The developing human clinically oriented embryology free download

Almost examples include a weekly and stage-by-step clinically tailored guideline for human growth. They discuss the new embryological studies, including casesof embryogenesis, causes of birth defects, and human gene functions etc.

Advances in molecular biology, including developing groundbreaking new technologies, such as recomposing DNA and Stem Cell Management, informed clinical care knowledge. In special boxes, the clinical case presentations illustrate how principles of embryology apply to clinical methods and are suitable for planning phase 1 of USMLE.

Although most developmental changes occur during the embryonic and fetal periods, important changes occur during later periods of development: infancy, childhood, adolescence, and early adulthood Development does not stop at birth.

Important changes, in addition to growth, occur after birth e. It is customary to divide human development into prenatal before birth and postnatal after birth periods. The main developmental changes occurring before birth are illustrated in the Timetable of Human Prenatal Development Figs. Examination of the timetable reveals that the most visible advances occur during the third to eighth weeks of embryonic development.

During the fetal period, differentiation and growth of tissues and organs occur. The rate of body growth increases during this period. The following terms are commonly used in discussions of developing humans; several of these terms are used in the Timetable of Human Prenatal Development.

Most terms have Latin L. Oocyte L. The female germ or sex cells are produced in the ovaries. When mature, the oocytes are called secondary oocytes or mature oocytes. Sperm Gr. The sperm, or spermatozoon, refers to the male germ cell produced in the testes testicles. Numerous sperms spermatozoa are expelled from the male urethra during ejaculation. This cell results from the union of an oocyte and a sperm during fertilization. A zygote or embryo is the beginning of a new human being.

Gestational Age. It is difficult to determine exactly when fertilization conception occurs because the process cannot be observed in vivo within the living body.
