Dorsal view of the forearm and the interspace between extensor digitorum and extensor carpi radialis brevis are unclear at middle segments and proximal parts of forearm, but gradually became evident at the distal parts of forearm; whereas abductor pollicis longus
and extensor pollicis brevis emerged superficially from the interspace between extensor digitorum and extensor carpi radialis brevis at the 1/3 juncture of the middle and distal segments of forearm, thereby indicating extensor carpi radialis brevis and extensor digitorum and abductor pollicis longus
et al (1) in 1988 have seen the APL tendon to divided in three slips, Mehta V et al (5) in (2009) observed the quadruplicate arrangement of abductor pollicis Longus
tendon and found 3 slips of APL.
1= ex- tensor carpi radialis longus muscle; 2= ex- tensor carpi radialis brevis muscle; 3= tendon of the extensor carpi radialis longus muscle; 4= tendon of the extensor carpi radialis brevis muscle; 5= abductor pollicis longus
(3,4) It is usually caused by overuse or an increase in repetitive activity, resulting in shear microtrauma from repetitive gliding of the first dorsal compartment tendons (abductor pollicis longus
or APL, and extensor pollicis brevis or EPB) beneath the sheath of the first compartment over the styloid of the radius leading to thickening of the extensor retinaculum of the wrist (and not related to inflammation as was once thought).
The extrinsic musculature of the thumb consists of the flexor pollicis longus (FPL), innervated by the anterior interosseous nerve, and the extensor pollicis longus (EPL), extensor pollicis brevis (EPB), and the abductor pollicis longus
(APL), all innervated by the posterior interosseous nerve.
1), is laterally limited by the tendons of abductor pollicis longus
and extensor pollicis brevis muscles, and medially limited by the tendon of extensor pollicis longus muscle (Latarjet & Ruiz-Liard).
After passing deep to the abductor pollicis longus
and extensor carpi radialis brevis the radial artery reaches the anatomical snuff box where its become a content of it.

The origins of the extensor indicis, extensor pollicis longus, extensor pollicis brevis, abductor pollicis longus
, flexor pollicis longus, and flexor digitorum profundus were digitized from 11 cadavers.
