Chapter 15, Problem 1RAC
Which of these statements is not true with respect to olfaction?
a. Olfactory sensation is relayed directly to the cerebral cortex withoutpassing through the thalamus.
b.Olfactory neurons are replaced about every 2 months.
c.The olfactory cortex is involved in conscious perception of smell.
d.The secondary areas are responsible for visceral andemotional reactions to odors.
e.The olfactory cortex is in the occipital lobe of the cerebrum.
Expert Solution & Answer
Summary Introduction
Introduction:
Olfaction or the sense of smell occurs when the sensory receptor is stimulated in response to the odors. The sensory receptors for the odor are present in the olfactory region which is located at the extreme superior region of the nasal cavity. These olfactory regions are lined with the olfactory epithelium.
Answer to Problem 1RAC
The correct option is e) The olfactory cortex is in the occipital lobe of cerebrum.
Explanation of Solution
Explanation for the correct option:
Option e) The olfactory cortex is in the occipital lobe of the cerebrum. The central olfactory cortex area is located in the temporal and the frontal lobes of the cerebrum and not in the occipital lobe.
Explanation for the incorrect option:
Option a) Olfactory sensation is relayed directly without passing through the thalamus. The olfactory stimuli are processed in the olfactory cortex region of the cerebrum.
Option b) Olfactory neurons are replaced about every two months. The olfactory neurons degenerate and are replaced by the new one in every two months.
Option c) The olfactory cortex is involved in the conscious perception of a smell. The olfactory stimuli perceive the specific odor.
Option d) The secondary olfactory area is responsible for the visceral and emotional reaction to odors. Olfactory stimuli can cause the perception of emotional and autonomic responses. Secondary olfactory areas include the hypothalamus, structure of the limbic system and the hippocampus.

b. The olfactory bulb neurons can modulate output to the olfactory tracts.
c. The olfactory tracts terminate in the sensory and temporal cortex. = sensory should be olfactory
