Hello, this is my first time posting in the forums, and I wanted to know if there were some posters here who could help me with an anatomy concept that's driving me nuts. In my anatomy/physiology class, we are currently learning the different types of layers. I understand the classification of layers, how to name them, etc. What is blowing my mind is the following: If simple epithelium is made up of only ONE layer of cells, how in the world could it make up the structures in the body which are, by logic, made up of thousands of cells? Even stratified epithelium that I find pictures of on google and such show that the difference between the apicl surface and the basement membrane is between 5 to 10 layers of cells. Last time I checked, the stomach lining was not 10 cells thick. I'm sure I'm missing something here, but I can't figure out what. I think it has to do with my difficulty of picturing tissues as 3-Dimensional with 2-D pictures. My view of how I THINK the stomach is structured is in the attached file. It is a sectional view of the stomach lining. Please, let me know if the way I picture it is correct, or if not, how it is actually structured. I have an exam on monday, and although I don't need to know this for it, it would help me understand the concept of tissues greatly.
