Zusammenfassung: | The accessory olfactory bulb (AOB) is the primary target of the sensory epithelium of the vomeronasal
organ (VNO), and thus constitutes a fundamental component of the accessory olfactory system, which is
involved in responses to behaviour-related olfactory stimuli. In this study we investigated the characteristics
of the AOB, VNO, vomeronasal nerves (VNNs) and caudal nasal nerve (CdNN) in pigs and sheep, species
in which olfaction plays a key behavioural role both in the neonatal period and in adulthood. The patterns
of staining of the AOB by the Bandeiraea simplicifolia and Lycopersicon esculentum lectins were the same in
the 2 species, whereas the Ulex europeus and Dolichos biflorus lectins gave different patterns. In both species,
lectin staining of the AOB was consistent with that of the VNNs, while the CdNN did not label any of the
structures studied. The entire sensory epithelium of the pig was labelled by Ulex europeus and Lycopersicum
esculentum lectins, and all 4 lectins used labelled the mucomicrovillar surface of the sensory epithelium in
sheep. |
