<span>Blockage of the Cerebral Artery can reduce blood supply to the brain, causing a stroke (Ishcemic Stroke)
Blood is carried to the brain by two pair of arteries, i) The Internal Carotid arteries, ii) The Vertebral arteries.

Explanation:
The formation of fertilization envelope is well-studied on the model system- sea urchin. It has been shown that, the fertilization envelope is formed after the initial sperm-egg interaction from the egg surface vitelline envelope and the paracrystalline protein fraction which is derived from cortical granules. Secretion from cortical granules, prevents polyspermy.
