A plane joint (arthrodial joint, gliding joint, plane articulation) is a synovial joint which, under physiological conditions, allows only gliding movement. Plane joints permit sliding movements in the plane of articular surfaces. The opposed surfaces of the bones are flat or almost flat, with movement limited by their tight joint capsules ...
The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometacarpal (TMC) joint, differs significantly from the other four CMC joints and is therefore described separately.
Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.
In human anatomy, the main role of the carpal bones is to articulate with the radial and ulnar heads to form a highly mobile condyloid joint (i.e. wrist joint), [1] to provide attachments for thenar and hypothenar muscles, and to form part of the rigid carpal tunnel which allows the median nerve and tendons of the anterior forearm muscles to be ...
Plane joints (or gliding joint) carpals of the wrist, acromioclavicular joint: These joints allow only gliding or sliding movements, are multi-axial such as the articulation between vertebrae. Hinge joints: elbow (between the humerus and the ulna) These joints act as a door hinge does, allowing flexion and extension in just one plane, i.e ...
The joints are: In the wrist there is the radiocarpal joint between the radius and carpus. Between the carpal bones are the intercarpal articulations and the midcarpal joint. The carpometacarpal joint connects the carpal bones to the metacarpus or metacarpal bones which are joined at the intermetacarpal articulations.
He had bandages under his left eye and on his left wrist. Medical personnel were seen leaving McConnell's office just after 2 p.m. Tuesday following Senate Republicans' weekly lunch.
The wrist is perhaps the most complicated joint in the body. It permits movements in two planes - extension/flexion, ulnar deviation/radial deviation - and allows complex patterns of motion under significant strain. Optimal wrist function requires stability of the carpal components in all joint positions under static and dynamic conditions.
