Question 1: Which of the following is true of olfactory discrimination?

• There are 6 primary smells known.
• The number of olfactory receptors decline as we age.
• All odorants require the same concentration to activate an olfactory receptor.

Answer:

• The number of olfactory receptors decline as we age.

Question 2: The olfactory receptors are highly modified

• epithelial cells.
• interneurons.
• sensory neurons.
• motor neurons.
• neuroglial cells.

Answer:

• sensory neurons.

Question 3: As we age

• taste bud sensitivity increases.
• taste bud sensitivity doubles.
• the number of taste buds increases.
• the number of taste buds decreases.

Answer:

• the number of taste buds decreases.

Question 4: During a sinus infection it is difficult to smell because

• basal cell division decreases.
• olfactory glands stop producing mucus.
• excess mucus blocks odorant molecules from reaching the receptors.

Answer:

• excess mucus blocks odorant molecules from reaching the receptors.

Question 5: Which of the following correctly states how a gustatory receptor will be stimulated by an acidic or sour compound?

• G proteins will be activated.
• Sodium ions will diffuse into the receptor cell causing depolarization.

Answer:

• Sodium ions will diffuse into the receptor cell causing depolarization.

Question 6: All of the following are true of olfactory pathways except which one?

• They project first to the occipital lobes and then to the thalamus.
• Neurons from the olfactory epithelium synapse in the olfactory bulb.

Answer:

• They project first to the occipital lobes and then to the thalamus.

Question 7: Olfactory glands

• house the sense of smell.
• regenerate to form new olfactory epithelium.
• react to aromatic molecules.
• coat the olfactory epithelium with a pigmented mucus.
• group as olfactory bulbs.

Answer:

• coat the olfactory epithelium with a pigmented mucus.

Question 8: Some neural tissues retain stem cells and thus the capacity to divide and replace lost neurons. Which of these special senses can replace its damaged neural receptors?

• olfaction
• hearing
• equilibrium
• proprioception
• vision

Answer:

• olfaction

Question 9: Olfactory receptors send axons through the cribriform plate. They synapse on neurons in the

• medulla oblongata.
• medial geniculate.
• cerebral cortex.
• olfactory bulb.
• olfactory tract.

Answer:

• olfactory bulb.

Question 10: Which of the following types of sensory information reaches the cerebral cortex directly?

• visual
• hearing
• equilibrium
• olfactory
• gustatory

Answer:

• olfactory

Question 11: Which of the following lingual papillae has the largest number of taste buds?

• pharynx
• foliate papillae

• fungiform papillae
• vallate papillae

Answer:

vallate papillae Question 12: Olfactory information is first received by which part of the brain?

• pons
• cerebellum
• thalamus
• cerebrum
• medulla oblongata
