The tendons of the APL and EPB indicate the lateral (anterior) boundary of the anatomical snuff box, and the tendon of the EPL indicates the medial (posterior) boundary of the box. The radial artery crosses the floor of the snuff box, where its pulsations may be felt. The scaphoid and, less distinctly, the trapezium are palpable in the floor of the...

It runs deep to the extensor tendons. The radial pulse can be palpated in some individuals by placing two fingers on the proximal portion of the ...
The three muscles acting on the thumb (APL, EPB, and EPL) are deep to the superficial extensors and emerge (“crop out”) from a furrow in the lateral part of the forearm that divides the extensors. Because of this characteristic, they are referred to as outcropping muscles. The tendons of the APL and EPB bound the triangular anatomical snuff box lat...

If localized pain is reported in the anatomical snuffbox, a fracture of the scaphoid is the most likely cause.Th...
