Document Summary

Identify the barriers to typical development uterine wall (8-10 days after conception). The prenatal period is a crucial time for physical, sensory, and cognitive development. Events during gestation can have profound effects on later life outcomes. Germinal period the first two weeks after the sperm and egg unite, lasts until the developing cells attach to the. Gamete a mature male (sperm) or female (ova) cell used for reproduction. Gametes are haploid (having one set of chromosomes instead of two only half the genetic complement req. for life). The merging male and female gamete creates a zygote (a single new cell formed at conception - diploid). Diploid a cell containing both sets of chromosomes. During the germinal period, the zygotic cell divides into identical copies making a spherical shape. Called cleavage (division of cells in the early embryo to form blastomeres), which begins roughly 24h after conception.
