Oct 30, 2023 · The stomach can perform these roles due to the layers of the stomach wall. These glands are lined entirely by surface mucous cells that lubricate the incoming food and protect the lining of the stomach near the gastro-esophageal junction. There are fewer parietal cells, and most of the cells are mucosa secreting cells, which you can tell from the pale staining appearance. Structure of the mucosa (gastric pits and gastric glands) in the stomach (scanning electron microscopy). "Gastric" or "fundic" glands are characteristic of the mucosa throughout the fundus and corpus regions of the stomach.

The inner surface is covered by surface mucous cells. 9, 1. gastric glands occupy gastric mucosa. Fundic Mucosa: Gastric Pits - surface invaginations lined with surface mucous cells. While the glands of the cardia mainly secrete mucins, the glands in the body and fundus contain various exocrine cells. Stomach, Biopsy: - Antral-type gastric mucosa within normal limits. Gastric Pits - surface invaginations lined with surface mucous cells. The epithelium of the mucosal layer forms gastric glands that produce acid and enzymes that help digest food. Jan 24, 2024 · The gastric mucosa is lined with single-layered, mucus-forming columnar epithelium (foveolar epithelium) that forms a protective barrier against acidic gastric juice. The submucosa is composed of loose connective tissue with some blood vessels. Pyloric Stomach. It is formed by a layer of surface epithelium and an underlying lamina propria and muscularis mucosae. The pits are deeper, and the glands shorter and more branched. Jan 16, 2023 · The stomach mucosa consists of simple columnar epithelium with deep gastric pits that connect to the glands of the stomach lining. e. The gastric wall consists of four layers: mucosa, submucosa, muscularis propria, and serosa (Fig. The mucosal (pyloric glands) in this region look different to the gastric glands in the body of the stomach. The pylorus is the narrow region that connects the stomach to the duodenum. The gastric mucosa has two main epithelial components: the superficial foveolar component and the deeper glandular component (Figs. 11).

The pyloric stomach forms the distal region of the stomach that opens into the small intestine. The cardia is the transitional region between the esophagus and body of the stomach. Gastric juice is secreted by gastric mucosal glands, and contains hydrochloric acid, mucu s, and proteolytic enzymes pepsin (which breaks down proteins), and lipase (which breaks down fats). These cells produce a thick layer of mucus (light blue) that protects the epithelium from the acid and proteolytic enzymes in the stomach.

Histologically, most of the stomach wall contains gastric glands (or fundic glands). The mucosa is composed of two epithelial components: gastric pits (the foveolae) and deeper glands (cardiac, fundic and pyloric glands) that contain endocrine cells. A vast number of gastric pits dot the surface of the epithelium, giving it the appearance of a well-used pincushion, and mark the entry to each gastric gland, which secretes a complex digestive fluid referred to as gastric juice. Histology of the fundic stomach - mucosa (gastric pits, fundic glands, mucous neck, parietal, and chief cells), Meissner's plexus, and Auerbach's plexus.
