What is the membrane that lines the inside of the eye?
a transparent membrane covering the eyeball and under surface of the eyelid Mucous membrane that lines the eyelid and covers the white portion of the eye. A thin mucous membrane, helps keep the outside of the eye moist, lines the inner surface of the eyelids and folds back over the white of the eye CILIARY BODY
What are the two types of transparent tissue in the eye?
In the anterior portion of the eye there are two types of tissue that are transparent; the bulbar conjunctiva, and the cornea. The conjunctiva covers the visible part of the globe (eye ball), except for the corneal area that is in front of the iris.
What is the function of the mucous membrane of the eye?
Mucous membrane that lines the eyelid and covers the white portion of the eye. A thin mucous membrane, helps keep the outside of the eye moist, lines the inner surface of the eyelids and folds back over the white of the eye
What is the function of the middle layer of the eye?
The opaque middle layer of the eyeball a thin highly vascular layer between the sclera and the retina. It supplies blood to the retina and conducts arteries and nerves to other structures in the eye.
What is a thin transparent surface of the eyelids and an anterior surface of the eye?
Conjunctiva. The conjunctiva is a transparent mucous membrane that lines the inner surface of the eyelids (palpebral conjunctiva) and the anterior surface of the sclera (bulbar conjunctiva).

Why is cornea transparent?
The corneas of all animal species remain transparent because of the epithelial barrier, the stromal latticelike arrangement of the collagen fibrils, and the endothelial cells. Depending on the species, the corneal epithelium, the corneal endothelium, or both have a major role in regulating corneal hydration.
Is the retina transparent or opaque?
The retina, with the exception of the blood vessels coursing through it, is transparent to the examiner up to its outer layer, the retinal pigment epithelium. The transparent portion of the retina is known as the neurosensory retina.
