Olfactory mucosa

Olfactory mucosa is found in the nasal mucosa - in a small region of the roof of the nasal cavities.

It is here where there are receptors for sense of smell.

The cells coloured yellow in the diagram are the olfactory receptor cells. These are bipolar neurones.

questionWhat do you think the function of the modified cilia on the apical surfaces of the receptor cells are for?

(Hint - these are non-motile - and are flattened onto the epithelial surface).
