The axons of the olfactory receptors run through the

D) cribriform plate to the olfactory bulbs.
E) olfactory epithelium to olfactory cortex.

Question

Quizplus · Accepted Answer

The axons of the olfactory receptors run through the cribriform plate and then into the olfactory bulbs, where they synapse with neurons that transmit the information to other areas of the brain, including the paleocortex (option B is partially correct, but doesn't include the first stop of the axons in the olfactory bulbs). The thalamus is not directly involved in the olfactory pathway, so options A and C are incorrect. Option E is also incorrect as it doesn't include the olfactory bulbs as a necessary step in the pathway.
