VITELLINE MEMBRANE Meaning and
Definition
-
The vitelline membrane is a specialized membrane that surrounds the yolk of an egg. It is a thin, transparent layer composed mainly of proteins. This membrane is present in various types of eggs, including those of birds, reptiles, and some insects.
The vitelline membrane acts as a protective barrier, preventing the yolk from being damaged or contaminated. It serves as a physical shield against external elements and microorganisms, ensuring the integrity and safety of the developing embryo.
In addition to its protective function, the vitelline membrane is also involved in important biological processes. It plays a role in nutrient absorption and metabolism, facilitating the transfer of essential substances from the yolk to the developing embryo. This membrane also aids in gas exchange, allowing oxygen to enter the egg and carbon dioxide to be expelled.
During fertilization, the vitelline membrane is essential for the fusion of the sperm and egg. It acts as a recognition site for the sperm, allowing it to bind and penetrate the membrane, ultimately leading to the fusion of genetic material and the initiation of embryonic development.
Overall, the vitelline membrane is a critical component of the egg structure, providing protection, facilitating nutrient absorption and gas exchange, and participating in the fertilization process.

Etymology of VITELLINE MEMBRANE
The word "Vitelline Membrane" is derived from Latin and Greek roots.
"Vitelline" is derived from the Latin word "vitellus", which means "yolk". The Latin word "vitellus" originated from the earlier Latin word "vitulus", meaning "a calf". This connection likely comes from the color similarity between the yolk and the calf's coat.
"Membrane" stems from the Latin word "membrana", a noun that refers to a thin, pliable layer. This term is derived from the Proto-Indo-European root *mems-, meaning "flesh" or "muscle".
Therefore, the etymology of "Vitelline Membrane" involves the Latin word for yolk and the Latin term for a thin layer.
