Question

The sense of smell is different from the other senses in that its sensory pathways are ____________________________.

Answer 1

The olfactory neuronal pathway is unique in that it goes directly to the limbic system and cerebral cortex rather than going through the thalamus first.

So ans is not routed directly through the thalamus.

Answer 2

Answer:

The correct answer is - not routed directly through the thalamus.

Explanation:

Olfaction is a chemical receptor that is bound to odorant to initiate a sense of smell. The olfactory system is related to the sense of smell. This chemoreceptor of smell not routed through the thalamus as thalamus not contacted in between the olfactory bulb to the cortex which is the route of the signal id.

This is the major difference between other senses like taste to the sense of smell.

Thus, the correct answer is - not routed directly through the thalamus.
