Embryology — Gametogenesis, Fertilization and Implantation

Embryology · Basic Sciences

How it begins

La embriología humana constituye la rama de las ciencias morfológicas que se ocupa del estudio del desarrollo prenatal del individuo, desde la formación de los gametos hasta el nacimiento. Tradicionalmente se subdivide en embriología general , que comprende los procesos comunes a todo embrión durante las ocho primeras semanas del desarrollo (período embrionario propiamente dicho), y embriología especial u…
