The vomeronasal organ (VNO) is a chemosensory organ that functions in sociosexual communication in many vertebrates. In strepsirhine primates and New World monkeys, the bilateral VNOs are traditionally understood to exist as a well‐developed chemosensory epithelial unit. In contrast, the VNOs of catarrhine primates are thought to be absent or exist only as reduced epithelial tubes of uncertain function. However, the VNO of New World monkeys shows substantial variation in the extent of sensory… Expand
Histological definition of the vomeronasal organ in humans and chimpanzees, with a comparison to other primates
TLDR
The vomeronasal organ (VNO) is a chemosensory structure that has morphological indications of functionality in strepsirhine and New World primates examined to date and remarkable morphological/histochemical variability in the VNO and nasopalatine regions among the primate species examined is revealed. Expand
The Vomeronasal Organ of New World Monkeys (Platyrrhini)
TLDR
Microanatomical findings indicate that some lineages of New World monkeys may have a reduced or vestigial vomeronasal system, supporting the hypothesis that some platyrrhines may have delayed maturation of the VNO. Expand
The human vomeronasal organ. Part VI: A nonchemosen sory vestige in the context of major variations of the mammalian vomeronasal organ
A vomeronasal organ (VNO) is found in most extant a mphibians, reptiles, and mammals, but is absent in extant archosaurs (birds and croco dilians). In amniotes, the VNO differs greatly from its basalExpand
The Vomeronasal Complex of Nocturnal Strepsirhines and Implications for the Ancestral Condition in Primates
TLDR
Results indicate that nocturnal strepsirhines have basic similarities to rodents in growth and maturational characteristics of VSNs, and given that osteological features such as the VNG are visible on midfacial bones, primate fossils can be assessed to determine whether primate ancestors possessed a vomeronasal complex morphologically similar to that of modern nocturnes. Expand
Ontogenetic characteristics of the vomeronasal organ in Saguinus geoffroyi and Leontopithecus rosalia, with comparisons to other primates.
TLDR
The findings indicate that tamarins have delayed maturation of the VNO epithelium, and that some species have little or no perinatal function, as well as suggesting that ontogenetic changes in craniofacial form may alter the position of the vomeronasal organ inTamarins. Expand
The vomeronasal organ of Lemur catta
TLDR
The VNO of L. catta is shown to be microanatomically comparable to that of nocturnal strepsirrhines, and numerous taste buds present at the oral opening to the nasopalatine duct provide an additional (or alternative) explanation for the flehmen behavior that has been observed in this species. Expand
Observations on the vomeronasal organ of prenatal Tarsius bancanus borneanus with implications for ancestral morphology
TLDR
Pregnant similarities exist in Tarsius and New World primates in VNO epithelial morphology, and these are transient stages of morphology, suggesting that tarsiers and anthropoids do represent a clade (Haplorhini), then the atypical morphology seen in adult tarsier and NewWorld monkeys probably represents the adult VNO morphology of a haplorhine common ancestor. Expand
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. Expand
Comparative study of lectin reactivity in the vomeronasal organ of human and nonhuman primates.
TLDR
The overall pattern of lectin reactivity in the human and chimpanzee VNO is unlike that seen in mammals with chemosensory VNOs, suggesting that the VNO of these hominoids does not function similarly to that of other primates. Expand
RESEARCH ARTICLE The Vomeronasal Organ of Lemur catta
TLDR
The VNO of L. catta is shown to be microanatomically comparable to that of nocturnal strepsirrhines, and numerous taste buds present at the oral opening to the nasopalatine duct provide an additional (or alternative) explanation for the flehmen behavior that has been observed in this species.

The existence of the vomeronasal organ in postnatal chimpanzees and evidence for its homology with that of humans
TLDR
The results demonstrate that the VNO is present postnatally in the chimpanzee and is almost identical to the human VNO in its anatomical position and histological structure, which suggests that the reported absence of theVNO in at least some adult Old World primates is artifactual, and that further study may provide evidence for its existence in other species.

Comparative morphology and histochemistry of glands associated with the vomeronasal organ in humans, mouse lemurs, and voles
TLDR
Unique characteristics of the human VNO which at once differs from glandular ducts and cilia are demonstrated and also from the VNOs of mammals possessing demonstrably functional VNO. Expand
Vomeronasal organ in bats and primates: Extremes of structural variability and its phylogenetic implications
TLDR
The general phylogenetic implications based on the cladistic analysis of bats are that the vomeronasal organ complex has evolved several times, and among the prosimians and platyrrhine primates, the organ is well developed, although to a varying degree. Expand
Development of the vomeronasal organ in Rousettus leschenaulti (Megachiroptera, Pteropodidae).
TLDR
A conclusion that a VNO is entirely lacking in Megachiroptera seems reasonable, however, final confirmation awaits study of the additional 27 genera not yet reported (out of a total of 41). Expand

TLDR
This review will discuss immunohistochemical studies that have identified features in the mammalian VNS, and relate them to structural and IHC studies of the fetal and adult human VNS. Expand
Comparative anatomy of the vomeronasal organ complex in bats.
TLDR
The desirability of extending the useful terms 'diosmatic' and 'monosmatic' to all vertebrates in reference to their respective possession or lack of the vomeronasal organ is suggested. Expand

The hypothesis that VNNE size is associated negatively with the level of parental care by male voles is not supported, which likely includes an interaction of the genome, behavior, and environment. Expand

TLDR
A phenotypic classification schema for the human vomeronasal organ is described and applied to 253 human subjects who underwent nasal examination and there is no evidence supporting involutional senescence of this structure. Expand
