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 ...
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 ...
Cryptids are animals or other beings that cryptozoologists believe may exist somewhere in the wild, but whose present existence is disputed or unsubstantiated by science. ...
[citation needed] The largest and deepest of the crypts is the crypta magna located near to the upper pole near the soft palate. [2] The crypto magna represents the remains of the second pharyngeal pouch. [2] Macrophages and other white blood cells concentrate by the tonsillar crypts as well, in response to the microorganisms attracted to the ...
The gastrointestinal tract is composed of numerous cell types that are important for immune activation and barrier surface defenses. The gastrointestinal epithelium is composed of enterocytes, goblet cells, Paneth cells, enteroendocrine cells, tuft cells, and stem cells.
Placing a corpse into a crypt can be called immurement, and is a method of final disposition, as an alternative to, for example, cremation. Crypts are usually found in cemeteries and under public religious buildings, such as churches or cathedrals , but are also occasionally found beneath mausolea or chapels on personal estates.
Stomatal crypts can be an adaption to drought and dry climate conditions when the stomatal crypts are very pronounced. However, dry climates are not the only places where they can be found. The following plants are examples of species with stomatal crypts or antechambers: Nerium oleander , conifers, Hakea [ 26 ] and Drimys winteri which is a ...
In developmental biology, invagination of epithelial sheets occurs in many contexts during embryonic development. Invagination is critical for making the primitive gut during gastrulation in many organisms, forming the neural tube in vertebrates , and in the morphogenesis of countless organs and sensory structures.
