langman medical embriology 12 th edition

Every student will be affected by pregnancy, either their mother’s, since what happens in the womb does not, necessarily, stay in the womb, or by someone else’s.

As health care professionals you will often encounter women of childbearing age who may be pregnant, or you may have children of your own, or maybe it is a friend who is pregnant. In any case, pregnancy and childbirth are relevant to all of us, and unfortunately, these processes often culminate in nega tive outcomes.

For example, 50% of all embryos are spontaneously aborted. Further more, prematurity and birth defects are the leading causes of infant mortality and major contributors to disabilities. Fortunately, new strategies can improve pregnancy outcomes, and health care professionals have a major role to play in implementing these initiatives.

the developing human – clinically oriented embryology 8th edition

Human development is a continuous process that begins when an oocyte (ovum) from a female is fertilized by a sperm(spermatozoon) from a male.Cell division, cell migration, programmed cell death, differentiation, growth, and cell rearrangement transform the fertilized oocyte, a highly specialized, totipotent cell, a zygote, into a multicellular human being.

Although most developmental changes occur during the embryonic and fetal periods, important changes occur during later periods of development: infancy, childhood, adolescence, and earlyadulthood Development does not stop at birth. Important changes, in addition to growth, occur after birth (e.g., development of teeth and female breasts).

BRS – Embryology fifth edition

The fifth edition of BRS Embryology has afforded me the opportunity to further fine- tune a work that was already a highly rated course review book as well as an excellent review for the USMLE Step 1. This fine-tuning is a result of the many students who have contacted me by e-mail to point out errors and give suggestions for improvement. I appreciate this student feedback very much.

In the fifth edition, I have placed clinical images closer to the corresponding text to make reviewing more efficient. As in the previous edition, the Comprehensive Examination at the end of the book reflects the USMLE Step 1 format.
I hope that students will continue to find BRS Embryology a clear and thorough review of embryology.

After taking the USMLE Step 1, I invite you to e-mail me at to convey any comments or to indicate any area that was particularly represented on the USMLE Step 1, so that future editions of this book may improve.

The ninth edition of Langman’s Medical Embryology adheres to the tradition established by the original publication it provides a concise but thorough description of embryology and its clinical significance, an awareness of which isessential in the diagnosis and prevention of birth defects. Recent advances in genetics, developmental biology, maternal-fetal medicine, and public health have significantly increased our knowledge of embryology and its relevance. Because birth defects are the leading cause of infant mortality and a major contributor to disabilities, and because new prevention strategies have been developed, understanding the principles of embryology is important for health care professionals.

To accomplish its goal, Langman’s Medical Embryology retains its unique approach of combining an economy of text with excellent diagrams and scanning electron micrographs. It reinforces basic embryologic concepts by providing
numerous clinical examples that result from abnormalities in developmental processes. The following pedagogic features and updates in the ninth edition help facilitate student learning.
