STRATIFIED SQUAMOUS EPITHELIUM – 2
At first glance, it may not be easy or obvious to see that the shape of the cells varies according to their distance from the basal layer.
Note the following details in the image:
The basal layer is in the lowest position of the epithelial layer, supported by connective tissue. The nuclei of the cells of the basal layer are very close to each other, meaning that the cells have little cytoplasm.
A little higher up, the nuclei are further apart from each other. The cells increased their size. Their shape still appears to be polyhedral.
From a certain level of the epithelial sheet, elongated nuclei can be seen (yellow arrows after moving the mouse or clicking). This means that the cells have become flattened, pavement-like.
On the surface of the epithelium, the nuclei are more heavily stained and quite flattened (green arrows). The cells ate the surface are very thin, resembling tiles or scales. These cells that undergo desquamation.
