Place the following steps of nerve impulses in the olfaction pathway in order. 
1)primary olfactory cortex in the temporal lobe
2)olfactory nerve

4)olfactory bulb

Quizplus · Accepted Answer

The olfactory neurons, located in the olfactory epithelium in the upper part of the nasal cavity, receive odor molecules and send nerve impulses through the olfactory nerve (2) to the olfactory bulb (4) in the brain. From there, the impulses are transmitted to the primary olfactory cortex (1) in the temporal lobe where odor perception occurs. Therefore, the correct order is 3, 2, 4, 1. This corresponds to answer choice C.
