Development, evolution, and functional significance of the vomeronasal organ

Abstract

The sensory organs transmit physical (vision, hearing, and touch) or chemical (smell and taste) signals. In particular, the chemoreceptors of the respiratory epithelium are anatomically connected with the structures of the limbic system and therefore contribute to the formation of emotions, memories, and behavior. The cortical end of the olfactory analyzer is located in the hippocampal gyrus (Ammon’s horn). Parallel to the olfactory system, there exists the vomeronasal system, or the vomeronasal organ (VNO). The aim of the study. To investigate the development, evolution, and functional significance of the vomeronasal organ in humans and certain animals, and to outline prospects for further research. Materials and methods. The work presents a scientific analysis of data from original research publications concerning the morphology, evolution, and physiology of the vomeronasal organ.
