Human 15 weeks - terminal nerve and vomeronasal organ nerves

The terminal nerve and nerves to the vomeronasal organ (VNON) are separated by a developing nasal septum in a specimen of crown rump length 110 mm (15 weeks). Sagittal sections. Immunohistochemistry of S100 protein (S100) (A, C) or calretinin (cal) (D). (B) Hematoxylin and eosin staining. Panels C and D display the vomeronasal organ (VNO) and VNON in the other side of panels A and B. Intervals between panels are 0.2 mm (A–B), 0.6 mm (B–C), and 0.1 mm (C–D). In panel A, the terminal nerve (NT) runs along the posterior aspect of the cartilaginous nasal bone, while the VNON run along the palate near the VNO. Thus, these nerves are separated by a developing nasal septum. Scale bars=1 mm (A–D).
