Embryology — Gametogenesis, Fertilization and Implantation

Embryology · Basic Sciences

How it begins

Human embryology is the branch of morphological sciences that deals with the study of the prenatal development of the individual, from the formation of gametes to birth. Traditionally it is subdivided into general embryology, which includes the processes common to every embryo during the first eight weeks of development (embryonic period itself), and special embryology...
