This study examined the anatomical and functional relationships between the abductor pollicis longus (APL) and the abductor pollicis brevis (APB) muscles. The APL has 2 divisions, a distal superficial division and a more proximal deep one.

The abductor pollicis longus (APL) muscle consists of two separate functional divisions with separate insertions. The muscle is composed of a deep and a superficial division. The APL and the abductor pollicis brevis (APB) are discussed in relation to assessment and clinical conditions on the basis o …
