Stomach This slide shows the structure of the stomach lining under the light microscope. If you look closely, you can see the numerous glands invaginating into the lamina propria.

The jejunum is about 0.9 meters (3 feet) long (in life) and runs from the duodenum to the ileum. Begin by identifying the folds of the stomach wall, or rugae, which are visible in a gross specimen. For example: (Stain - Haematoxylin Eosin) Histology Glossary - Specialised glossary for histology terms and micro-anatomy. Stomach. Look at slide 162 first. Small Intestine. Duodenum. Mucosa (or mucous membrane) Villi - tall, slender finger-like projections that extend into the lumen. To improve the efficiency of absorption, it is necessary to increase surface area.

Absorptive Cells (or Enterocytes) - simple columnar cells with microvilli (or brush border) to expand the absorptive surface. It examines the correlation between structure and function. The jejunum is a continuation of the small intestine following the duodenum.It begins at the duodenojejunal flexure, where the small intestine turns sharply toward the anterior direction.

It is roughly horseshoe-shaped, with the open end up and to the left, and it lies behind the liver.On anatomic and functional grounds, the duodenum … Figure 1. By Shizra Nizamani 2. Histology of small intestine 1. It is responsible for the absorption and digestion of nutrients. from the pancreas and gall bladder. Duodenum. Liquefied food (chyme) exits the stomach and enters the first portion of the small intestine, known as the duodenum. The three regions of the small intestine are the duodenum, jejunum, and ileum. The digestive process is facilitated by the enzymes produced by the pancreas. Rather than reproducing the information found in a histology textbook, a user is shown how to apply this knowledge to interpret cells and tissues as viewed through a microscope. Slide List. Also Brunner glands in duodenum Brunner glands: Submucosal mucous glands in duodenum, secrete bicarbonate ions, glycoproteins, pepsinogen II Resemble gastric pylorus mucous glands Muscularis propria (externa): Inner circular and outer longitudinal layer, with myenteric (Auerbach) plexus between these layers intestine, known as the duodenum. It plays an important role for digestion as 40% of the whole small intestine is jejunum. The duodenum is the shortest segment of the intestine and is about 23 to 28 cm (9 to 11 inches) long. The duodenum is composed of the four layers characteristic of the gastrointestinal tract.
