Paneth cell


Noun

1. Along with goblet cells, enterocytes, and enteroendocrine cells, represent the principal cell types of the epithelium of the small intestine. (A few may also be found sporadically in the cecum and appendix.) They are identified microscopically by their location just below the intestinal stem cells in the intestinal glands (AKA crypts of Lieberkühn) and the large eosinophilic refractile granules that occupy most of their cytoplasm. These granules consist of several anti-microbial compounds and other compounds that are known to be important in immunity and host-defense. (wikipedia.org)

2. Coarsely granular secretory cells found in the basal regions of crypts in the small intestine. (biology-online.org)

Word origin: Named after Joseph Paneth (1857–1890), an Austrian physician.
