Study Notes
Human Development Stages
- Organogenesis occurs during the embryonic period, specifically between the third and eighth weeks after fertilization.
Sex Cell Development
- The process of gametogenesis is responsible for creating highly specialized sex cells: sperm in males and oocytes in females.
Formation of Primordial Germ Cells
- Primordial germ cells are formed in the epiblast layer of the developing embryo, specifically within the yolk sac region.
Arrival of Gametes
- Gametes derived from primordial germ cells arrive in the developing gonad (testes or ovaries) by the end of the sixth week of human development.
Cell Division During Migration
- Mitosis is the type of cell division that increases the number of primordial germ cells during their migration from the yolk sac to the developing gonads.
