Document Summary

Physical growth, maturation, and aging: both genetic and extrinsic factors combine to in uence growth and aging. Patterns that hold for all humans: speci city. Prenatal development: early development is controlled by genes. Growth begins when an ovum and sperm fuse to produce a zygote: the embryo or fetes is sensitive to extrinsic facts i. e. abdominal pressure, viruses, etc. Embryonic development: occurs at conception to 8 weeks, differentiation of cells to form speci c tissues and organs, limbs formed at 4 weeks, human form noticeable at 8 weeks (eyes, ears, nose, mouth) Fetal development: 8 weeks to birth, sex is externally recognisable at 12 weeks, continued growth by hyperplasia (cell number) and hypertrophy (cell size, growth directions: cephalocaudal and proximodistal, plasticity. Capability of taking on new functions: by 22 weeks you can see a very clear image of a baby.
