How Do You Spell VITELLARY MEMBRANE?

1. The term "vitellary membrane" refers to a structure that is commonly found in eggs, especially in those of animals. It is a thin, transparent, and elastic membrane that surrounds the yolk or vitellus, which is the significant source of nutrients for the developing embryo. The vitellary membrane separates the yolk from the albumen, commonly known as egg white.

   The function of the vitellary membrane is to protect the yolk from external threats and maintain its hygienic environment. It acts as a barrier that strengthens the structure of the egg and prevents the entry of microorganisms, bacteria, and other potential contaminants, reducing the risk of infection.

   Moreover, the vitellary membrane also facilitates the exchange of gases, allowing oxygen to enter the egg while enabling the release of waste gases such as carbon dioxide. This exchange is vital for the respiration and growth of the developing embryo.

   In some animal species, the vitellary membrane is not present or is very thin, and the nutrients are distributed differently. However, in most avian and reptilian eggs, the vitellary membrane is reasonably prominent. It provides essential protection to the yolk until the time of hatching.

   Overall, the vitellary membrane plays a critical role in safeguarding and supporting the development of the embryo by consolidating the yolk and maintaining its integrity throughout the incubation period.
