- Flexor carpal radialis muscle.
- Flexor carpal ulnaris muscle.
- Flexor digitorum profundus muscle.

What is the flexor tendon sheath?
The flexor tendon sheath in the fingers is a synovial-lined, fibroosseous tunnel with segmental condensations of fibrous tissue. These fibrous bands or pulleys are: (1) the palmar aponeurosis pulley (formed by the transverse fibers of the palmar aponeurosis), (2) five annular pulleys, and (3) three cruciform pulleys.
