The vomeronasal organ plays an important role with its sensitivity toward chemicals that are related to mating or sensing prey. For example, snakes use the organ to detect the presence of prey or predator by gathering chemical cues in the environment through the flicking behavior of the forked tongue. Garter snakes also use the vomeronasal ...
[33] [34] Most have sought to identify the opening of the vomeronasal organ in humans, rather than identify the tubular epithelial structure itself. [35] Thus it has been argued that such studies, employing macroscopic observational methods, have sometimes missed or even misidentified the vomeronasal organ. [36]
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. The vomeronasal organ is named for its closeness to the vomer and nasal bones, and is particularly well developed in animals such as cats ...
An inherent difficulty in studying human pheromones is the need for cleanliness and odorlessness in human participants. [3] Experiments have focused on three classes of putative human sex pheromones: axillary steroids, vaginal aliphatic acids and stimulators of the vomeronasal organ.
Pheromones have evolved in all animal phyla, to signal sex and dominance status, and are responsible for stereotypical social and sexual behaviour among members of the same species. In mammals, these chemical signals are believed to be detected primarily by the vomeronasal organ (VNO), a chemosensory organ located at the base of the nasal ...
The part of a rabbit’s brain used to process scents is also significantly larger than that of a human’s. Rabbits have a specialized organ called the Jacobsen’s organ, or the vomeronasal ...
In vertebrates, the accessory olfactory bulb (AOB), which resides on the dorsal-posterior region of the main olfactory bulb, forms a parallel pathway independent from the main olfactory bulb. The vomeronasal organ sends projections to the accessory olfactory bulb [15] [16] making it the second processing stage of the accessory olfactory system ...
[23] [41] [42] [43] Currently, no structure of the vomeronasal organ has been elucidated in Old World monkeys, although it has been shown that an apparent vestigial vomeronasal organ develops but degenerates before birth. [23] Conversely, human embryos possess a vomeronasal organ that persists, although this feature is vestigial throughout ...
