primitive, ciliated excretory cell in trematodes; the movement of the cilia on this cell within the miracidium larva within a schistosome egg indicates egg viability.
A hollow cell in the excretory system of certain invertebrates, including flatworms and rotifers, containing a tuft of rapidly beating cilia that serve to propel waste products into excretory tubules.
flame cell(flām sel)
Primitive, ciliated excretory cell in trematodes; the movement of the cilia on this cell within the miracidium larva within a schistosome egg indicates egg viability.
flame cella specialized cell that contains a central cavity with several beating cilia. These create a current in the tubules to which they are connected. The tubules usually open to the exterior and flame cells control the water content of the body. The flame cell and tubule is known as a protonephridium and is found in PLATYHELMINTHS, NEMERTINES, rotifers, ANNELIDS, the larvae of molluscs and AMPHIOXUS.
1. the luminous, irregular appearance usually accompanying combustion, or an appearance resembling it.
2. to render sterile by exposure to a flame.
the excretory cell in cestodes and trematodes; their number and arrangement is a basis for identification.
in skin lesions such as insect bite reactions, eosinophilic granulomas; characterized by areas of altered collagen surrounded by eosinophils and eosinophilic cytoplasmic granules.
inactive hair follicles with excessive trichilemmal keratinization.
