Stratum basale (stratum geminativum)
Simple epithelium occurs in a single layer. It is composed of a single layer of cells that are tightly packed together, forming a thin barrier. It plays important roles in absorption, secretion, and protection in various tissues and organs of the body.
A simple columnar epithelium is a single layer of elongated cells.
a simple epithelium
simple squamous
This is referred to as the simple squamous epithelium. These cells contact the basement membrane and they are flat and thin.
they are flat cells. they can either be simple (one layer) or stratified (multiple layers)
A simple columnar epithelium is a single layer of elongated cells.
If epithelial cells are more than one layer thick, it is considered stratified epithelial tissue.
Cheek cells
a simple epithelium
Simple = One layer Columnar = tall (column like) cells Epithelium = Lining, covering, and glandular tissue Simple columnar epithelium = A single layer of tall cell tissue
simple squamous
Single layer of Simple Squamous Epithelium
To be defined as stratified an epithelium must contain 2 or more layers of cells. There is not upper limit on how many layers it could contain but there must be at least two. The exact number of layers in any given epithelium is variable as statified epithelium is usually present in areas of wear and tear and so some layers are always being scraped of and other grown.
The epithelial layer of the serous membrane is known as the mesothelium and consists of a single layer of simple squamous epithelium which produce the serous fluid. These cells are bound tightly to the second and underlying connective tissue.
This is referred to as the simple squamous epithelium. These cells contact the basement membrane and they are flat and thin.
The term for epithelium with more than one layer is stratified epithelium.
