Peyer’s Patches: These are lymphoid follicles similar in many ways to lymph nodes, located in the mucosa and extending into the submucosa of the small intestine, especially the ileum.
Are Peyer’s patches found in submucosa?
Microscopically, Peyer’s patches appear as oval or round lymphoid follicles (similar to lymph nodes) located in the mucosa layer of the ileum and extend into the submucosa layer.
Where is Peyer’s patch located?
the small intestine
Peyer’s patches (about 8–10) and SF are found in the walls of the small intestine or both small and large intestine, respectively.
Where Peyer’s patches are present?
Peyer patches are round or oval and are located in the mucous membrane lining of the intestine. They can be seen by the naked eye as elongated thickened areas, and their surface is free of the projections (villi) and depressions (Lieberkühn glands) that characterize the intestinal wall.
