  1.  (os scaphoideum) is a boat-shaped bone (Gr. skaphoidis, boat) located on the lateral (thumb) side of the carpus (wrist). It articulates with the distal end of the radius bone.

  1. image descriptionPisiform bone (os pisiforme) is a small, pea-shaped bone that articulates with the triquetral bone on the ulnar side of the carpus (L. pisum, pea + forma, shape). It is embedded in the tendon of the flexor carpi ulnaris muscle (= sesamoid bone) and increases tension during muscle contraction.

  1. image descriptionTrapezium bone (os trapezium) is an irregular-shaped bone located distal to the scaphoid bone on the lateral (thumb) side of the carpus (Gr, tetrapeza, object with four feet). It is the radial (lateral) border of the carpal tunnel, and its distal surface articulates with the proximal surface of the first metacarpal (thumb) bone.

  1. image descriptionTrapezoid bone (os trapezoideum) is a small, four-sided bone that is wedged between the trapezium and capitate bones (Gr. trapezoid, a four-sided figure with two parallel sides). It articulates with the proximal end of the second metacarpal bone.

  1. image descriptionCapitate bone (os capitatum) is located medial to the trapezium in the center of the distal row of the carpus. The name of the bone is based on its rounded proximal head (L. caput, head), which fits into the concavities of scaphoid and lunate bones. Distally, the capitate bone articulates with the proximal end of the third metacarpal bone.

  1. image descriptionHamate bone (os hamatum) is located on the ulnar side of the carpus. Projecting from its palmar surface is a hook-like process that forms the ulnar (medial) border of the carpal tunnel (L., hamat, hooked). The hamate bone articulates distally with the fourth and fifth metacarpal bones.

Metacarpal Bones (Metacarpus)

  1. image descriptionMetacarpals I - V  (ossa metacarpi) are the bones that support the palm of the hand. Each consists of a elongated body (shaft), cuboid base, and convex head. The bases articulate with the distal row of the carpus and the heads articulate with the proximal phalanges. Each bone is assigned a number from 1 to 5, starting on the lateral side (thumb side) of the hand.

Phalanges

The phalanges (singular: phalanx) are the fourteen bones that support the fingers or digits of the hand (ossa digitorum manus). Each finger is supported by three phalanges, exception of the thumb, which is supported by two.

  1. image descriptionProximal: I - V (os phalanx proximalis) are the phalanges located directly anterior to metatarsal bones. The proximal phalanges articulate anteriorly with the middle phalanges, except the first proxmial phalanx, which articulates with first distal phalanx.
