Detailed explanation-1: -Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm-the radius and the ulna. Each finger consists of one hand bone (metacarpal ) and three finger bones (phalanges), while each thumb consists of one metacarpal bone and two phalanges.

Detailed explanation-2: -Introduction. The carpal bones are bones of the wrist that connect the distal aspects of the radial and ulnar bones of the forearm to the bases of the five metacarpal bones of the hand. There are eight carpal bones, which divide into two rows: a proximal row and a distal row.

Detailed explanation-3: -The eight carpal bones (scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, and trapezium) are arranged in two rows between the metacarpal bases distally and the distal radius and ulna (with the intervening TFCC) proximally (Fig.

Detailed explanation-4: -The carpal bones are the eight small bones that make up the wrist (or carpus) that connects the hand to the forearm. The term “carpus” is derived from the Latin carpus and the Greek (karpós), meaning “wrist".

Detailed explanation-5: -These 8 bones are named for their unique shapes; Scaphoid (boat), Lunate(Crescent), Triquetrum(3-cornered), Pisiform(pea), Trapezuim(Table), Trapezoid(quadrilateral), Capitate(head shaped), and Hamate (hook-shaped).
