The current study was carried out to investigate histological features of olfactory bulb were observed in cats, 12 samples (n = 12) were used. six samples for anatomical observation of olfactory bulb were record in adult cats which involved the morphological study (position, relation, weight, length and diameter), he length of the olfactory bulb was of greatest value in cats (19.5 ±0.72). The greatest width (diameter) of olfactory bulb relative to that of the corresponding cerebral hemisphere gave the highest ratio in the cats (41.92%),
The olfactory bulbs were Fixed in 10% formalin solution then processed in routine histological technique which stained with Hematoxylin & Eosin and Mallory stains. The morphological result of olfactory bulb in cats showed was semicircular in shape with a ventrolateral rough surface Meanwhile. creamy in color that located in the fore brain of vertebrates which receives neural input about odors detected by cells in the nasal cavity.
Histologically the histological section of the olfactory bulb of a cats, there are four distinct layers that may be identified: (olfactory nerve layer, glomerular layer, mitral cells layer, and granule cells layer).
In the present study, olfactory bulbs of greyhound and outdoor cat were ccrrcered histologically. Was loud that the olfactory bulbs of both species were instituted by accessory and main parts having the same layers (nerve. glomerular, external plexiform, mitral cell, internal plexiform and granular cell). Nerve. glomerular and mitral cell layers were very wide and there were many glial cell in the test two layers in the olfactory bulbs of greyhound.
However, in outdoor cat, these layers were very narrow and titer were few mitral and glial cells. Differences in the smiling ability between greyhound and outdoor cat were thought to be depended on the histomorphological diltererces of their olfactory bulbs.
