Vomeronasal Organ
Research News and Information
Definition of 'Vomeronasal Organ'An accessory chemoreceptor organ that is separated from the main OLFACTORY MUCOSA. It is situated at the base of nasal septum close to the VOMER and NASAL BONES. It forwards chemical signals (such as PHEROMONES) to the CENTRAL NERVOUS SYSTEM, thus influencing reproductive and social behavior. In humans, most of its structures except the vomeronasal duct undergo regression after birth. Common names: Vomeronasal Organ; Vomeronasal Organs; Jacobson's Organ; Jacobsons Organ; Organum Vomeronasale; Organum Vomeronasales; Vomeronasale, Organum; Jacobson Organ; Vomeronasal System; Vomeronasal Systems; Vomeronasal Nerve; Vomeronasal Nerves |

Conserved repertoire of orthologous vomeronasal type 1 receptor genes in ruminant species.
13 Sep 2009 
BACKGROUND: In mammals, pheromones play an important role in social and innate reproductive behavior within species. In rodents, vomeronasal receptor type 1 (V1R), which is specifically expressed in the vomeronasal organ, is thought to detect ... Read more...
Pheromone signal transduction in humans: what can be learned from olfactory loss.
30 Aug 2009 Because humans seem to lack neuronal elements in the vomeronasal organ (VNO), many scientists believe that humans are unable to detect pheromones. This view is challenged by the observations that pheromone-like compounds, 4,16-androstadien-3-one ... Read more...
Bestrophin 2: an anion channel associated with neurogenesis in chemosensory systems.
8 Aug 2009 The chemosensory neuroepithelia of the vertebrate olfactory system share a life-long ability to regenerate. Novel neurons proliferate from basal stem cells that continuously replace old or damaged sensory neurons. The sensory neurons of the mouse ... Read more...
