Question

How is smell transmitted from the nasal cavity?

A) Through taste buds on the tongue
B) Through the Eustachian tube
C) Via the optic nerve
D) Olfactory nerve fibers transmit signals to the brain

Answer 1

Smell is transmitted from the nasal cavity through the olfactory nerve fibers. Olfactory receptors detect airborne odorant molecules and transmit signals to the olfactory bulb of the brain.

Step-by-step explanation:

Smell is transmitted from the nasal cavity through the olfactory nerve fibers.

Olfactory receptors, located in the olfactory epithelium, detect airborne odorant molecules.

These molecules bind to receptor proteins in olfactory sensory neurons, which then transmit signals to the olfactory bulb of the brain.
