Question

question 7 flag question
where do m (microfold) cells occur?
answers: a - e
a lymph node
b duodenum
c spleen
d ileum
e jejunum

Explanation:

M cells (Microfold cells) are specialized epithelial cells found in the follicle - associated epithelium (FAE) overlying Peyer's patches. Peyer's patches are lymphoid aggregates located in the ileum (the last part of the small intestine). The other options:

• Lymph nodes are secondary lymphoid organs but not the site of M - cell location.
• The duodenum and jejunum do not have the characteristic Peyer's patches with M cells in the same abundance as the ileum.
• The spleen is a different lymphoid organ and not the site for M - cell occurrence.

Answer:

D. ileum
