Cortical reaction which results in slow block to polyspermy -cortical granules fuse with the plasma membrane and release their contents (enzymes and polysaccharides) into the space between the plasma and vitelline membranes, causing the plasma and vitelline membranes to separate from one another -water follows osmolarity gradient created by saccharides released into intermembrane space, and the vitelline membrane then swells and moves away from plasma membrane.
