metakarpofalangalledder
Metakarpofalangalledder refers to the joints connecting the metacarpal bones of the hand to the phalanges (finger bones). These joints are crucial for hand dexterity and the ability to grip and manipulate objects. Each finger, excluding the thumb, has three phalanges: a proximal, middle, and distal phalanx. The metacarpal bone of each finger articulates with the proximal phalanx, forming the metacarpophalangeal joint. The thumb has only two phalanges, and its metacarpal articulates with the proximal phalanx to form the carpometacarpal joint, which functions similarly in this context.
These joints are synovial joints, meaning they are enclosed in a capsule filled with synovial fluid, which
