tendonswrist imagingSonography allows for rapid, cost-effective, noninvasive, and dynamic evaluation of soft tissue structures, thus representing a valuable tool for ruling out musculoskeletal disorders of the wrist. Because of the complexity of the wrist joint, sonographic training and familiarity with...
is a vital part of the human body. It provides the body with shape, stability, and protection of internal organs. It is composed of 206 bones that connect to each other via joints. Accessory structures that support the skeletal system are the cartilage, ligaments, bursae, and muscle tendons...

hand,terminal part of the forelimb in primates. The human hand consists of the wrist, palm, four fingers, and thumb. In humans and other primates, the thumb is opposable, i.e., it can be moved into a position opposite to the other four digits. Opposable thumbs make possible precise move...
(mentioned earlier). This structure lies on the palm side of the wrist. This band of tissue keeps the flexor tendons frombowingoutward when you curl your fingers, thumb, or wrist. The tendons that travel over the back of the wrist, theextensor tendons, run through a series of tunnels, ...
Extensions of the articular disk insert into all bones of the ulnar articular chain. The function of some muscles as stabilizers of the wrist by virtue of the position of their tendons was confirmed by electromyographic observations. 展开
Abstract On the dorsal side of the wrist, the extensor tendons run within six compartments, numbered from 1 to 6, from the radial to the ulnar side. The first compartment consists of the abductor pollicis longus and extensor pollicis brevis tendons. The second comprises the doi...
