Image of the mucosa of the stomach, showing an epithelium (at top, and also facing the elongated cavities) made up of column-shaped cells. The epithelial lining of the mucosa, differs along the gastrointestinal tract. [1] The epithelium is described as stratified if it consists of multiple layers of cells, and simple if it is made up of one ...
Simple columnar epithelium is a single layer of columnar epithelial cells which are tall and slender with oval-shaped nuclei located in the basal region, attached to the basement membrane. In humans, simple columnar epithelium lines most organs of the digestive tract including the stomach , and intestines .
Foveolar cells in the antrum of stomach. A skewed cross-section of the columns gives a false impression of being stratified epithelium. Foveolar cells line the surface of the stomach and the gastric pits. They constitute a simple columnar epithelium, as they form a single layer of cells and are taller than their width. Other mucus-secreting ...
By layer, epithelium is classed as either simple epithelium, only one cell thick (unilayered), or stratified epithelium having two or more cells in thickness, or multi-layered – as stratified squamous epithelium, stratified cuboidal epithelium, and stratified columnar epithelium, [8]: 94, 97 and both types of layering can be made up of any of ...
Parietal cells (also known as oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach. [ 1 ]
vaginal epithelium: Stratified squamous, non-keratinized - reproductive - female: labia majora: Stratified squamous, keratinized - reproductive - male: tubuli recti: Simple cuboidal: germinal epithelium (male) reproductive - male: rete testis: Simple cuboidal - reproductive - male: efferent ducts: Pseudostratified columnar - reproductive - male ...
Gastric pits are indentations in the stomach which denote entrances to 3-5 tubular gastric glands. [1] [2] They are deeper in the pylorus than they are in the other parts of the stomach. The human stomach has several million of these pits which dot the surface of the lining epithelium.
A compact epithelial cell lining. Cells in the epithelium of the stomach are bound by tight junctions that repel harsh fluids that may injure the stomach lining. A special mucus covering, derived from mucus secreted by surface epithelial cells and Foveolar cells. This insoluble mucus forms a protective gel-like coating over the entire surface ...
