What Is the Average Size of a Cheek Cell?

The average size of a human cheek cell is 60 micrometers in diameter. The average size of a human cheek cell nucleus is about 5 micrometers (microns) in diameter.

Squamous epithelial cells, or cheek cells, lack plant structures, such as a cellulose cell wall. Because of this, these cells are not rigid and have irregular shapes. The main functions of epithelial cells include protection and secretion. In the case of cheek cells, they continuously supply mucin, which is the main component of mucous. Cheek cells reproduce rapidly. This induces quick healing when food or other external objects cause tears to the inside of the mouth.
