10 Questions
What is the function of the pisiform bone in the wrist?
Acting as a pulley for flexor carpi ulnaris
Where is the articular capsule of the wrist joint attached?
Above to the lower ends of the radius and ulna, and below to the proximal row of carpal bones
What strengthens the fibrous capsule of the wrist joint?
Palmar carpal ligaments
What is the function of the palmar radiocarpal ligament?
Attaches above from the lower end of the radius and its styloid process, runs downwards and medially, and is attached below to the anterior surfaces of the scaphoid, the lunate, and triquetral bones
What lies in front of the styloid process of the ulna and in front of the articular disc in the wrist joint?
A protrusion of synovial membrane, called the recessus sacciformis
