In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges and the carpal bones (wrist bones), which articulate with the forearm. The metacarpal bones are homologous to the metatarsal bones in the foot.
The joints in the hand are joints found at the distal end of the upper limb.. 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.

In a case where there is localized tenderness within the snuffbox, knowledge of wrist anatomy leads to the speedy conclusion that the fracture is likely to be of the scaphoid. This is understandable as the scaphoid is a small, oddly shaped bone whose purpose is to facilitate mobility rather than confer stability to the wrist joint [citation ...
There are a total of 64 bones in the arms, 32 in each arm Upper arm bones (6 bones in total; 3 on each side) Humerus (2) Pectoral girdle (shoulder) Scapula (2) Clavicle (2) Lower arm bones (4 bones in total, 2 on each side) left bone Ulna (2) (Lined up with pinky) Radius (2) (Lined up with thumb) Hand (54 bones in total; 27 in each hand) Carpals
In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; [1] [2] (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus [2] and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of ...
In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those of the metacarpus do. The corresponding part of the foot is the tarsus. The carpal bones allow the wrist to move and rotate ...
Biceps is the major supinator (drive a screw in with the right arm) and pronator teres and pronator quadratus the major pronators (unscrewing) — the latter two role the radius around the ulna (hence the name of the first bone) and the former reverses this action assisted by supinator. Because biceps is much stronger than its opponents ...
