Some of the Steps in Odor Perception

Question

1. An interneuron in the cerebrum is stimulated.
2. Acetylcholine attaches to an interneuron’s dendrites.
3. A wave of depolarization moves down the sensory neuron.
4. Sodium ions start to move rapidly into the sensory neuron.
The sequence of steps that occur in odour perception following the attachment of a
chemical to a sensory receptor is , , , and .

Answer 1

5. The sensory neuron sends signals to the olfactory bulb in the brain.
6. The olfactory bulb processes the signals and sends them to the olfactory cortex for further interpretation.
7. The brain interprets the signals and identifies the smell based on past experiences and memories.
