30. The olfactory nerves travel through what bone? 31. What is the order of the olfactory nerve pathway? 32. What is smell? 33. Label all olfactory landmarks. 34. What is the anatomical word for taste? 35. True or false: The apex of the tongue is located on the anterior aspect of the mouth. 36. What is a bolus? 37. What type of papillae contain taste buds? 38. True or false: Gustatory cells are the chemoreceptors of the taste buds. 39. What is the purpose of basal cells? 40. True or false: The taste pathway sends signals via only one cranial nerve to the brain. 41. What is anosmia? 42. Review all figures of the gustatory system. 29. Olfactory nerves contain bipolar receptor cells.
30. The olfactory nerves travel through the ethmoid bone through the cribriform plate. 31. Olfactory receptors are activated by airborne chemical substances dissolved in fluid on the surface of nasal mucous membranes. Olfactory nerves (CN i) are bipolar receptor cells found in the olfactory epithelium on the epithelium on the roof of the nasal cavity. The nerves travel through the ethmoid bone where the dendrites extend from the cell body to the surface of the epithelium. Here it terminates in the olfactory bulbs, which are paired masses of gray matter. IN the olfactory bulbs, olfactory nerve axons synapse with other cell bodies of the pathway. The axons travel together from the bulbs to the tracts which carry the information to the temporal lobes. Here it is interpreted in the primary olfaction are a s smell. 32. Smell is defined as a combination of limited primary odors that are detectable by the brain. 33. Olfactory nerves (CN 1), olfactory tract, olfactory bulb, ethmoid bone, cribriform plate, nasal cavity. 34. The anatomical word for taste is gustation. 35. TRUE. The apex of the tongue is located anteriorly. 36. A bolus is a compacted mass of chewed food. 37. The circumvallate and fungiform papillae both contain taste buds. 38. TRUE. Gustatory cells are the chemoreceptors cells inside the taste buds.
39. Basal cells serve as stem cells, which divide and differentiate into new supporting cells that then from new gustatory cells. 40. FALSE. The taste pathway sends signals via two cranial nerve pairs, the facial nerves and the glossopharyngeal nerves. 41. Anosmia is the loss of smell. It is common to have anosmia after a dramatic brain injury. It can also happen gradually like in the case of a growing brain tumor that blocks the olfactory pathway.

Smell is defined as a combination of a limited number of primary odors that are detectable by the brain. 33. See figure in module 34. Gustation (gustatory system) 35. True 36. A compact mass of food, prepared by the tongue and teeth. 37. Circumvallate and fungiform papillae both contain taste buds 38. True 39. Basal cells serve as stem cells, which divide and differentiate into new supporting cells which then form new gustatory cells. 40. False (two nerves- facial and glossopharyngeal) 41. The loss of smell 42. See figures in module Quiz Score: 0 out of 0
