Plate I. Human Embryo 4 and 4.5 weeks Lower Limb Region

Fig. 1. Embryo 2, length 7 mm., age about four weeks.

Fig. 2. Embryo 143 CLXIII, length 9 mm., age about four and a half weeks.

Two figures, repeated from this journal (Vol. 1, Plate II), to illustrate early stages in the diiferentiation of the inferior extremity.

Plate II, Fig. 1, represents the tissue differentiation in a section through the posterior limb-buds of Embryo 2. At the left the bud is shown cut through an area near the distal extremity of the coelom. At the right the cut is more dorsal and extends through the tips of the lumbar spinal nerves.

Historic Disclaimer - information about historic embryology pages

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.     (More?
