Question

Which two of the following are part of the olfactory organs? a. olfactory receptor cells b. columnar epithelial cells in the nasal mucosa c. the brain d. the eyes

Expert Solution

Step 1

The sensory system that comprises various organs and helps us provide the sense of smell (olfaction) is called the olfactory system. The olfactory system present in various mammals and reptiles is divided into a main and an accessory olfactory system.

Step 2

The sensory organ in the facial region called the nose helps in olfaction. The olfactory organs's components include the nasal cavity, olfactory receptors, the nasal epithelium made of simple columnar epithelial cells, nasal passage, various glands, and muscles. So, the olfactory receptor cells and columnar epithelial cells in the nasal mucosa are the components of the olfactory organ nose.
Hence, the option 'a' and 'b' are correct.
