It is the smallest bone in the distal row. It may be known by its wedge-shaped form, the broad end of the wedge constituting the dorsal, the narrow end the palmar surface; and by its having four articular facets touching each other, and separated by sharp edges. It is homologous with the 'second distal carpal' of reptiles and amphibians. The etymology derives from the Greek trapezion which means 'irregular quadrilateral,' from tra- 'four' and peza 'foot' or 'edge. ' Literally, 'a little table' from trapeza meaning 'table' and -oeides 'shaped.[Wikipedia:Trapezoid_bone] EMAPA:36174 AAO:0000848 distal carpal 2 lesser multangular bone lesser multangular FMA:23724 UMLS:C0223741 distal carpal bone 2 manus distal carpal bone 2 distal carpal bone manus bone
