Abstract

Ampullary receptor organs of African mormyrids consist of a cavity beneath the epidermis. The wall of the cavity contains embedded receptor cells and 2 types of supporting cells. A canal extends from the cavity to an opening at the surface. The lumen of the canal and the ampulla are filled with a jelly like material and dense cylinders apparently secreted by 2 types of supporting cells. Flattened cells of the canal wall are joined by occluding junctions. Synapses between receptor cells and the afferent nerve fiber are characterzed by a presynaptic dense body, but presynaptic vesicles were not observed. Denerating receptor cells are occasionally seen among normal receptor cells in the base of the organ.
