Annular pulleys – 5 associated with each finger, 2 associated with the thumb. Cruciate pulleys – 3 associated with each finger.

For images of pathology, and detailed descriptions. The primary structures to examine are: Flexor tendons and sheaths. Tendons: Flexor pollicis longus (FPL) runs through the carpal tunnel and thenar eminence to insert on the distal phalanx. Flexor pollicis brevis forms the thenar eminence of the hand. Thumb flexor anatomy labelled.

Muscles and tendons, including the flexor and extensor groups, enable fine motor skills and grip strength, while ligaments maintain stability. This intricate design allows the hand and wrist to perform precise and powerful actions essential for daily activities. This post will review all of the anatomy of the hand and wrist.
