Extensor pollicis longus (EPL) is a long muscle located at the deep layer with extensor pollicis brevis, abductor pollicis longus, extensor indicis, and supinator muscle in the posterior compartment of the forearm.[1] It originates from the mid-third of the ulna, and interosseous membrane then courses down to the distal phalanx of the thumb.

It is one of the five deep extensors in the forearm, along with the supinator, extensor pollicis brevis, extensor pollicis longus and extensor indicis. The main action of extensor pollicis longus is extension of the thumb at the metacarpophalangeal and interphalangeal joints. Extension at the metacarpophalangeal joint occurs in synergy with extensor pollicis brevis muscle. When the thumb reaches the full extension or abduction, extensor pollicis longus can also assist in adduction of the thumb. Palpation: Palpate thenar musculature, the abductor pollicis brevis is the most superficial muscle and can be felt superficial and slightly more ulnar to the underlying opponens pollicis muscle.

The Flexor Pollicis Longus muscles moves through the hand as a tendon. It travels through the carpal tunnel which is the point connecting the palm and forearm, and goes into the thumb. This muscle is located between the two muscles which facilitate flexion of the thumb, namely the Flexor Pollicis Brevis and the Abductor Pollicis. De Quervain tenosynovitis is caused by repetitive overuse of the abductor pollicis longus and extensor pollicis brevis tendons within the first dorsal compartment of the wrist. de Quervain's tenosynovitis is caused by inflammation and swelling of the tendons of the abductor pollicis longus and extensor pollicis brevis tendons at the level of the radial styloid process.

The belly of the extensor pollicis brevis lies deep in the posterior forearm, but its distal tendon become superficial farther distally. The distal tendons of the abductor pollicis longus and extensor pollicis brevis travel together in a common synovial sheath and form the lateral border of the anatomic snuffbox.

Dr. Ebraheim’s educational animated video describes the anatomy of the Abductor Pollicis Longus.The abductor pollicis longus (APL) is an important muscle. It The extensor pollicis brevis has a similar, although reduced, function. It mainly extends the thumb at the joint where it joins the palm. In direct contrast to the extensor pollicis longus, the additional function of the extensor pollicis brevis is to abduct the first metacarpal. The abductor pollicis longus muscle is innervated by the posterior interosseous nerve, which is a continuation of the deep branch of the radial nerve after it passes through the supinator muscle. Abductor pollicis longus lies close to the radial nerve.
