The common extensor tendon serves as the upper attachment (in part) for the superficial muscles that are located on the posterior aspect of the forearm: Extensor carpi radialis brevis; Extensor digitorum; Extensor digiti minimi; Extensor carpi ulnaris [1] [2]
The forearm is the region of the upper limb between the elbow and the wrist. [1] The term forearm is used in anatomy to distinguish it from the arm , a word which is used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm.
The tendon of the flexor carpi radialis is visible on the anterior surface of the forearm, just proximal to the wrist, when the wrist is flexed. It is the tendon seen most lateral, closest to the thumb.
On the back of the hand, the ED tendons diverge to follow the fingers and the EI tendon joins the ulnar side of one of the ED tendons along the back of the index finger. The EDM takes a similar course as the EI except it follows the ED tendon along the little finger. The ECU crosses from the lateral to the medial side of the forearm.
De Quervain's syndrome is a medical condition when the synovial sheath surrounding tendons in the first extensor tendon compartment becomes inflamed, so called tenosynovitis. [12] The tendons of the abductor pollicis longus and the extensor pollicis brevis run narrower due to the thickening of the synovial sheath, which causes pain when ...
The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. [1] [2] It is also capable of both pronation and supination, depending on the position of the forearm. [2] It is attached to the distal styloid process of the radius by way of the brachioradialis tendon, and to the lateral supracondylar ridge of the humerus.
The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1] brachioradialis; extensor carpi radialis brevis; extensor carpi radialis longus; It is also sometimes known as the "wad of three", [2] "lateral compartment", [3] or "radial group" [4] of the forearm.
The tendon of flexor carpi ulnaris can be seen on the anterior surface of the distal forearm. On a person's distal forearm, just before the wrist, there are either two or three tendons. The tendon of the flexor carpi ulnaris is the most medial (closest to the little finger) of these.
