Yes, its unencapsulated, found in lamina propria and submucosa of small intestine. It has M cells that take up antigen.

Peyer's patches , known as aggregated lymphatic follicles. They are similar to the tonsils and are found throughout the body, especially in the mucous linings of the digestive and respiratory tracts.

As for their location in their GI tract, Peyer's patches are found in the ileum and the colon.

I agree with Sakaki. I'd say Ileum, too. Don't know about colon.

How about Brunner's glands? They are found in the submucosa of the duodenum, right? Last part of duodenum????

Yes you are rite bela, brunners glands secrete alkaline mucus, and are located in submucoase of duodenum. Duodenal ulcers cause hypertrophy of these glands smiling face

Brunner's glands are located throughout the entire duodenum, and we can use them as a histologic feature to identify the duodenum (not just the "last part of the duodenum").

Thnx sakaki for the clarification smiling face

And hey, I looked up peyer's patches in FA and they're saying Small Intestine only (ILEUM as I recall from a test q). So, I don't think u see them in the colon. :?

Yeah, you're right, rida and Bela. My mistake; they're just called lymphoid follicles in the colon. :/

Watch out! Lymphoid follicles have not the same organization than Peyer's patches. Peyer patches are bigger, made by several lymphoid follicles.
