Nasal septum
Nasal mucosa
Throughout the nasal cavity. Respiratory epithelium with goblet cells. Sero-mucous glands in the lamina propria. Dilated venules and veins.
Olfactory mucosa
Limited to a small area on the roof. Taller epithelium with no goblet cells. (Only) serous glands (Bowman’s) in the lamina propria. Dilated venules and veins.
