Stomach This region of the stomach is called the 'cardiac' region. How does the mucosa in this region change? Gastric Glands in the fundus (body) of the stomach. The epithelium of the mucosa of the fundus and body of the stomach forms invaginations called gastric pits. The lamina propria contains gastric glands, which open into the bases of the gastric pits. These glands are responsible for the synthesis and secretion of the gastric juice.

What are the Characteristics of Epithelial Tissue? The most basic characteristic of epithelial tissue is that it covers the surfaces of the body, whether external or internal. It acts as a protective covering or boundary for such surfaces, including the outer layer of the skin, as well as the inner surface of hollow organs like the stomach, colon, and blood vessels.espiratory epithelium separated by bands of inflamed tissue and muscle. Skin is epithelial tissue more than one cell thick and known as stratified epithelium. Epithelial cells lining the digestive tract -- including those of the esophagus, stomach and intestines -- undergo continuous division.

Epithelial Tissue: lining and covering The epithelium is a layer of cells-epithelial cells. They are highly specialised for selective secretion and absorption of ions and molecules. Epithelial cells line any surface that comes into contact with the external environment. So-the airways, the gut, the urinary tract, the cornea etc.Together with an underlying layer of connective tissue, they form mucous membranes. Epithelium may also line the surface of internal organs. An epithelial cells is said to be polarised as either side of the cell differs in terms of structure and function.hey are highly specialised for selective secretion and absorption of ions and molecules. Epithelial cells line any surface that comes into contact with the external environment. So-the airways, the gut, the urinary tract, the cornea etc.

Epithelial Tissue Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers. Simple cuboidal epithelium is found in glandular tissue and in the kidney tubules. Simple columnar epithelium lines the stomach and intestines.pithelial Tissue. Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

What type of tissue is the stomach made of? Answers. Best Answer: rugae or folds give the stomach its well-known ability to enlarge when engorged with food. the outermost layer of these folds is mucus which helps protect the tissues below from the harsh environment of the stomach. The innermost layer is a lining of simple columnar epithelium.This type of epithelium provides the greatest surface area for absorption or secretion. In the stomach the epithelial cells exposed to the lumen are primarily constructed to resist digestion by the lumen contents.nswers.

Gastric mucosa Source: CRISP. Gastric mucosa: Surface epithelium in the stomach that invaginates into the lamina propria, forming gastric pits. Tubular glands, characteristic of each region of the stomach (cardiac, gastric, and pyloric), empty into the gastric pits. The gastric mucosa is made up of several different kinds of cells.

- Beneath the gastric pits, the mucosa of the stomach is filled with closely packed tubular glands, which differ by region (i.e., cardiac, fundic, pyloric). Histologically, most of the stomach wall contains gastric glands (or fundic glands).These consist primarily of parietal cells and chief cells.mages. The surface is indented into numerous short gastric pits which open freely to the lumen. The entire surface consists uniformly of surface mucous cells, which protect the stomach from self-digestion. Failure of the surface mucous cells to protect the stomach wall can lead to an ulcer.

Epithelium Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue. The other three types are connective tissue, muscle tissue and nervous tissue.he lining of the esophagus is an example of a non-keratinized or moist stratified epithelium. Transitional. Transitional epithelia are found in tissues that stretch and it can appear to be stratified cuboidal when the tissue is not stretched or stratified squamous when the organ is distended and the tissue stretches.

Stomach The lining epithelium of the stomach, and gastric pits is entirely made up of mucous columnar cells. These cells produce a thick coating of mucus, that protects the gastric mucosa from acid and enzymes in the lumen. Even so, these cells have to be replaced after 4-6 days.hen the stomach is empty, and not distended, the lining is thrown up into folds called rugae. After eating, these folds flatten, and the stomach is able to distend greatly. The stomach has three anatomical regions: 1  cardiac, which contains mucous secreting glands (called cardiac glands) and is closest to the oesophagus.

Layers of the Stomach 1. Mucosa. This is the innermost layer of the stomach. The main job of the mucosa is to secrete mucus that protects the stomach from its own acids. In this layer, small pores known as gastric pits are responsible for creating the acids that the mucosa protects the stomach from.

- In the oral cavity and esophagus, stratified squamous epithelia occur as a mucous or non-keratinized type, designed for protection and lubrication during chewing and swallowing. This mucous variety also occurs in the rectum and lower portions of the female reproductive tract.n contrast to the keratinized stratified squamous epithelium, flattened surface cells of a mucous type are nucleated and living. Non-keratinized or mucous type, stratified squamous is found in: the oral cavity. esophagus to the stomach junction. anus and rectum.

What is Stomach Tissue? Epithelial tissue also protects the organs. This tissue is not only in the stomach, but it can also be found surrounding the body's organs, in the outer layer of the skin, and on the inside of the mouth.ust outside the epithelial tissue is the lamina propria. This is a thin layer of loose connective tissue that contains a moist lining of mucous membranes. Together with the epithelial tissue, it makes up the mucosa, which secretes gastric acid to aid in digestion. It also absorbs nutrients from the stomach.

Stomach - Part 2 : The inner-layers of the Stomach In order to identify the different types of cells that line the stomach and the functions of each of these types of cells it is necessary to describe the inner-layers of the stomach (i.e. the layers of the mucosa).1). Above: Diagram of the Stomach Wall. The epithelial cells that line the stomach form the mucosal epithelium layer. When the stomach is empty the mucosa lies in large folds called rugae and which look like wrinkles.

General Structure of the Digestive System The mucosa, or mucous membrane layer, is the innermost tunic of the wall. It lines the lumen of the digestive tract. The mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.In certain regions, the mucosa develops folds that increase the surface area. Certain cells in the mucosa secrete mucus, digestive enzymes, and hormones.he mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.

Precancerous conditions of the stomach Gastric epithelial dysplasia. Gastric epithelial dysplasia occurs when the cells of the stomach lining (mucosa) become abnormal. These abnormal cells may eventually progress to adenocarcinoma, the most common type of stomach cancer.Gastric epithelial dysplasia can be divided into 2 types: 1  low-grade dysplasia.astric adenoma. Gastric adenoma (adenomatous gastric polyp) is a type of polyp made up of abnormal (atypical) glandular cells from the stomach lining. They are found in areas of the stomach where the normal tissue has been changed by chronic inflammation.
