PSYB20H3 Lecture Notes - Lecture 3: Small For Gestational Age, Miscarriage, Complications Of Pregnancy
Document Summary
350 different types: focus of research in regenerative research, cell death, termed apoptosis or cell suicide, normal part of the developmental process. Example: hand development: principles of growth, gestation: prenatal period of development between conception and birth. Clara rebello: normal range is between 37 and 41 weeks, stages of prenatal development, germinal, embryonic, fetal, the germinal stage. Includes the first two weeks of development: the zygote divides and becomes more complex, cells arrange into a hollow sphere, with the inner cell mass. Implantation then occurs occurs when the zygote embeds itself in the uterine lining: successful implantation only takes place approx. Identical- result from the splitting in half of the zygote: resulting in two zygotes with the same genetic makeup, fraternal- result when two eggs are released into the fallopian tube at the same time. Clara rebello: no more alike genetically than siblings, teratogens: environmental agents which can interfere with normal prenatal development, organogenesis, timing, dose, duration.
