The vomeronasal organ (VNO), or Jacobson's organ, is the paired auxiliary olfactory (smell) sense organ located in the soft tissue of the nasal septum, in the nasal cavity just above the roof of the mouth (the hard palate) in various tetrapods.
Jacobson’s organ, an organ of chemoreception that is part of the olfactory system of amphibians, reptiles, and mammals, although it does not occur in all tetrapod groups. It is a patch of sensory cells within the main nasal chamber that detects heavy moisture-borne odour particles.

May 17, 2018 · In humans, the vomeronasal organ (VNO), also known as (Jacobson’s) organ is an accessory olfactory organ situated on the anteroinferior third of the nasal septum [ 1 ]. It consists of a blind sac with a duct opening anteriorly, both supplied with a rich vascular and glandular network.
Aug 6, 2018 · In mammals, Jacobson's organ is used not simply to identify minute quantities of chemicals, but also for subtle communication between other members of the same species, through the emission and reception of chemical signals called pheromones.
Jun 1, 2021 · In this video, we explore the mechanism of pheromones by examining the structure, function, and pathway to the brain for Jacobson’s organ aka the vomeronasal organ.
The vomeronasal organ (or Jacobson's organ) is a paired tubular diverticulum located in the vomer bone in the ventral portion of the proximal nasal septum of most mammals. Like the olfactory epithelium, it is a chemosensory structure that contributes to the sense of smell, in macrosmotic species (e.g., laboratory rodents, dogs, rabbits).
May 11, 2000 · Jacobson's organ is an anatomical structure lying in the nasal septa of a wide range of animals. It is named after Ludwig Levin Jacobson, an eighteenth-century Danish army surgical officer...

Aug 21, 2017 · Jacobson ( 1811) studied the VNO intensively across a variety of mammals, although he denied its existence in humans. Consequently, VNO is now also known as “Jacobson's organ,” largely due to Potiquet ( 1891 ), who supplied the first extensive discussion of the VNO in humans.
Review The Human Vomeronasal (Jacobson's) Organ: A Short Review of Current Conceptions, With an English Translation of Potiquet's Original Text.
The vomeronasal organ (VNO) is a complex of different structures that forward specific chemical signals commonly called pheromones to the central nervous system. In some macrosmatic animals, e.g. rodents, the VNO consists of vomeronasal receptor neurons located in a sensory epithelium of the vomeron ….
