Embriology
Cell division
Mitosis
mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division
Meiosis
Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
Organogenesis
What is it?
organogenesis, in embryology, the series of organized integrated processes that transforms an amorphous mass of cells into a complete organ in the developing embryo. The cells of an organ-forming region undergo differential development and movement to form an organ primordium, or anlage.
Types of it
The three germ layers are the endoderm, the ectoderm, and the mesoderm. Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body.
Fetogenesis
The phase of prenatal development from the 9th week to birth; it entails the growth and differentiation, particularly functional differentiation, of the conceptus after embryogenesis is completed
: 
Fertilization
Fertilisation or fertilization, also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development

Embriogenesis
Embryogenesis is the process of embryo formation and development. This process is the stage of cell development after experiencing fertilization or fertilization. Embryogenesis includes cell division and regulation at the cellular level. Cells in embryogenesis are referred to as embryogenic cells.
