EARLY DEVELOPMENT
OUTLINE
SOME TERMS
Gamete: egg or spermGametogenesis: production of eggs or spermOogenesis: production of eggsSpermatogenesis: production of spermSpermiogenesis: differentiation of sperm morphologyFollicle: where eggs mature in the ovaryOvulation: release of egg from folliclePolar body: nonfunctional product of meiotic
divisions in oogenesisZygote: Fertilized egg
SOME MORE TERMSOogonia: mitotically dividing cells in the ovary, will becomeOocytes
Primary oocyte: decision has been made to undergo meiosis, cell has grown. Cells are arrested at this stageuntil puberty.
Secondary oocyte: has completed first meiotic divisionthe division was unequal in terms of cytoplasm
Ovum: Ovulated egg, ready to be fertilized. If fertilized,the second meitoic division will occur, another polar bodywill be given off.
