Extensor Indicis Muscle Anatomy Extensor indicis is a narrow, elongated muscle found in the posterior compartment of the forearm. It belongs to the deep extensors of the forearm. Together with supinator, abductor pollicis longus, extensor pollicis longus, and extensor pollicis brevis muscles, it causes the extension of the wrist and fingers. It can be palpated…
Extensor Pollicis Longus Muscle Anatomy The extensor pollicis longus (EPL) is a thin muscle of the forearm that belongs to the posterior muscle group, lying in the second or deep layer. The extensor pollicis longus (EPL) muscle is an extrinsic thumb muscle that adducts and extends the thumb’s metacarpophalangeal (MCP) and interphalangeal (IP) joints. It…
Extensor pollicis brevis ( EPB) Muscle Anatomy Extensor pollicis brevis (EPB) is one of the muscles of the deep layer of the posterior compartment of the forearm. Along with extensor pollicis longus, it is responsible for extension of the thumb. Along with abductor pollicis longus it passes through the 1st extensor compartment of the wrist….
Abductor Pollicis Longus (APL) Muscle Anatomy The Abductor pollicis longus muscle lies immediately below the supinator and is sometimes united with it. It is found in the posterior compartment of the forearm. It is one of the five deep extensors in the forearm, along with the supinator, extensor pollicis brevis, extensor pollicis longus, and extensor…
Supinator Muscle Anatomy Supinator is a spiral muscle contained in the posterior compartment of the forearm, along with the brachioradialis, and the superficial and deep forearm extensors. It curls around the proximal part of radius, connecting it with the ulna. In doing so, the muscle crosses the sagittal axis of the forearm causing the supination…
Extensor carpi ulnaris Muscle Anatomy Extensor carpi ulnaris is a fusiform muscle in the posterior forearm. It spans between the elbow and the base of the little finger. Like all the muscles of this compartment, the extensor carpi ulnaris works as an extensor of the wrist. Moreover, due to its specific course, this muscle also…
Extensor digiti minimi Muscle Anatomy Extensor digiti minimi is a long, thin muscle found in the posterior forearm. It extends from the distal humerus to the fifth digit. Together with anconeus, brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, and extensor carpi ulnaris, it is a member of the superficial forearm extensor…
Extensor digitorum Muscle Anatomy The extensor digitorum is a long muscle located in the posterior compartment of the forearm. Together with extensor carpi ulnaris and extensor digiti minimi, it comprises the group of superficial extensors of the forearm. These muscles can be easily palpated in the lateral aspect of the posterior forearm, especially during the…
