<P> The pair of rows together form an arch which is convex proximally and concave distally . On the palmar side , the carpus is concave , forming the carpal tunnel which is covered by the flexor retinaculum . Because the proximal row is simultaneously related to the articular surfaces of the radius and the distal row , it adapts constantly to these mobile surfaces . The bones of this row - scaphoid , lunate , and triquetrum - have their individual movements . The scaphoid contributes to the stability of the midcarpus as it articulates distally with the trapezium and the trapezoid . The distal row is more rigid as its transverse arch moves with the metacarpals . </P>
