In many terrestrial tetrapodes, a pair of vomeronasal organs (VNOs), which are chemosensory apparatuses, are situated at the base of the nasal septum in the anterior nasal cavity. The purposes of this review are to summarize comparative neuroanatomy and to introduce recent progress in neurobiological studies of the VNO. Five types of VNOs can be identifiable in terms of anatomical organization; snakes possess the most complex one. Sensory cells in the VNO, vomeronasal receptor neurons (VRNs… 

Mechanisms underlying pre- and postnatal development of the vomeronasal organ

TLDR
Current understanding of cellular and molecular mechanisms that underlie VNO development are summarized and open questions for study are discussed, which are suggested to further enhance the understanding of VNO morphogenesis at embryonic and postnatal stages.

Structure and function of the vomeronasal organ.

TLDR
Recent studies indicate that pheromone-like compounds are most likely registered at the level of olfactory receptor cells, rendering the chemical information system more independent of specific organ structures.

Vomeronasal Receptors and Signal Transduction in the Vomeronasal Organ of Mammals

TLDR
The anatomical components of the VNO firstly developed in a tetrapod ancestor and led to the appearance of a rudimentary structure in amphibians that became highly organized in Squamata and in many mammalian orders as Didelphimorphia, Rodentia, and in primates (prosimians and New World monkeys).

A detailed morphological study of the vomeronasal organ and the accessory olfactory bulb of cats

The organization of the vomeronasal system (VNS) of fetal, newborn, and adult cats was investigated by microdissection and microscopic examination of sections stained conventionally or with lectins

Morphological and Immunohistochemical Features of the Vomeronasal System in Dogs

Each of the structures integrating the sense of smell in mammals has a different degree of development, even in the so‐called macrosmatic animals, according to the capacity of the olfactory system to

Origin and evolution of the vertebrate vomeronasal system viewed through system‐specific genes

TLDR
It is proposed that a VNS precursor exists in teleosts and that its evolutionary origin predated the separation between teleostS and tetrapods.

Immunohistochemistry of the canine vomeronasal organ

TLDR
It is demonstrated that the canine vomeronasal organ contains a population of cells that expresses several neuronal markers and GAP43 immunoreactivity suggests that the sensory epithelium is neurogenic in adult dogs.

Diversity of the vomeronasal system in mammals: The singularities of the sheep model

TLDR
It is determined that all structures which classically define the VNO in mammals are present and well developed, providing the morphological basis for functional activity and that the strata of the AOB in adult sheep are not as sharply defined as in other species.

The vomeronasal organ and associated structures of the fetal African elephant, Loxodonta africana (Proboscidea, Elephantidae)

TLDR
The development of the VNO and its associated structures in the African elephant are described in detail using serially sectioned material from fetal stages, and the unique characteristics of the elephant VNO are confirmed, such as its large size, the folded epithelium of theVNO tube, andThe dorsomedial position of the neuroepithelium.
