Learn about fertilization and how chromosomes determine the gender and physical attributes of a baby. We show how a single cell develops into an embryo and follow the rapidly changing stages of fetal development. Students also examine the importance of prenatal care, nutrition and a healthy prenatal environment.
This program traces the development of a human being from conception to full-term fetus, with a focus on the functions of the male and female reproductive systems. The three stages of development in the womb—pre-embryonic, embryonic, and fetal, generated by the mechanisms of division, differentiation, morphogenesis, patterning, and growth—are illustrated, after which there is a close examination of male and female puberty—the maturation of the reproductive system and the beginning of human sexual response.
This highly technical program designed for advanced anatomy courses and health-care practitioners focuses on the processes that lead to normal impregnation, and the physical hindrances that can prevent it. The various fertilization techniques illustrated include synthetic stimulation of hormones, in vitro fertilization, micro-insemination, and test-tube embryo transfer to the womb. How diseases of the uterine lining and OAT syndrome can disrupt impregnation is discussed and illustrated.
