"The phalanges (singular: phalanx) of the hands are the tubular bones of the fingers and thumb. The second to fifth fingers each contain a proximal, middle and distal phalanx whereas the thumb only contains a proximal and distal phalanx."
"The palmar ligaments (or volar plates) are thick bands of dense fibrous tissue that attach the metacarpophalangeal and interphalangeal joints. At the metacarpophalangeal joint, these are also united by the deep transverse ligament of the palm. Fibrous flexor sheaths bridge the palmar ligaments and attach along the proximal phalanges before surrounding the flexor digitorum profundus tendons on the distal phalanges. They form a series of annular (A1 to A5 from proximal to distal) and cruciform (C1 to C3) pulleys that surround the synovial sheath coverings of the flexor tendons. The A1, A3 and A5 pulleys arise from the volar plates; A2 and A4 arise from the periosteum on the proximal half of the proximal phalanx and the mid body of the middle phalanx respectively. C1 lies between A2 and A3, C2 between A3 and A4, and C3 between A4 and A5."
