Columnar Section

Simple columnar epithelia line the uterus.
Columnar section. Squamous columnar and cuboidal. Each rock unit is distinguished by an appropriate lithologic symbol and the thicknesses of the units are drawn to scale. A simple columnar epithelium is a single layer of columnar cells attached to the basement membrane with oval shaped nuclei located in the basal region.
In other words a column is a compression member. There are three principal shapes of epithelial cell. A columnor pillarin architectureand structural engineeringis a structural element that transmits through compression the weight of the structure above to other structural elements below.
Columnar section a simplified graphic representation of the succession of rocks in a particular area shown in the form of a column with the oldest rocks at the bottom. In humans a simple columnar epithelium lines most organs of the digestive tract including the stomach small intestine and large intestine. A vertical strip or scale drawing of the strip taken from a given area or locality showing the sequence of the rock units and their stratigraphic relationship and indicating the thickness lithology age classification and fossil content of the rock units.
