Colonic crypts (intestinal glands) within four tissue sections. In panel A, the bar shows 100 μm and allows an estimate of the frequency of crypts in the colonic epithelium. Panel B includes three crypts in cross-section, each with one segment deficient for CCOI expression and at least one crypt, on the right side, undergoing fission into two ...
Crypts are anatomical structures that are narrow but deep invaginations into a larger structure. One common type of anatomical crypt is the Crypts of Lieberkühn. [1] However, it is not the only type: some types of tonsils also have crypts. Because these crypts allow external access to the deep portions of the tonsils, these tonsils are more ...
The Crypts of Lieberkühn (intestinal glands) are named for him; he first described these in detail in De fabrica et actione vollorum intestinorum tenuium hominis, in 1745. Beyond this, Lieberkühn produced optical instruments such as compass microscopes with Lieberkühn reflector , further developing the light microscope , which he had seen ...
Acquired via fecal contamination of food and water (oral-fecal route), it undergoes endogenous merogony in the crypts of Lieberkuhn (intestinal ceca of chicken) and gametogony in epithelial cells of the small intestines. Fusion of microgamete and macrogamete forms results in unsporulated zygotes, which are released with feces of chicken. The ...
