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.
The flehmen response draws air into the vomeronasal organ (VNO), an auxiliary olfactory sense organ that is found in many animals. This organ plays a role in the perception of certain scents and pheromones.
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.
Nov 1, 1998 · In 1813, the Danish anatomist Ludvig Jacobson (1783–1843) described an organ in the nose of mammals that had not been noticed previously. He meticulously observed the many glands of the organ, the dual innervation and the blood supply ( Jacobson, 1813 ).
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.
