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. ...
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.
[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 ...
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.
Aberrant crypt foci (ACF) are clusters of abnormal tube-like glands in the lining of the colon and rectum. Aberrant crypt foci form before colorectal polyps and are one of the earliest changes seen in the colon that may lead to cancer. ACF are, as opposed to normal epithelial cells, apoptosis resistant.
For example, verus is listed without the variants for Aloe vera or Galium verum. The second part of a binomial is often a person's name in the genitive case, ending -i (masculine) or -ae (feminine), such as Kaempfer's tody-tyrant, Hemitriccus kaempferi. The name may be converted into a Latinised form first, giving -ii and -iae instead.
