Light and scanning electron microscopy of the olfactory mucosa in the rufous sengi (Elephantulus rufescens)

Summary Sengis are eutherian insectivores belonging to superorder Afrotheria, a recently defined clade of mammals that diverged from other placentals over 100 million years ago. In this study, a histological and ultrastructural analysis was carried out on the olfactory mucosa (OM) of the rufous seng...

Description
Summary:Summary Sengis are eutherian insectivores belonging to superorder Afrotheria, a recently defined clade of mammals that diverged from other placentals over 100 million years ago. In this study, a histological and ultrastructural analysis was carried out on the olfactory mucosa (OM) of the rufous sengi (Elephantulus rufescens) and the data were compared with those reported earlier in the dog (Canis familiaris) and the sheep (Ovis aries), whose dietary lifestyles are carnivorous and herbivorous, respectively. Qualitatively, the microstructure of the sengi's OM was basically similar to that of the other eutherian mammals except for differences in the pattern of cilia projection from the dendritic knobs of the olfactory receptor neurons (ORNs) and distribution of Bowman's glands within the lamina propria of the OM. On morphometry, significant differences (p
