What is the upper limb?

The upper limb refers to the entire arm of the human body, including the shoulder, upper arm, forearm, wrist, and hand. It is responsible for carrying out various functions such as lifting, grasping, and manipulating objects. The upper limb is essential for performing daily activities and tasks that require dexterity and strength.

What are the bones that make up the upper limb?

The upper limb consists of the following bones: clavicle, scapula, humerus, radius, ulna, carpals (wrist bones), metacarpals (palm bones), and phalanges (finger bones).

What is the largest bone in the upper limb?

The largest bone in the upper limb is the humerus, which is located in the arm and extends from the shoulder to the elbow.

What are the two bones that make up the forearm?

The two bones that make up the forearm are the ulna and the radius. The ulna is located on the inner side of the arm, while the radius is located on the outer side. These bones work together to provide support, stability, and movement to the forearm and hand.

What is the joint that connects the upper limb to the axial skeleton?

The joint that connects the upper limb to the axial skeleton is the sternoclavicular joint. This joint is formed by the articulation between the clavicle and the sternum, specifically at the manubrium of the sternum. It is the only bony connection between the upper limb and the trunk, providing stability and allowing a wide range of motion for activities involving the shoulder and arm.

What are the three major joints of the upper limb?

The three major joints of the upper limb are the shoulder joint (glenohumeral joint), elbow joint, and wrist joint. These joints are crucial for the mobility and functioning of the arm, allowing for a wide range of movements and dexterity in daily activities.

What are the muscles that move the upper limb?

The muscles that move the upper limb include the deltoid, pectoralis major, latissimus dorsi, biceps brachii, triceps brachii, brachioradialis, flexor carpi ulnaris, extensor carpi radialis longus, and muscles of the rotator cuff (supraspinatus, infraspinatus, teres minor, and subscapularis).

What is the main nerve that supplies the upper limb?

The main nerve that supplies the upper limb is the brachial plexus, a network of nerves that originate from the spinal nerves in the neck and travel down into the shoulder, arm, and hand.

What are the major blood vessels that supply the upper limb?

The major blood vessels that supply the upper limb include the subclavian artery, which branches into the axillary artery, leading to the brachial artery that further divides into the radial and ulnar arteries. These vessels provide oxygenated blood to the entire upper limb, including the shoulder, arm, forearm, and hand.

What are the main functions of the upper limb?

The main functions of the upper limb include providing mobility and dexterity, allowing us to perform activities such as reaching, grasping, lifting, pushing, and pulling. It also plays a crucial role in communication through gestures, balance and stabilization of the body, and overall support in daily tasks. Additionally, the upper limb aids in sensing the environment through touch, temperature, and pressure receptors, contributing to our perception and interaction with the world around us.
