Smell causes distress and DISCOMFORT, while odour, under DIFFERENT conditions, can be pleasing. The osmogenic molecules (smell) enter the nasal cavity through the nostrils. They excite the osmoceptors. The specific impulse travels along the myelinated nerve fibers to the receptor centres in the brain in the form of specific electric discharges.

The message is. processed and DELIVERED to the evaluation centres in the brain. Here olfactory information is compared with STORED experience (the memory), and finally the interpretation of message is relayed BACK along other nerve paths.
