All of the options are correct. Olfactory receptors are specialized endings of afferent neurons located in the olfactory mucosa. When stimulated, they send impulses both to the limbic system for coordination between smell and behavior and to the thalamus and cortex for perception of smell. They are replaced about every two months.
