What is the function of flexor retinaculum?
The flexor retinaculum forms a retinacular bridge over the carpal tunnel extending from ulnar to radial direction. Its main function is to protect the contained without a significant mechanical action in supporting the transverse carpal arch.
What passes through the flexor retinaculum of hand?
The flexor retinaculum is the roof of the carpal tunnel, through which the median nerve and tendons of muscles which flex the hand pass.
What is Retinacula function?

What is the function of the wrist flexor and extensor Retinaculum?
The extensor retinaculum of the wrist is the broad ligamentous sheet located at the dorsal aspect of the wrist and functions to keep the extensor tendons in alignment and prevent bowstringing during movement.
What is ankle Retinaculum?
A retinaculum is a band of thick deep fascia that holds the long tendons of your ankle (those that cross the ankle) in place. Retinaculum also acts as a pulley system increasing mechanical advantage.
What is the function of the flexor retinaculum quizlet?

What is the major function of the finger flexor pulley system?
The primary role of the flexor pulley system is to convert linear translation and force in the muscle-tendon into rotation and torque at the finger joints.
What does the flexor retinaculum of the hand do?
Flexor retinaculum of hand Flexor retinaculum is a strong fibrous band which bridges the anterior concavity of the carpal bones thus converts it into a tunnel, the carpal tunnel.
Is the flexor retinaculum a fibrous band or tunnel?
Flexor retinaculum is a strong fibrous band which bridges the anterior concavity of the carpal bones thus converts it into a tunnel, the carpal tunnel. These four bony points are all palpable in the living hand and it should be noted that pisiform is the only carpal bone that gives attachments to both flexor and extensor retinacula.
Can a flexor retinaculum cause carpal tunnel syndrome?
If the flexor retinaculum compresses the median nerve, carpal tunnel syndrome may occur. Symptoms include tingling, numbness, and pain in the wrists, hands, and forearm. Carpel tunnel syndrome may be caused by anything that leads to inflammation in the wrist.
Where is the roof of the flexor retinaculum?
The flexor retinaculum encloses and forms the roof of the carpal tunnel. The ulna aspect of the flexor retinaculum forms the floor of Guyon’s canal. It has superficial and deep layers, which are separate on the radial aspect, containing the tendon of flexor carpi radialis.
