Histologically, what feature is shared by all tonsils but is absent in other malt nodules?
ira [324]

Crypts Feature is shared by all tonsils but is absent in other malt nodules. Anatomical structures called crypts are deep, narrow incisions into larger structures. The Crypts of Lieberkühn are a typical type of anatomical crypt.

It is not the only form of the tonsil, though; some tonsils also feature crypts. The deep regions of these tonsils are accessible to the outside world through these crypts, making them more susceptible to infection. An intestinal gland, also known as a Lieberkühn crypt or intestinal crypt, is a gland that can be found in the small and large intestines' intestinal epithelium between villi (or colon).

The epithelium that covers the glans and intestinal villi are made up of a variety of cells, including enterocytes (which absorb water and electrolytes), goblet cells (which secrete mucus), enteroendocrine cells (which secrete hormones), cup cells, tuft cells, and Paneth cells (which secrete antimicrobial peptides) and stem cells at the base of the gland.
