Изображения

Описание

The heads of phalanges (distal extremities) are smaller than the proximal, and each ends in two condyles (trochlea of phalanx) separated by a shallow groove; the articular surface extends farther on the volar than on the dorsal surface, a condition best marked in the bones of the first row.
