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. [1]

We were curious to know whether such a septal pit corresponds to the opening of the vomeronasal organ (VNO or Jacobson’s organ). The VNO is an accessory olfactory sense organ inside the nose of most amphibia, reptiles and mammals which detects specific chemical compounds, including pheromones [8].

犁鼻器（Vomeronasal organ VNO）是在鼻腔前面的一对盲囊，开口于口腔顶壁的一种化学感受器。 通过研究，科学家认定感觉外激素的器官叫作犁鼻器，这是一个位于鼻中隔底部的软骨结构。

The VNO is located on both sides of the lower part of the nasal septum. The essential structure therein is the vomeronasal sensory epithelium (VNSE) containing vomeronasal receptor neurones (VRNs) whose axons leave the VNSE, coalesce along the nasal septum to form the vomeronasal nerve entering the cranial cavity, and synapse in a distinct part ...

The human vomeronasal organ (VNO) is an accessory olfactory organ located on the anteroinferior part of the nasal septum, 1.5-2.5cm from the nostrils. Its main role is pheromone reception and, through its anatomical connections with the central nervous system, especially parts of the hypothalamus, m …

2011年10月10日 · The vomeronasal organ (VNO) plays a key role in mediating the social and defensive responses of many terrestrial vertebrates to species- and sex-specific chemosignals 1. Over 250 putative pheromone receptors have been identified in the mouse VNO 2,3, but the nature of the signals detected by individual VNO receptors has not yet been elucidated ...

Objective: To find out whether the vomeronasal organ (VNO) can be identified in the nose as a mucosal pit in the anterior nasal septum, to elucidate its function in man and to determine whether it is important to preserve the VNO during septal surgery.

The vomeronasal organ (VNO) is essential for intraspecies communication in many terrestrial vertebrates. The ionic mechanisms of VNO activation remain unclear. We found that the calcium-activated potassium channel SK3 and the G protein–activated potassium channel GIRK are part of an independent pathway for VNO activation.

1998年11月30日 · Recent publications show that the human vomeronasal organ (VNO) develops and grows during gestation, and is present in all adult humans. The human VNO has a unique ultrastructure, with elongated bipolar microvillar cells that stain with several immunomarkers.

1991年10月1日 · These investigations address three major questions: (1) What is the frequency of occurence of the vomeronasal (Jacobson's) organ (VNO) in man? (2) what is the ultrastructure of the human VNO? and (3) does the VNO contain sensory receptor cells?
