Upper Respiratory System Multiple Choice Quiz 3 2. If you were giving an oral presentation on olfaction, which of the
following points would you likely include?
a. The process of olfaction begins when signals from the olfactory
area of the cerebral cortex move along the olfactory nerves to the
nasal cavity
b. The process of olfaction begins when neurons in the nasal cavity
receive signals from the olfactory bulbs of the brain.
C. As air enters the nasal cavity, chemicals in the air activate nervous
system receptors on the cilia, sending a signal from the nasal cavity
through the ethmoid bone, olfactory bulbs, and olfactory nerves to
the olfactory area of the cerebral cortex,
d. When air enters the nasal cavity, it stimulates mucus production,
and this mucus triggers signals in the olfactory area of the cerebral
cortex
