The mucous membranes (or mucosae; singular: mucosa) are linings of mostly endodermal origin, covered in epithelium, and are involved in absorption and secretion. ...
In anatomy, the stomach (in ancient Greek στόμαχος) is an organ of the gastrointestinal tract involved in the second phase of digestion, following mastication. ...
A gland is an organ in an animals body that synthesizes a substance for release such as hormones, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland). ...
Gastric pits are indentations in the stomach which denote entrances to the glands. ...
In the fresh state it is of a pinkish tinge at the pyloric end, and of a red or reddish-brown color over the rest of its surface. In infancy it is of a brighter hue, the vascular redness being more marked. A human infant The word Infant derives from the Latin in-fans, meaning unable to speak. ...
It is thin at the cardiac extremity, but thicker toward the pylorus. During the contracted state of the organ it is thrown into numerous plaits or rugae, which, for the most part, have a longitudinal direction, and are most marked toward the pyloric end of the stomach, and along the greater curvature. These folds are entirely obliterated when the organ becomes distended. This page is about the muscular organ, the Heart. ...
Rugae are the mucus-covered ridges, or folds, located on the inside of the stomach wall. ...
The greater curvature of the stomach is directed mainly forward, and is four or five times as long as the lesser curvature. ...
When examined with a lens, the inner surface of the mucous membrane presents a peculiar honeycomb appearance from being covered with small shallow depressions or alveoli, of a polygonal or hexagonal form, which vary from 0.12 to 0.25 mm. in diameter. These are the ducts of the gastric glands, and at the bottom of each may be seen one or more minute orifices, the openings of the gland tubes. The alveoli (singular:alveolus), tiny hollow sacs which are continuous with the airways, are the sites of gas exchange with the blood. ...
The fundus glands (or fundic glands, or gastric glands) are found in the body and fundus of the stomach. ...
The surface of the mucous membrane is covered by a single layer of columnar epithelium with occasional goblet cells. This epithelium commences very abruptly at the cardiac orifice, where there is a sudden transition from the stratified epithelium of the esophagus. The epithelial lining of the gland ducts is of the same character and is continuous with the general epithelial lining of the stomach. In zootomy, epithelium is a tissue composed of a layer of cells. ...
Goblet cells are glandular epithelial cells that are specifically designed to secrete mucus. ...
The cardia is the anatomical term for the junction orifice of the stomach and the esophagus. ...
The esophagus (also spelled oesophagus/Å“sophagus), or gullet is an organ in vertebrates which consists of a muscular tube through which food passes from the mouth area to the stomach. ...
