Smell of a agarbatti is initially detected by olfactory receptors located in our nose. They then send impulses to the olfactory centre in the forebrain.
The olfactory receptors; present in the nostrils; pick the smell. They send signals to the brain. The brain interprets those signals and we detect the smell of an incense stick.
Smell of an agarbatti is detected by Nose, olfactory receptors present in the nose sends
electrical signal to the fore brain. Fore brain interprets this signal as the incense stick to be
detected as smell.
When the smell of the incense stick reaches to our nose then the olfactory receptors present in our nose detects it and send this information to the fore brain in the form of electrical signals.
Then, the fore brain interprets it by putting it together with the information received from other receptors and also with the information already stored in the brain.
At first, the smell of the incense stick reaches our nose, then the olfactory receptors present in our nose detect it. Then the receptors send this information to the forebrain in the form of electrical signals. Then the forebrain interprets this information as the smell of incense stick where it is already stored.
When the smell of the incense stick reaches to our nose then the olfactory receptors present in our nose detects it send this information in fore brain in the form of electrical signals. Fore brain interprets this information as the smell of incense stick where it is already stored.
The thinking part of our brain is the forebrain. It has separate areas that are specialized for hearing, smelling, sight, taste, touch, etc. The forebrain also has regions that collect information or impulses from the various receptors. When the smell of an incense stick reaches us, our forebrain detects it. Then, the forebrain interprets it by putting it together with the information received from other receptors and also with the information already stored in the brain.
