Extensor carpi radialis brevis works together with extensor carpi ulnaris and extensor carpi radialis longus to extend the hand at the wrist joint. This action is vital in a sequence of muscle contractions needed for clenching a fist or making a grip. When performing these functions, wrist extension blocks the flexor muscles from on acting upon. The partially obscured extensor carpi radialis brevis is shown in blue. In human anatomy, extensor carpi radialis brevis is a muscle in the forearm that acts to extend and abduct the wrist. It is shorter and thicker than its namesake extensor carpi radialis longus which can be found above the proximal end of the extensor carpi radialis brevis.

Description. Extensor carpi radialis brevis (ECRB) is a short muscle emerging underneath the extensor carpi radialis longus and both muscles share a common tendinous synovial sheath [1]. It is an extensor muscle located superficially at the posterior compartment of the forearm. The extensor carpi radialis brevis is an extensor muscle in the posterior superficial compartment of the forearm.[1] It is the prime dorsiflexor of the wrist. The extensor carpi radialis brevis originates from the lateral epicondyle of the humerus by a common tendon shared with other muscles of the posterior superficial compartment, including the extensor carpi ulnaris, extensor digiti minimi. The extensor carpi radialis brevis is a muscle within the superficial compartment of the posterior forearm.Its lateral position within the forearm produces abduction as well as extension at the wrist. The tendon of the extensor carpi radialis brevis passes through the 2nd extensor compartment at the wrist.. Attachments: Originates from the lateral epicondyle of the humerus and attaches to the. The extensor carpi radialis brevis muscle is one of the muscles of the superficial part of the posterior compartment of the forearm. It is a long, fusiform type of skeletal muscle. In the middle of the forearm, the muscle belly gives rise to a flat tendon, which travels inferiorly along the lateral aspect of the forearm towards the lateral.

Extensor Carpi Radialis Brevis. Origin. Lateral epicondyle of humerus. Insertion. Base of 3rd metacarpal. Action. Extend and abduct hand at wrist joint. Innervation. Deep branch of radial nerve (C7, C8) The extensor carpi radialis brevis (ECRB) is a muscle spanning the dorsal aspect of the forearm primarily responsible for extension and abduction of the wrist. It is relevant to orthopedic surgeons for a variety of reasons, including its association with a number of common pathologies and surgical approaches. The aim of this review is to. Brachioradialis is a powerful flexor of the elbow, acting most strongly with the forearm in semipronation. Extensor carpi radialis longus (dorsal view) In contrast, both the extensor carpi radialis longus and brevis are rather poor flexors of the elbow. Their main function is the extension and abduction (radial deviation) of the wrist joint. Extensor Carpi Radialis Brevis. Origin: Lateral epicondyle of humerus Insertion: Base of 3rd metacarpal Action: Extend and abduct hand at wrist joint Innervation: Deep branch of radial nerve (C7 and C8) Arterial Supply: Radial artery

Extensor carpis radialis brevis (ECRB) muscle is a muscle of the superficial layer of the posterior compartment of the forearm . It passes through the 2 nd extensor compartment of the wrist. Extensor carpi radialis brevis muscle is one of the three muscles forming the mobile wad of Henry . It is one of the extrinsic muscles of the hand. However, the extensor carpi radialis brevis is much shorter and thicker than its longus counterpart. The muscle originates along the lateral supracondylar ridge, which is a narrow, raised region.
Lateral epicondylitis is the most common overuse disorder affecting the lateral side of the elbow. This syndrome typically presents with intense pain about the extensor origin (lateral aspect) of the elbow. The pathogenesis of this disease originates from the extensor carpi radialis brevis (ECRB) tendon, but other closely associated structures. The extensor carpi radialis brevis (Latin: musculus extensor carpi radialis brevis) is a slim and long superficial muscle of the forearm that stretches between the humerus and the third metacarpal bone.It belongs to the lateral compartment of the forearm muscles. The extensor carpi radialis brevis is the deepest muscle of the lateral forearm compartment, and it lies inferior to the extensor.
