1. Morphological characterization of the nasopalatine region in human fetuses and its association to pathologies
The nasopalatine region is composed of structures such as the vomeronasal organ and nasopalatine duct. The nasopalatine duct may provide the communication of the mouth to the nasal cavity in human fetuses and can be obliterated in an adult human. Knowledge on the development of the nasopalatine region and nasopalatine duct in humans is necessary for understa

2. Identificação de receptores moleculares para ligantes detectados pelo Órgão Vomeronasal / Identification of molecular receptors for ligands detected by the Vomeronasal Organ
Uma propriedade fundamental do sistema nervoso em todas as espécies animais e a transformação dos estímulos sensoriais em atividade neural, levando a mudanças comportamentais e endócrinas. Dentre os sistemas sensoriais, o Sistema Olfatório destaca-se por sua complexidade molecular, capacidade de detecção de odores e modulação de comportamentos ina

3. Morfometria do órgão vomeronasal em ratos adultos / Morphometric study of the vomeronasal organ in adult rats
The vomeronasal organ of 10 male and 10 female Wistar rats, adults, 120 days weighting between 210 and 318g, were used for this study to determine the histological structure and to verify the existence of sexual dimorphism. After perfusion, the organs were fixed by immersion in 2,5 glutaraldehyde in phosphate-buffered solution; isolated with the nasal septum

4. The vomeronasal organ of the tammar wallaby
The vomeronasal organ is the primary olfactory organ that detects sexual pheromones in mammals. We investigated the anatomy of the vomeronasal organ of the tammar wallaby (Macropus eugenii), a small macropodid marsupial. Pheromones may be important for activation of the hypothalamo-pituitary axis of tammar males at the start of the breeding season because pl

5. The vomeronasal organ of the rat.
The anatomical organization of the vomeronasal complex of the rat (vomeronasal organ blood vessels, cartilage and glands) and the structure of the vomeronasal organ were studied. This organ is a tubular formation that shows different characteristics along its longitudinal axis. In its rostral portion it has a lateral flattened shape but caudally the organ ac

6. The structure of the vomeronasal organ and nasopalatine ducts in Aotus trivirgatus and some other primate species.
A vomeronasal organ and patent nasopalatine ducts were found in adult specimens of Aotus trivirgatus, Arctocebus calabarensis, Ateles geoffroyi and Saguinus fuscicollis. The vomeronasal complex appeared to be functional except in Ateles. However, the relative size of the organ in the Platyrrhini is much reduced compared to that in prosimians. The possible ro

7. Comparative anatomy of the vomeronasal organ complex in bats.
The morphology of the vomeronasal organ complex was histologically described in eight out of fourteen chiropteran species investigated. Of the six families examined, all except the family Pteropodidae (suborder Megachiroptera) were found to have at least one member possessing the organ. The organ is best developed in phyllostomatids. It is absent in vesperti

8. Possible pheromone-carrier function of two lipocalin proteins in the vomeronasal organ.
We report the molecular cloning and characterization of two secretory proteins specifically expressed in vomeronasal and posterior glands of the nasal septum, the ducts of which open into the lumen of the vomeronasal organ. These two proteins are members of the lipocalin superfamily, consisting of hydrophobic ligand carriers. We immunohistochemically localiz

9. The vomeronasal organ of the cat.
The vomeronasal organ of the cat was studied macroscopically, by light microscopy and by immunohistochemical techniques. Special attention was paid to the general distribution of the various soft tissue components of this organ (duct, glands, connective tissue, blood vessels and nerves.) Examination of series of transverse sections showed that the wall of th

10. Anatomical, immnunohistochemical and physiological characteristics of the vomeronasal vessels in cows and their possible role in vomeronasal reception
The general morphology of the vomeronasal vessels in adult cows was studied following a classic protocol, including optical, confocal and ultrastructural approaches. This anatomical work was completed immunohistochemically. The vomeronasal organ in cows is well developed, and its vessels are considerable in size. This fact allowed some functional properties

11. The canine vomeronasal organ.
The vomeronasal organ was studied in mature dogs with the optical, transmission electron, and scanning electron microscopes. The canine vomeronasal complex is structurally well developed. Large blood vessels are present deep to both the lateral, 'non-receptor' and medial, 'receptor' epithelia. In addition to the unmyelinated vomeronasal nerves in the lamina

12. Development of the vomeronasal organ in Rousettus leschenaulti (Megachiroptera, Pteropodidae).
A functional vomeronasal organ (VNO) is known to be lacking in adult bats of the suborder Megachiroptera, family Pteropodidae, studied to date. However, whether the VNO every forms during ontogeny in megachiropterans has not been addressed. We report here on the development of the VNO in megachiropterans via study of 8 stages of rousette fruit bat Rousettus
