, Fertilization
Gametes – Oocyte, Sperm
Acrosomal reaction
Cell Fusion
Cortical reaction
Completion of Meiosis – 2nd polar body released
Pronuclear fusion
Zygote = fertilized egg
, Oocyte
Corona radiata, follicle cells
Zona pellucida, acellular – 3 primary glycoproteins (ZP1, 2, 3)
Cortical Granules – vesicles, hydrolytic enzymes, polysaccharides
Female pronucleus
From KL Moore, 1977

Acrosome
Neck (junction)
Tail (middle piece;
end piece) – mitochondria,
microtubule system
