Abstract:
Morphological features of ethmoturbinates were studied in two frozen heads in five (5) transverse sections of nasal cavity and two heads sectioned longitudinally with intact nasal septum on which impressions of ethmoturbinates were seen. Ethmoturbinates were in two groups viz., 4–6 lateral ectoturbinates and seven medial Endoturbinates (EnTI – VII) anchored to convex nasal surface of cribriform plate. First EnT was longest and broadest (7.18 and 1.89 cm) extending into nasal cavity, whereas EnT II was second largest at level of upper last molar followed by next two connected by a common stalk. Ethmoturbinates at level of third upper molar displayed ethmoidal labyrinth in rostro-caudal direction whose ventral ends were attached to ventro-lateral plate inclined towards nasal septum. Present study shows seven well developed EnT in caudal third of nasal cavity in pigs.
