Sagot :
The correct order of the steps in recognizing a smell is:
1. Olfactory receptors detect vaporized odor molecules
2. Neurons are stimulated
3. Nerve impulse travels to the olfactory bulb in the brain
4. Signal forwarded to the cerebral cortex for interpretation
This neural code originates from sensory neurons in the nose. When an odorant molecule binds to a receptor it initiates an electrical signal that travels from sensory neurons to the olfactory bulb. The olfactory bulb is a structure at the base of the forebrain that relays signals to other brain regions for further processing.
Olfactory receptors are located in the olfactory epithelium. This is a specialized area of the nasal mucosa that covers part of the ethmoid bone in the upper nasal cavity. The reticular formation controls the level of consciousness, the cardiovascular system, and the respiratory system. The ascending sensory system passes through the brainstem on its way to the thalamus.
