Question

These are approximately _________ odor-detecting cells located high in each nasal cavity.

a) 5,000
b) 10,000
c) 50,000
d) 100,000

Answer 1

Approximately 5,000 to 10,000 odor-detecting cells are located high in each nasal cavity.

Step-by-step explanation:

The approximate number of odor-detecting cells located high in each nasal cavity is 5,000 to 10,000. These cells are known as olfactory receptors, which are specialized neurons. Humans have about 12 million olfactory receptors, distributed among hundreds of different receptor types that respond to different odors. Rats have approximately 1,200 genes coding for olfactory receptors, while dogs have around 800 genes.
