B0002392 Surface of the corneal epithelium – coloured
Credit: Rob Young. Wellcome Images
Transmission electron micrograph showing surface
epithelial cells in a human cornea. A dead surface
cell is about to slough away. Below the dead
layer is the squamous layer, then the wing cells
and towards the lower right are the columnar
epithelial cells. A small lymphocyte is present in
the wing cell layer and can be distinguished
by its small size and large nucleus. Desmosomes
appear as dark areas on the cell membranes and
function to attach cells to each other and
maintain the integrity of the epithelial sheet.
