Q

Shape of Cells:

SQUAMOUS CELLS
(SKWAY-muss; squam- = “scales”)

[classification based on the shape of cells in those layers]

A

Epithelial cells that are flat and scale-like in appearance and are constantly shed and replaced by new cells. They protect the skin from evaporation and from outside forces that could puncture the skin and, thus, cause bleeding.

They are found in the top layer of the skin, called the epidermis.They are also found in the mouth, throat, esophagus, lungs, cervix, anus, and bladder.
