![]() superficialis tendons, which pass through the palm side of the wrist and hand, and attach at the bases of the middle phalanges.Tendons are bands of connective tissue that attach the muscles to the bone enabling the muscles to move the bones. ulnocarpal and radioulnar ligaments – two sets of ligaments that provide the main support for the wrist.dorsal radiocarpal ligaments – ligaments that support the back of the wrist.volar radiocarpal ligaments – a complex web of ligaments that support the palm side of the wrist.radial and ulnar collateral ligaments – a pair of ligaments which bind the bones of the wrist and provide stability.As the joint in the finger is straightened, this ligament tightens to keep the PIP joint from bending backward. volar plate – a ligament that connects the proximal phalanx to the middle phalanx on the palm side of the joint.collateral ligaments – strong ligaments on either side of the finger and thumb joints, which prevent sideways movement of the joint.The ligaments are tough bands of connective tissue that connect the bones to support them and keep them in place. The joints are enclosed by a fibrous capsule that is lined with a thin membrane called the synovium, which secretes a fluid to lubricate the joints. The surfaces of the bones where they meet to form joints are covered with a layer of cartilage, which allows them to glide smoothly against one another as they move. distal interphalangeal joint (DIP) – the joint closest to the fingertip.proximal interphalangeal joint (PIP) – the joint in the middle of the finger.metacarpophalangeal joint (MCP) – the joint at the base of the finger. ![]() Joints are formed wherever two or more of these bones meet. Each finger has three phalanges (the distal, middle, and proximal) the thumb has two. the phalanges (singular phalanx) – the 14 narrow bones that make up the fingers of each hand. ![]() the metacarpals – the five bones that comprise the middle part of the hand.the hamate, capitate, trapezoid and trapezium on the lower side of the hand.the pisiform, triquetrum, lunate and scaphoid on the upper end of the wrist.The carpal bones are bound in two groups of four bones: The carpus is formed from eight small bones collectively referred to as the carpal bones. ![]() Rather than a single joint, the wrist is actually made up of multiple joints where the bones of the arm and hand meet to allow movement The wrist is formed where the two bones of the forearm – the radius (the larger bone on the thumb side of the arm) and the ulna (the smaller bone on the pinky side) – meet the carpus. The following are the main structures of the hands: ![]()
