Structural and functional features of the olfactory epithelium in fish

Abstract

Structural and functional peculiarities of the peripheral part of the olfactory analyzer in fish are considered. The article is devoted to the characteristics of the main types of receptor cells: their morphology, the peculiarities of their location in the olfactory epithelium, and functional specificity. Some data on the threshold values of fish chemosensitivity to chemical agents, which have an important signaling value for them are presented.
