HISTOMORPHOLOGY OF THE NASAL CAVITY IN ONE-HUMPED CAMEL (CAMELUS-DROMEDARIUS)

The histomorphology of the nasal cavity of one-humped camel revealed t hat the nasal glands were compound tubuloalveolar, mixed type, predomi nantly serous in the vestibular region, and simple tubuloalveolar, mos tly mucous type, in the respiratory and olfactory regions. In the caud al vestibular region, they were located deep in the propria submucosa. The blood vessels were distributed in superficial, middle and deep la yers. The arteries were located about the same level with glands in th e nasal vestibule and deep to the glands in other regions. Both thin- and thick-walled veins were present; thin-walled veins were, however, conspicuous in the respiratory and caudal vestibular regions. Goblet c ells were more numerous on the outer surface of the ventral scroll of the ventral nasal concha facing the airstream. Possible role of the na sal glands and blood vessels in cerebral temperature control was sugge sted.
