title: Ultrastructure of the paralimbal and juxtacaruncular human conjunctiva.
abstract: The epithelial fine structure of the juxtacaruncular and the medial paralimbal human conjunctiva was evaluated. In both locations the following types of cells could be identified: (1) basal cells containing numerous intermediary filaments (dark basal cells); (2) basal cells containing many mitochondria (light basal cells); (3) wing cells (spinocytes containing numerous filaments that were fewer and formed smaller bundles than those of the dark basal cells; (4) flattened, dark superficial cells; (5) wing-cell-like superficial cells. In addition, the juxtacaruncular conjunctiva contained the following cell types: goblet cells, light wing cells containing a multitude of polysomes, light wing cells containing dilated profiles of rough endoplasmic reticulum (rare), and light wing cells containing numerous microtubules (rare).
