OVULAR MEMBRANE Meaning and
Definition
-
The term "ovular membrane" refers to a thin and delicate structure that encloses or surrounds an egg or ovum. It serves as a protective barrier, shielding the developing embryo inside the egg from external influences and providing a suitable environment for growth and development.
The ovular membrane is typically composed of proteins and lipids, and its composition can vary across different species. In some animals, such as birds and reptiles, the ovular membrane is commonly known as the "eggshell" and is composed primarily of calcium carbonate, providing rigidity and protecting the developing embryo from desiccation, physical damage, and microbial invasion.
In mammals, the ovular membrane, also called the "zona pellucida," is a glycoprotein-rich layer that surrounds the ovum. It functions as a protective barrier and plays a crucial role in fertilization. The sperms must penetrate the ovular membrane for successful fertilization to occur.
Understanding the structure and properties of the ovular membrane is important in reproductive biology and assisted reproduction techniques. In vitro fertilization (IVF) procedures involve manipulating the ovular membrane to facilitate sperm entry and increase chances of successful fertilization.
In summary, the ovular membrane is a thin, protective covering that surrounds the ovum or developing embryo. It plays a vital role in maintaining the integrity and development of the embryo and is crucial in the process of fertilization in animals.

Etymology of OVULAR MEMBRANE
The word "ovular" is derived from the Latin word "ovulum", meaning small egg. It is a diminutive form of "ovum", which means egg. "Membrane", on the other hand, comes from the Latin word "membrana", referring to a thin layer of tissue or covering. Thus, when combined, "ovular membrane" literally means a thin layer or tissue related to or pertaining to eggs.
