1 Structure and function of the conjunctiva The conjunctiva covers the exposed part of the scleraopaque part of eye)and the inner surface of the eyelids The epithelial tissue is stratified and contains goblet cells in the surface layers Goblet cells synthesize and secrete mucus that contributes to the protective and lubricating layer on the exposed surface of the eye Underneath the epithelial tissue is the conjunctival stroma, a loose vascular supportive tissue1.
