The human nose can distinguish up to 10 000 different odours. Airborne odour
molecules are trapped by ciliated olfactory receptors. These receptors initiate impulses
to the olfactory bulbs, which relay the signals to the temporal lobe of the cerebrum for
interpretation.
29. Olfactory receptors are categorized as
a. mechanical receptors that are attached to the dendrites of neurons
b. mechanical receptors that are attached to the axons of neurons
c. chemoreceptors that form a synapse with dendrites of neurons
d. chemoreceptors that form a synapse with the axons of neurons
