Abstract
The human vomeronasal organ (OVN) is a structure that is once studied in Anatomy, but commonly little is known about its location, frequency and specific function. For this reason recent literature on the subject was reviewed, emphasizing important topics such as its anatomy and relation to some behaviors. The vomeronasal organ is nowadays considered an accessory olfactory organ, capable of detecting the presence of vomeropherins. These belong to a group of identified chemical substances, capable of induce behavioral changes at the social, sexual and maternal level. It is located lateral to the nasal septum, and it contains peripheral cells that act as receptors, which upon stimulation are capable of triggering a response that can be recorded via an electrode located in the vomeronasal epithelium. In addition, recent studies suggest that the vomeronasal organ has a direct connection to the central nervous system, by way of bipolar sensory neurons, which would demand additional care in patients having surgery in its vicinity.
