm, forearm, wrist, and hand. It includes the bones, muscles, blood vessels, and nerves that facilitate movement and function. The upper extremity is essential for various complex tasks, from lifting to fine motor skills.
The key bones in the upper extremity are the humerus, radius, ulna, carpals, metacarpals, and phalanges. The humerus is the long bone in the upper arm, while the radius and ulna make up the forearm. The carpals form the wrist, metacarpals are in the hand, and phalanges are the finger bones.
Muscles in the upper extremity facilitate movement by contracting and relaxing to move bones at the joints. Major muscle groups include the deltoids, biceps, triceps, and forearm muscles. These muscles work together to enable a wide range of motions, such as lifting, pushing, pulling, and precise hand movements.
Nerves in the upper extremity transmit signals between the brain and muscles, allowing for sensation and movement. The brachial plexus is a network of nerves that originates from the spinal cord and extends into the arm, forearm, and hand. This nerve network is crucial for controlling muscle actions and sensing stimuli.
Injuries to the upper extremity often result from trauma, overuse, or repetitive strain. Common injuries include fractures, dislocations, tendonitis, and nerve compressions such as carpal tunnel syndrome. Prevention includes proper ergonomics, strength training, and avoiding repetitive stress. Treatment can range from rest and physical therapy to surgical intervention.
