Carpometacarpal joint - Wikipedia
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 ...
The Thumb Carpometacarpal Joint: Anatomy, Hormones, and …
Stability and mobility represent the functional paradox of the thumb carpometacarpal (CMC) joint. The thumb requires a breadth of motion to perform tasks that are uniquely human, from forceful grasp to fine pinch. The joint morphology of the metacarpal on the trapezium affords this functional spectrum.
Carpometacarpal Joint - Anatomy, Structure, Function
2023年7月26日 · These features make the medial 4 carpometacarpal (CMC) joints extremely stable, demonstrating a powerful association between the wrist & hand, while even delivering sufficient flexibility to allow palm cupping & object holding while thumb opposition actions.

The carpometacarpal joints are the articulations between the base of the metacarpals with the distal row of carpal bones, i.e., the trapezium, trapezoid, capitate, and hamate. The first carpometacarpal joint, or the carpometacarpal joint of the thumb, is a saddle (or sellar) synovial joint that allows opposition of the thumb.
Carpometacarpal Joint - an overview | ScienceDirect Topics
The carpometacarpal joint is a synovial, saddle-shaped joint that serves as the articulation between the trapezium and the base of the first metacarpal (Fig. 85.4). The joint’s primary function is to optimize the pinch function of the hand.

2024年1月21日 · The CMC joint functions as a universal joint, allowing extension, flexion, adduction, and abduction motion. These movements, when combined, allow for complex thumb movements such as opposition, retropulsion, palmar and radial abduction, and adduction.
The carpometacarpal (CMC) of the thumb is a saddle joint that permits a wide range of motion and is largely responsible for the characteristic dexterity of human prehension. This joint, located at the very base of the thumb, is subject to large physical stresses throughout life.

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.
Carpometacarpal Joints - (Anatomy and Physiology I) - Fiveable
The carpometacarpal joints are a series of synovial joints located between the distal row of carpal bones and the proximal ends of the metacarpal bones in the hand. These joints facilitate the complex movements and flexibility required for dexterous hand function.
