- The wrist is a complex joint that bridges the hand to the forearm. It is actually a collection of multiple bones and joints. The bones comprising the wrist include the distal ends of the radius and ulna, 8 carpal bones, and the proximal portions of the 5 metacarpal bones (see the images below).Bones of the wrist, palmar view.

- Wrist Flexors and Extensors. The wrist flexors mainly consist of 1) flexor carpi radialis and 2) flexor carpi ulnaris. These muscles are located in the anterior forearm region on both sides of the body.

Hand â Bones, Ligaments, Muscles & Conditions Intrinsic muscles only act on the fingers. The extrinsic muscles are the long flexors and extensors, which run from the forearm into the hand, providing strength to the hand and wrist. The flexors enable the fingers to bend while the extensor muscles are used to straighten the fingers.

The Wrist Joint The wrist joint (also known as the radiocarpal joint) is a synovial joint in the upper limb, marking the area of transition between the forearm and the hand.In this article, we shall look at the structures of the wrist joint, the movements of the joint, and the relevant clinical syndromes.he wrist joint receives blood from branches of the dorsal and palmar carpal arches, which are derived from the ulnar and radial arteries (for more information, see Blood Supply to the Upper Limb). Innervation to the wrist is delivered by branches of three nerves: 1  Median nerve – Anterior interosseous branch.

The Wrist Joint Movements of the Wrist Joint. The wrist is an ellipsoid type synovial joint, allowing for movement along two axes. This means that flexion, extension, adduction and abduction can all occur at the wrist joint. All the movements of the wrist are performed by the muscles of the forearm. Flexion – Produced mainly by the flexor carpi ulnaris, flexor carpi radialis, with assistance from the flexor digitorum superficialis.

Muscles in the Posterior Compartment of the Forearm The general function of these muscles is to produce extension at the wrist and fingers. They are all innervated by the radial nerve. Anatomically, the muscles in this compartment can be divided into two layers; deep and superficial. These two layers are separated by a layer of fascia.

Wrist Movements The wrist is capable of three sets of distinct movements. 1  Flexion and extension. 2  Supination and pronation. 3  Ulnar deviation (ulnar flexion) and radial deviation (radial flexion).lnar deviation, otherwise known as ulnar flexion, is the movement of bending the wrist to the little finger, or ulnar bone, side. With the right hand this is the movement you use when hitting the Enter key.

Wrist Movements The neutral position of the wrist is that position where the wrist is in straight alignment with the forearm: no flexion, extension, radial or ulnar deviation.The wrist is at the mid-point between supination and pronation.This is commonly called the handshake position.ith the right hand this is the movement you use when hitting the Enter key. Radial deviation, otherwise known as radial flexion, is the movement of bending the wrist to the thumb, or radial bone, side.

- Extensor tendons are located on the back of the hand and fingers and allow you to straighten your fingers, wrist and thumb (See Figure 1).These tendons are attached to muscles in the forearm. As the tendons continue into the fingers, they become flat and thin. In the fingers, these tendons are joined by smaller tendons from the muscles in the hand.

Anatomy The extensor carpi radialis brevis (ECRB) muscle helps stabilize the wrist when the elbow is straight. This occurs during a tennis groundstroke, for example. When the ECRB is weakened from overuse, microscopic tears form in the tendon where it attaches to the lateral epicondyle.

What are Phalanges? The function of the hand phalanges is to provide dexterity to the hand; foot phalanges help provide stability to the foot and disperse weight. The fingers and toes, or digits, have a network of muscles which insert along the bones and attach to various portions of the hand or wrist, depending on its function or primary purpose.

Wrist Anatomy The anatomy of the wrist joint is extremely complex, probably the most complex of all the joints in the body. The wrist is actually a collection of many bones and joints. These bones and joints let us use our hands in lots of different ways. The wrist must be extremely mobile to give our hands a full range of motion. At the same time, the wrist must provide the strength for heavy gripping.
