Histological structure of Ilium

 Histology of Intestine

The intestine is long tube-like divisible into Small intestine and large intestine. The small intestine consists of Duodenum and Ilium, while the large intestine consists of the Colon and Rectum. 

T. S. of  Ilium of Mammal

Histologically, the ileum has the same basic structure as the jejunum:

1.     Serosa

2.  muscularis externa

3.  Sub-mucosa

4.  Muscularis mucosa

5.  Mucosa

1.     Outermost layer of the stomach is called serosa is made up of squamous epithelium.

2.     Muscularis externa consists of outer longitudinal and inner circular muscle layer.

3.     The submucosa contains is made up of connective tissue containing blood vessels, nerves,  lymph nodes, and the Meissner’s plexus.

4.      Below the submucosa there is muscularis mucosae consists of two layers of muscle . Accordingly, they are called longitudinal muscle layers and circular muscle layers.

5.     The muscularis mucosae is followed by the thickest layer called the mucosa

6.     The mucosa membrane of the ilium shows large and small finger-like folds called villi covered by simple columnar epithelium with dispersed goblet cells.

7.     Each villus shows the presence of blood vessels, lymph vessels, and lacteal.

8.     At the base between the villi Crypts of Liberkuhn are present which lead into Bruner's gland.

4. The secretion of these glands forms digestive juices.
