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…
Description The flexor digitorum profundus muscle is a deep muscle situated in the forearm. It is one of the muscles responsible for flexing the fingers. The muscle originates from the ulna bone and interosseous membrane in the forearm and passes through the carpal tunnel before dividing into 4 tendons that insert into the distal phalanges…
Description The Flexor Carpi Radialis muscle is a long, narrow muscle located in the forearm, on the thumb side. It originates from the medial epicondyle of the humerus and the adjoining ridge of the ulna bone and then travels down the forearm to insert into the base of the second metacarpal bone of the hand….
Description The pronator quadratus muscle is a deep muscle located in the forearm, on the anterior aspect of the distal forearm bones. It is a square-shaped muscle that originates from the anterior surface of the distal quarter of the ulna bone (the medial bone of the forearm) and inserts onto the anterior surface of the…
Description The flexor digitorum superficialis (FDS) is a muscle located in the forearm that plays an important role in flexing the fingers. It originates from the medial epicondyle of the humerus (upper arm bone) and the coronoid process of the ulna (one of the forearm bones) and runs down the forearm, attaching to the middle…
Description The brachioradialis muscle is a muscle located in the forearm that acts as a flexor of the elbow joint. It is named for its origin at the brachium, or arm, and its insertion at the radius bone of the forearm. The brachioradialis muscle is a relatively small muscle compared to other muscles in the…
