Question
### Sensory Receptors and Taste Pathways #### QUESTION 19 *Identify the similarity between sweet receptors and bitter receptors. Choose the correct option.* **Options:** - A. Both are G-protein-coupled receptors - B. Both are expressed in the same taste cell - C. Both stimulate the same gustatory axon - D. Both use T1R2 and T1R3 receptor proteins #### QUESTION 20 *Identify which of the following best describes the central taste pathways. Choose the correct option.* **Options:** - A. Axons of all 12 cranial nerves terminate in the gustatory nucleus of the brain stem, which projects to the ventral posterior medial nucleus of the thalamus, which in turn sends axons to the primary gustatory cortex and the insula - B. Axons of three cranial nerves terminate in the gustatory nucleus of the brain stem, which projects to the ventral posterior medial nucleus of the thalamus, which in turn sends axons to the primary gustatory cortex and the insula - C. Axons of three cranial nerves terminate in the gustatory nucleus of the brain stem, which projects to the ventral posterior medial nucleus of the thalamus, which in turn sends axons to Brodmann's area 18 and the insula - D. Axons of all 12 cranial nerves terminate in the ventral posterior medial nucleus of the thalamus, which in turn sends axons to Brodmann's area 18 and the insula *Instructions for submission:* Click 'Save and Submit' to save and submit.
