WebThe sensory messages are interpreted in the frontal lobe. Which of the following represents the pathway for smell in the correct order? A. Bipolar neuron → CN I → temporal lobe → hypothalamus and amygdala. **. B. Bipolar neuron → CN I → temporal lobe → frontal lobe. C. Both a and b are correct. D. Neither a nor b is correct. WebThe electrical message from a taste receptor goes directly to the terminal of a primary taste sensory neuron (Figure 2), which is in contact with the receptor cell right in the taste bud. The cell bodies of these neurons are in the brainstem (lower part of the brain, below the cerebrum and their axons form pathways in several cranial nerves. meghdoot chemicals ltd
