Osphradium
osphradium[äs′frād·ē·əm] (invertebrate zoology) asphradium Osphradium a receptor organ of mollusks, formed of specialized sensory epithelium. The osphradium is located in the mantle cavity, usually where the water passes to the branchial organs. It is well developed in some gastropod mollusks, in which it apparently serves as an olfactory organ. The functions of osmoreception and mechanoreception are also attributed to the osphradium. |
