The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those of the metacarpus do. Carpal Avascular Necrosis: A condition where a lack of blood supply to the carpal bone cells causes serious damage, finally resulting in their death. Carpel, One of the leaflike, seed-bearing structures that constitute the innermost whorl of a flower. the bowl-shaped and c-shaped carpal bone. Due to their position in the hand, the carpal bones often get fractured or dislocated as a result of accidents, like falling on an outstretched hand , and sports injuries, especially when playing sports like hockey and tennis. Recent Examples on the Web: Adjective Jackson, who graduated from Thompson High School in Alabaster, was a coal miner and a welder but had recently been out of work because of neuropathy, arthritis and carpal tunnel in his hands. Carpometacarpal Joints: Those connecting the metacarpals and the distal carpal bones. Occasionally accessory bones are found in the carpus, but of more than 20 such described bones, only four (the central, styloid, secondary trapezoid, and secondary pisiform bones) are considered to be proven accessory bones. (See Decapod anatomy), The Latin word "carpus" is derived from Greek καρπὁς meaning "wrist". The pisiform bone is somewhat unusual, in that it first appears in primitive reptiles, and is never found in amphibians. From the straight position two pairs of movements of the hand are possible: abduction (movement towards the radius, so called radial deviation or abduction) of 15 degrees and adduction (movement towards the ulna, so called ulnar deviation or adduction) of 40 degrees when the arm is in strict supination and slightly greater in strict pronation. The proximal carpals are referred to as the radiale, intermediale, and ulnare, after their proximal articulations, and are homologous with the scaphoid, lunate, and triquetral bones respectively.

There are eight carpal bones in the human wrist, each one being named according to their shape: The capitate is the largest of all the carpal bones . The capitate is a carpal bone located in the most central portion of the wrist. The bones meet and articulate on a nearly flat surface, and they need to glide past the adjacent bones in different directions during movement . Flexion is the downward movement of the wrist while the extension is the backward movement; Rotation of the forearm consists of supination and pronation movements. Carpals articulate distally (see DISTAL with the METACARPALS. tarsals. Carpals definition anatomy.

The root "carp-" translates to "pluck", an action performed by the wrist. For example, the scaphoid contributes to midcarpal stability by articulating distally with the trapezium and the trapezoid. 29 The manus has a complex anatomy that is well documented and studied. , Dorsiflexion is produced by (in order of importance) extensor digitorum, extensor carpi radialis longus, extensor carpi radialis brevis, extensor indicis, extensor pollicis longus, and extensor digiti minimi. b. Because many tetrapods have less than five digits on the forelimb, even greater degrees of fusion are common, and a huge array of different possible combinations are found. The term "carpus" is derived from the Latin carpus and the Greek καρπός (karpós), meaning "wrist". The radioscaphocapitate and the long and short radiolunate ligaments joint the radius with various carpal bones.

Almost all mammals and reptiles, for example, have lost the fifth distal carpal, and have only a single centrale - and even this is missing in humans. The formation of these centers roughly follows a chronological spiral pattern starting in the capitate and hamate during the first year of life. Palmar flexion is produced by (in order of importance) flexor digitorum superficialis, flexor digitorum profundus, flexor carpi ulnaris, flexor pollicis longus, flexor carpi radialis, and abductor pollicis longus. gripping the bone between the thumb and index finger). the proximal row of four bones, medial to lateral incluid the scaphoid, lunate, triquetral and pisiform bones. , Combined with movements in both the elbow and shoulder joints, intermediate or combined movements in the wrist approximate those of a ball-and-socket joint with some necessary restrictions, such as maximum palmar flexion blocking abduction.
