The tendons that attach the forearm flexor muscles to the finger and hand bones on the palm side of the hand and wrist and serve to curl the fingers and thumb and bend the wrist.

The wrist tendons are. The flexor tendons and the extensor tendons. The carpal extensor retinaculum divides the dorsal extensor tendons into six separate synovial compartments which are demarcated by the points of its attachment to the radius and ulna.

Tendons and muscles supporting wrist joint movements are as follows- Abduction Radial Deviation of Wrist Joint- Abduction is movement of the hand around wrist joint towards thumb while palm is facing to ceiling. Wrist Tendons Flexor carpi radialis FCR tendon. The wrist tendons slide through smooth sheaths as they pass by the wrist joint.

The carpal bones are small. Tendons involved in wrist flexion or the action of bending the wrist forwardinward. Tendons of the wrist have two subgroups.

Flexor tendons and extensor tendons 20. Both tendons and ligaments are dense regular connective tissue because of its two properties. Each tunnel is lined internally by a synovial sheath and separated from one another by a fibrous septa.

When muscles contract they pull on the tendons to move the bones. Tenosynovitis may also result from an inflammatory process or infection. It is often the source of a common repetitive strain injury called carpal tunnel syndrome CTS.

The anatomy of the wrist and hand is best described by considering the extensor and flexor surfaces separately. Each compartment has its own separate tenosynovial sheath. Extensor carpi radialis longus extensor carpi radialis brevis III.

Muscles of the wrist and forearm. Nine major extensor tendons are located at the dorsal aspect of the wrist. The LCL passes from the end of the radius across the joint to the scaphoid.

These tendons are responsible for bending the wrist forward and backward flexion and extension. Tendons are white flexible rope-like cords at the ends of muscles that attach muscles to bone. Wrist tendons include the.

The tendons of the wrist are divided into two main groups. It articulates with the palmar surface of the triquetrum. The wrist also contains several soft tissues such as ligaments tendons nerves and blood vessels.

Injury to these tendons is often the result of repetitive trauma and overuse and most commonly presents as tendinosis and tenosynovitis. The tendons that run down our fingers are held in place by a series of ligaments called pulleys that form stable arches over tendons forming a tunnel-like sheath. Tendons are fibrous bands that connect muscle to bone.

It attaches to the base of the second and third hand bones. Extensor Tendons The tendons that attach the forearm extensor muscles to the finger and hand bones on the backside of the hand and wrist and serve to straighten the fingers thumb and wrist. Anatomy of the Wrist Tendons Tendons are structures that connect a muscle to bone and the wrist tendons connect the forearm muscles to the bones of the hand and fingers.

There are 6 tendons that help move your wrist. ECU - extensor carpi ulnaris EDM - extensor digiti minimi ED - extensor digitorum communis EPL - extensor pollicis longus ECRB - extensor carpi radialis brevis ECRL - extensor carpi radialis longus EPB - extensor pollicis brevis APL. Tendons are fibrous cords similar to a rope and are made of collagen.

The extensor tendons at the level of the wrist are divided into six extensor compartments that are designated by Roman numerals from lateral to medial 1. Cross-section of the right wrist at Listers tubercle demonstrating the anatomy of the extrinsic tendons of the hand and wrist. It attaches to the base of the second and third hand bones.

Two of the largest ligaments of the wrist are the medial ulnar and lateral radial collateral ligaments. Figure 2 shows a cross-sectional diagram of the extensor compartments. Tendon tissue that attaches a muscle to other body parts usually bones.

The bones ligaments and structures around your wrist and hand form an anatomical tunnel. The MCL passes from the distal end of the ulnar and crosses the wrist to attach to the triquetrum and the pisiform. This tendon is one of two tendons that bend the wrist.

Extensor Carpi Radialis Longus. It also attaches to the one of the wrist bones the trapezium. The carpal tunnel is an anatomical structure in your wrist and hand that protects the median nerve and several tendons.

On average the wrist bends at an angle of 30 to 35 degrees backward during extension and 5 to 10 degrees forward during flexion in everyday wrist movements. Tendon sheaths and bursae of right hand and wrist. Extensor pollicis brevis abductor pollicis longus II.

Your wrist is made up of eight small bones called the carpal bones or the carpus.
