fertilization membrane (n)
the membrane that forms around a fertilized ovum and prevents penetration by additional spermatozoon
fertilization membrane Sentence Examples
- Fertilization membrane, also known as the egg's protective coat, is a thin layer that forms around the egg of an animal after fertilization.
- The fertilization membrane is formed as a result of the cortical reaction, a series of biochemical events that occur in the egg's cortex, the outer layer of the egg.
- The cortical reaction triggers the release of calcium ions from the endoplasmic reticulum, which leads to the activation of enzymes that modify the egg's extracellular matrix.
- The modified extracellular matrix forms a tough and impenetrable barrier that prevents the entry of additional sperm cells, a process known as polyspermy.
- After fertilization, the fertilization membrane serves to protect the developing embryo from mechanical stress and infection.
- The fertilization membrane also helps in the formation of the perivitelline space, a fluid-filled cavity that surrounds the embryo.
- The perivitelline space provides a suitable environment for embryonic development and enables the exchange of nutrients and waste products.
- The fertilization membrane is gradually degraded by enzymes produced by the embryo, and it eventually disappears as the embryo grows and develops.
- The process of fertilization membrane formation and its subsequent degradation are essential for the successful development of the embryo.
- Alterations in the formation or degradation of the fertilization membrane can lead to embryonic abnormalities and developmental defects.
