What is Extensor indicis muscle? The extensor indicis is a long, narrow muscle in the forearm’s posterior compartment. It has a place with the profound extensors of the lower arm, along with the supinator, abductor pollicis longus, extensor pollicis longus, and extensor pollicis brevis muscles. By applying deep pressure with the index finger extended over…
What is Extensor carpi radialis longus muscle? The extensor carpi radialis longus is the name of an extensor muscle in the posterior compartment of the forearm. Depending on where they are, all forearm muscles can be divided into groups (radial and ulnar) and layers (superficial to deep). The Extensor Carpi Radialis is arranged as follows:…
What is Extensor carpi ulnaris muscle? The extensor carpi ulnaris muscle is a muscle located in the forearm that extends from the lateral epicondyle of the humerus (a bony prominence on the outside of the elbow) and the posterior border of the ulna (one of the two bones in the forearm) to the base of…
What is the Extensor digitorum muscle? The extensor digitorum is a long muscle in the posterior compartment of the forearm. It is one of the lower arm’s shallow extensors, alongside the brachioradialis, extensor carpi radialis longus, brevis, extensor carpi ulnaris, and extensor digiti minimi. These muscles are easily felt in the lateral aspect of the…
What is flexor carpi radialis? The Flexor carpi radialis muscle is a long, slender muscle located in the forearm. It has a fusiform shape and runs from the medial epicondyle of the humerus (upper arm bone) and the common flexor tendon to the base of the second and third metacarpal bones in hand. The muscle…
What is Flexor digitorum profundus muscle? The fusiform muscle known as the flexor digitorum profundus can be found deep within the forearm’s anterior (flexor) compartment. It makes up the deep flexor portion of the forearm, along with the pronator quadratus and flexor pollicis longus muscles. This muscle runs from the ulna’s proximal end to the…
What is Flexor pollicis longus muscle? The forearm’s flexor pollicis longus is a long muscle, as its name suggests. Along with the pronator quadratus and flexor digitorum profundus, it is a member of the deep flexors of the forearm. The flexor pollicis longus, which is located in the forearm but is inserted into the hand,…
What is the Flexor digitorum superficialis muscle? The largest muscle in the forearm’s anterior compartment is the flexor digitorum superficialis. Along with the pronator teres, flexor carpi radialis, flexor carpi ulnaris, and palmaris longus, it is a member of the forearm’s superficial flexors. This muscle is alternatively categorized as a distinct middle/intermediate layer of the…
What is Palmaris longus? The Palmaris longus is a long muscle of the foremost lower arm. It can be absent in 10% of people, but it runs from the distal humerus to the hand’s root. Along with the pronator teres, flexor carpi ulnaris, flexor carpi radialis, and flexor digitorum superficialis muscles, the Palmaris longus has…
What is the Pronator Quadratus muscle? The quadrangular, short, flat, and thin muscle known as the pronator quadratus is located in the forearm’s anterior compartment. Along with the flexor digitorum profundus and the flexor pollicis longus, it is a member of the deep group of forearm flexors. The forearm flexors’ superficial group covers these three…
