Question on: JAMB Biology - 2021
The correct sequence for the perception of smell in mammals is?
A
chemicals --> olfactory nerve endings --> brain
B
dissolved chemicals --> nasal sensory cells --> brain
C
chemicals --> mucus membrane sensory cells --> brain
D
dissolved chemicals --> sensory cells --> olfactory nerve --> brain
Ask EduPadi AI for a detailed answer
Correct Option: D
The correct sequence for the perception of smell in mammals is:
- Dissolved chemicals: Odor molecules must first be dissolved in the mucus lining of the nasal cavity.
- Sensory cells: These dissolved chemicals then stimulate the olfactory receptor cells (sensory cells) located in the olfactory epithelium.
- Olfactory nerve: The olfactory receptor cells transmit signals to the olfactory nerve.
- Brain: The olfactory nerve carries the signal to the olfactory bulb in the brain, where the smell is interpreted.
