It is essential for maintaining moisture in the eye and protecting against foreign particles.

Palpebral conjunctiva refers to the delicate mucous membrane that covers the inner surface of the eyelids, in close proximity to the eyeball. More specifically, it is the thin, transparent tissue that lines the inside of the upper and lower eyelids, forming a protective barrier between the eyelid and the eyeball.
The palpebral conjunctiva is composed of non-keratinized stratified squamous epithelium, which is a type of tissue that does not contain a hard outer layer of cells. This epithelium is supported by a layer of connective tissue, and it contains numerous fine blood vessels that help in nourishing the conjunctiva. The conjunctiva in this area is also equipped with tiny hair-like structures called cilia that assist in keeping the eye lubricated by spreading tears over the eyeball and draining them into the puncta, openings on the eyelid margin.
The palpebral conjunctiva plays an essential role in maintaining the health and functionality of the eye. It protects the delicate structures of the eye from dust, debris, and microbial infections. Additionally, the transparency of the conjunctiva allows for the transmission of light to the cornea, which is necessary for vision.
In summary, the palpebral conjunctiva is the thin, transparent mucous membrane that lines the inner surface of the eyelids, providing protection, lubrication, and a vital support system for the eye.
The word "palpebra conjunctiva" is derived from Latin and Greek roots.
