Upper palmar creases. The hands shown in Fig. 6 demonstrate the effect of specific hand malformations on the formation of the transverse palmar creases. In each case the creases, though abnormal, relate to the rune-
Flexion creases are formed during early intrauterine life and, therefore, they can be influenced by factors causing aberrant de velopment of the embryo. The first major palmar crease to appear on the embryonic palm is the radial longitudinal crease that borders the thenar eminence.

The TC extends to the center of the palm along the thenar pad. In both hand and foot, the longitudinal ...
