> >
 * ====sex hormones (estrogen and progesterone) spike up --> induces ovulation process====
 * ====Body temperature at its highest --> fertilization period====

Human Embryonic Development

 * 1) ====__zygote:__ fertilized ovum====
 * 2) ====__embryo:__ an unborn or unhatched offspring in the process of development====
 * 3) ====__morula:__ solid ball of cells resulting from division of a fertilized ovum====
 * 4) ====__blastula:__ a solid ball of cells that is hollow on the inside====
 * 5) ====__gastrula:__ a hollow cup-shaped structure that have three layers of cells====
 * 6) ====__neurula:__ an embryo at the early stage of development in which neurulation occurs====
 * ====__gastrulation:__ the process in which a gastrula develops from a blastula by the inward migration of cells====
 * ====__neurulation:__ the process by which the beginnings of the vertebrate nervous system is formed in embryos====
