title: Study of arterial patterns of the hand in primates. Deep palmar arterial arches and their correlating arteries in Macaca fuscata.
abstract: Study of the arterial patterns of the hand in Macaca fuscata, especially those of the deep palmar arterial arches and their correlating arteries, by three-dimensional arteriographic analysis revealed the following: (1) The deep palmar arterial arches are formed by the perforating branches of the 2nd dorsal metacarpal artery, and they are usually composed of two proximal arches (catella volaris proximalis and arcus volaris profundus) and one distal arch (catella volaris distalis). (2) In the 3rd and 4th metacarpal interosseous spaces, the intermetacarpal arteries arise from the catella volaris proximalis, and the arcus volaris profundus has palmar metacarpal arteries which descend along the palmar side of each metacarpal bone. (3) There is a definite regularity in the formation of the intermetacarpal arteries between the catella volaris proximalis and the catella volaris distalis and of the palmar metacarpal arteries between the arcus volaris profundus and the catella volaris distalis.
