Palmar Intercarpal Ligaments
The palmar intercarpal ligaments are fibrous bands that extend transversely across the palmar surfaces of the carpal bones, connecting adjacent carpals. These are the ligaments that define the structure of the ligamentous palmar arch. See also * Palmar carpal ligament * Pisohamate ligament * Pisometacarpal ligament The pisometacarpal ligament joins the pisiform to the base of the fifth metacarpal bone. It is a continuation of the tendon of the flexor carpi ulnaris The flexor carpi ulnaris (FCU) is a muscle of the forearm that flexes and adducts at the wrist ...

Wrist
In human anatomy, the wrist is variously defined as (1) the Carpal bones, carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; "The wrist contains eight bones, roughly aligned in two rows, known as the carpal bones." (2) the wrist joint or radiocarpal joint, the joint between the radius (bone), radius and the Carpal bones, carpus and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as ''wrist joints''. "With the large number of bones composing the wrist (ulna, radius, eight carpas, and five metacarpals), it makes sense that there are many, many joints that make up the structure known as the wrist." This region also includes the carpal tunnel, the anatomical snuff box, bracelet lines, the Flexor retinaculum of the hand, flexor retinaculum, and the ex ...

Carpal
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 καρπός (karpós), meaning "wrist". In human anatomy, the main role of the wrist is to facilitate effective positioning of the hand and powerful use of the extensors and flexors of the forearm, and the mobility of individual carpal bones increase the freedom of movements at the wrist.Kingston 2000, pp 126-127 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 vertically. Structure Bones The eight carpal bones may be conceptually organized as either two transverse rows, or three longitudinal columns.

Palmar Carpal Ligament
The palmar carpal ligament (also volar carpal ligament or ''Guyon's Tunnel'') is the thickened portion of antebrachial fascia on the anterior of the wrist. It is officially unnamed.Moore, Keith L., Arthur F. Dalley II: ''Clinically Oriented Anatomy'', 4th ed. Lippincott, Williams & Wilkins,1999. The palmar carpal ligament is a different structure than the flexor retinaculum of the hand, but the two are frequently confused. The palmar carpal ligament lies superficial and proximal to the flexor retinaculum. The ulnar nerve and the ulnar artery run through the ulnar canal, which is deep to the palmar carpal ligament and superficial to the flexor retinaculum. The palmar carpal ligament is continuous with the extensor retinaculum of the hand, which is located on the posterior side of the wrist.

Pisohamate Ligament
The pisohamate ligament is a ligament in the hand. It connects the pisiform to the hook of the hamate. It is a prolongation of the tendon of the flexor carpi ulnaris. It serves as part of the origin for the abductor digiti minimi. It also forms the floor of the ulnar canal, a canal that allows the ulnar nerve and ulnar artery The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspects of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial ar ... into the hand.

Pisometacarpal Ligament
The pisometacarpal ligament joins the pisiform to the base of the fifth metacarpal bone. It is a continuation of the tendon of the flexor carpi ulnaris The flexor carpi ulnaris (FCU) is a muscle of the forearm that flexes and adducts at the wrist joint. Structure Origin The flexor carpi ulnaris has two heads; a humeral head and ulnar head. The humeral head originates from the medial epicondyle o ....
