Question 2 Your answer is CORRECT. Why are we able to differentiate tastes and smells? A) The action potentials initiated by taste receptors are transmitted to a separate region of the brain than those initiated by receptors for smell. B) The sensory region of the cerebral cortex distinguishes something we taste from something we smell by the difference in the action potential. C) The brain distinguishes between taste, arising from interoreceptors, from smell arising from exteroreceptors. D) Because we are able to see what we are tasting, the brain uses this information to distinguish taste from smell. E) Taste receptors are able to detect fewer molecules of the stimulus, which means these receptors will initiate a receptor potential before smell receptors do.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
