Description Flexor digiti minimi brevis is a short intrinsic hand muscle. It corresponds to the group of muscles classified as the hypothenar muscles, together with the abductor and opponens digiti minimi. The hypothenar prominence is an extension that they developed over the tiny finger’s base. The flexor digiti minimi brevis goes from the flexor retinaculum…
The extensor carpi radialis longus muscle is one of the forearm muscles that is located on the lateral (outer) side of the forearm. It originates from the lateral epicondyle of the humerus and the supinator crest of the ulna, and inserts onto the base of the second metacarpal bone. The main function of the extensor…
Description The abductor pollicis longus muscle is a muscle located in the forearm, on the lateral side of the forearm. It is one of the muscles responsible for the movement of the thumb, specifically for abducting (moving away from the hand) and extending the thumb. The abductor pollicis longus muscle originates from the posterior surface…
Description The supinator muscle is a short, thick muscle located in the posterior compartment of the forearm, just above the wrist. It runs from the lateral epicondyle of the humerus (the bony bump on the outer elbow) to the proximal end of the radius (the smaller of the two forearm bones). The main function of…
Description The extensor indicis muscle is a narrow muscle located in the forearm, running parallel to the ulna bone. It arises from the posterior surface of the ulna and the interosseous membrane, which separates the radius and ulna bones. The muscle belly is located in the mid-forearm and inserts onto the index finger’s extensor expansion…
Description Extensor carpi radialis brevis is a fusiform muscle located in the outer part of the posterior. Anconeus, brachioradialis, extensor carpi radialis longus, extensor digitorum, extensor digiti minimi, and extensor carpi ulnaris all these are combined with ECRB and, it belongs to the superficial forearm extensor group. Crossing the elbow and wrist joints from their…
Description The extensor carpi ulnaris muscle is a muscle in the forearm that runs from the lateral epicondyle of the humerus (upper arm bone) to the base of the fifth metacarpal bone (a bone in the hand). It is responsible for extending and adducting the wrist joint. The extensor carpi ulnaris muscle is part of…
Description Extensor Digiti Minimi is a long slender skeletal muscle located in the posterior compartment of the forearm. It lies in the middle of the Extensor Digitorum and Extensor Carpi Ulnaris and is usually associated with the Extensor Digitorum. The antagonist of the muscle is the Flexor Digiti Minimi muscle. Origin of Extensor Digiti Minimi…
What is the Brachialis muscle? The brachialis (Teichmann muscle), also known as the brachialis anticus, is a muscle located in the upper arm that works as a flexion of the elbow. It is located under the biceps brachii, and a group of the region known as the cubital fossa (elbow pit). It arises from the…
Description The palmaris longus muscle is a long, thin muscle that is located in the forearm, running from the elbow to the wrist. It is a relatively small muscle that is absent in about 14% of the population. The muscle arises from the medial epicondyle of the humerus (the bony prominence on the inner side…
