Macroscopic cross sectional study of the nasal cavity of the wolf. (a) Lateral view of the head of the wolf showing the eight consecutive levels chosen for the macroscopic sectional study. (b) The central part of the vomeronasal organ (VNO) is located at level 6 (yellow line in “a”, enlarged section in “b and d”). The VNO corresponds to two tubular structures located in the ventral part of the nasal septum (black arrows), lateral to the vomer bone (asterisk) and ventral to the cartilage of the nasal septum (circle). (c) Transverse sections of the nasal cavity ordered from rostral (1) to caudal (8), corresponding to the levels represented in (a). (d) At higher magnification, it can be seen how the VNO is enveloped by a cartilaginous capsule (arrowheads). In the central part of the VNO, the vomeronasal ducts can be observed. CT, canine tooth; DT, dorsal turbinate; NS, nasal septum; VT, ventral turbinate.
