Gametogenesis Flashcards
Gametogenesis
creation of gametes
Fertilization
union of sperm and egg cell
Chemoattractant
by egg cell to sperm
Facilitated Fertilization
nanotechnology injects sperm
In Vitro Fertilization
collect egg and sperm, when fertilized, injected to uterus
Sperm Cell Head
part that enters, contain nucleus and acrosome (digs up egg cell)
Sperm Cell Middle
contains mitochondrion
Spermatogenesis
during puberty when hypothalamus is triggered and happens in testes
Triggered Testosterone
produces sperm cell
Inhibin
limiter of sperm production
Seminal Fluid
protects the sperm
Process of Spermatogenesis
primordial germ cell - mitosis - spermatogonium - itself and sperm - primary spermatocyte - meiosis 1 - secondary spermatocyte - meiosis 2 - sperm
1 Spermatogonium
4 sperm cells
1 Primary Spermatocyte
2 secondary spermatocytes
Ovum
layers thicken when sperm enters to prevent polyspermy
