Structure of Vomeronasal Organ (Jacobson) in the Male Red Fox (Vulpes Vulpes)
Introduction: Most mammalians possess an accessory olfactory system, which its first part is called vomeronasal organ (VNO). In this research, we studied the structure of this organ in Azerbaijani red fox. Methods: Heads of 10 healthy male fox carcasses were collected from areas around Tabriz and transferred to the laboratory in frozen form or in fixative solution. Biometrical e...

متن کاملAlarm pheromone is detected by the vomeronasal organ in male rats.
It is widely known that a stressed animal releases specific pheromones, possibly for alarming nearby conspecifics. We previously investigated an alarm pheromone in male rats and found that this alarm pheromone evokes several responses, including increases in the defensive and risk assessment behaviors in a modified open-field test, and enhancement of the acoustic startle reflex. However, the ro...
متن کاملThe structure of the nasal chemosensory system in squamate reptiles. 2. Lubricatory capacity of the vomeronasal organ.
The vomeronasal organ is a poorly understood accessory olfactory organ, present in many tetrapods. In mammals, amphibians and lepidosaurian reptiles, it is an encapsulated structure with a central, fluid-filled lumen. The morphology of the lubricatory system of the vomeronasal organ (the source of this fluid) varies among classes, being either intrinsic (mammalian and caecilian amphibian vomero...
متن کاملVomeronasal Organ: Pheromone Recognition with a Twist
Pheromones are detected by the vomeronasal organ using members of two receptor superfamilies: the V1Rs and V2Rs. New studies show that MHC class I molecules are co-expressed in particular combinations with specific V2Rs in the vomeronasal organ. The role of these MHC molecules is unknown, but they may be of considerable biological significance.
