    Study Notes

    • Mitosis is a process where cells divide into two parts to reproduce themselves, resulting in two daughter cells that are genetic duplicates of the original cell.
    • Human sperm cells and ova reproduce through Meiosis, which reduces the number of chromosomes by half, producing eggs or sperm with 23 chromosomes.
    • The union of the ovum and sperm usually occurs around day 14 of the menstrual cycle in the ampulla of the fallopian tube, resulting in a zygote with 46 chromosomes.
    • Fertilization determines the gender of the baby, with the ovum carrying only an X chromosome and the sperm carrying either an X or Y chromosome.
    • Implantation of the blastocyst into the endometrium typically occurs 5-6 days after fertilization, leading to the development of the placenta and fetal structures.
    • The amniotic sac surrounding the embryo secretes fluid to form amniotic fluid, which serves multiple functions including maintaining temperature, cushioning the fetus, and providing a filtration system for waste.
    • Prenatal care includes various tests such as blood type and Rh factor, genetic background assessment, Nuchal Translucency Test, maternal serum alpha fetoprotein screening, and chorionic villus sampling to assess the health of the fetus and mother during pregnancy.
