CORNEAL EPITHELIUM Meaning and
Definition
-
Corneal Epithelium is the outermost layer of cells that cover the cornea, which is the transparent front part of the eye. It forms a protective barrier for the underlying corneal layers, playing a crucial role in maintaining the cornea's clarity and overall health.
The corneal epithelium is a stratified squamous epithelium, meaning it consists of multiple layers of cells that are flat and scale-like in shape. It covers the entire anterior surface of the cornea, extending from the limbus (the border between the cornea and sclera) to the central cornea. Its structure allows for efficient absorption of oxygen and nutrients from the tear film, which nourish the cornea.
This layer of the eye serves several important functions. Firstly, it acts as a mechanical barrier, protecting the cornea from physical damage and foreign particles. It also helps maintain the smoothness and regular curvature of the cornea, improving the eye's ability to focus incoming light. Additionally, the corneal epithelium aids in the defense mechanism of the eye, protecting against infections by sealing any potential entry points for pathogens.
The regenerative capacity of the corneal epithelium is high, allowing it to rapidly heal minor injuries or abrasions. However, more severe damage may require medical intervention to support the healing process.

Etymology of CORNEAL EPITHELIUM
The word "corneal" is derived from the Late Latin word "cornea", meaning "horny" or "like a horn". This term refers to the cornea, which is the transparent front part of the eye. The word "epithelium" comes from the Greek roots "epi", meaning "on" or "upon", and "thelē", meaning "nipple" or "surface". In anatomy, epithelium refers to the tissue that covers the surfaces of organs, including the cornea. So, the term "corneal epithelium" describes the outermost layer of cells that make up the surface of the cornea.
