Abstract

Fetal hand morphogenesis was studied between 6 and 14 weeks of gestation by scanning electron microscopy. Detailed observations of surface features allowed three individualized phases of hand development to be distinguished, related to the shape (6 to 10 weeks), to the appearance of creases (10 to 13 weeks) and of ridges (13 weeks onwards).

      Then, phagocytosis removes the disintegrated cells (Al-Qattan 2014; Raszewski and Singh 2021). Hand shape is complete between the 6th and 10th week, and the creases from the 10th to 13th week; then digital pads and ridges begin to form (Lacroix et al. 1984) (Figs. 4 and 5). Limb growth proceeds along three axes: proximal–distal, anterior–posterior (radio–ulnar) and dorsal–ventral.

      This is largely because dermatoglyphic patterns genetically determined are heritable and is believed to follow a polygenic pattern of inheritance.5 Epidermal ridges laid down between tenth and eighteenth weeks of gestation remain unchanged except for increase in size.6–8 However, it had been previously observed that in spite of the pivotal role of genes in determining dermatoglyphic expression, some aspects of dermatoglyphic variabilities are determined by such environmental factors as radiation drugs and hormones.9,7
