Ultrastructure of the human vomeronasal organ
The Journal of Steroid Biochemistry and Molecular Biology, 1991Virtually all vertebrates have a vomeronasal system whose involvement in pheromone detection plays a crucial role in reproduction. In humans, the vomeronasal organ has been assumed to be vestigial or absent and without functional significance. In the present study involving over 400 subjects, vomeronasal pits were observed in all individuals except ...

The vomeronasal (VN) organ of Jacobson is the receptor organ of the accessory olfactory system (AOS). The VN organ consists mainly of an olfactory epithelium (OE) and a vascular pump. The OE is characterised by the presence of primary receptor neurons whose axons form the VN nerve and contact the secondary neurons in the AO bulb (AOB). Hence the neural

Organization of the vomeronasal organ in a plethodontid salamander
Journal of Morphology, 1988AbstractSalamanders in the family Plethodontidae show a unique behavior (nose‐tapping) and have unique structures (nasolabial grooves) that may be used specifically to convey chemicals to the vomeronasal organ. The nasal structure of Plethodon cinereus was studied to determine if there is enhanced development of the vomeronasal organ compared with ...

The Vomeronasal Organ of the Male Ferret
Chemical Senses, 1999The vomeronasal organ (VNO) is known to play a major role in sexual behavior in many mammals. This study is the first report that the adult male ferret has a VNO, which is considerably smaller and morphologically different from the usually crescent-shaped epithelium in several mammalian species, particularly rodents.

Pheromone transduction in the vomeronasal organ
Current Opinion in Neurobiology, 1996Single-cell physiology and cloning efforts have extended studies of the vomeronasal organ to cellular and molecular levels. Recent work has shown that transduction in the vomeronasal organ is probably mediated by signalling pathways distinct from those that mediate transduction in the main olfactory system.

Prenatal development of the mammalian vomeronasal organ
Microscopy Research and Technique, 1998The vomeronasal organ (VNO) originates from the medial wall of the olfactory pit shortly after the middle of the embryonic period in mammals. The Anlage stage consists of a cellular bud that grows dorsally, caudally, and towards the midline leaving a groove.

The vomeronasal organ of Lemur catta
American Journal of Primatology, 2014The vomeronasal organ (VNO), also known as the Jacobson's organ, is a bilateral chemosensory organ found at the base of the nasal cavity specialized for the detection of higher‐molecular weight (non‐volatile) chemostimuli. It has been linked to pheromone detection.

[The human vomeronasal organ].
Der Nervenarzt, 2004Odors influence human behavior. The perception of so-called pheromones is frequently mentioned in the context of a functional vomeronasal organ. Vomeronasal ducts can be detected in approximately half of the population. Its functionality, still a matter of debate, seems to be unlikely, at least after birth.

Structure and function of the vomeronasal organ
Journal of Experimental Biology, 1998ABSTRACT Many animals use their vomeronasal organs to gain direct and specific contact with chemical cues released by congeners and in biological fluids. These cues provide information about the physiological status of the emitter and facilitate or regulate social interactions such as sexual relationships.

The vomeronasal organ was studied in mature dogs with the optical, transmission electron, and scanning electron microscopes. The canine vomeronasal complex is structurally well developed. Large blood vessels are present deep to both the lateral, 'non-receptor' and medial, 'receptor' epithelia.
