Respuesta :
In the slow block to polyspermy, sperm penetration releases an inflow of Ca2+, which in turn stimulates the cortical reaction.
What's the cortical response?
- A medium known as the cortical response, which is started after fertilization, stops polyspermy, or the union of several sperm with one egg.
- The cortical response, which in multitudinous species serves as the top element of the slow block of polyspermy, gradually forms an endless barricade to sperm entry in distinction to the rapid-fire-fire block of polyspermy, which incontinently but temporarily inhibits new sperm from fertilizing the egg.
- This hedge is made up of the egg's tube membrane and cortical grains, specialized secretory vesicles set up in the cortex( behind the tube membrane) of the egg.
What follows the cortical response?
- Cortical grains( CG), a type of specific organelle in the egg, release their contents into the perivitelline region after sperm and egg fuse( cortical response), making the zona pellucida resistant to sperm adherence and penetration.
