Q.4. How do we detect the smell of an agarbatti (incense stick)?
The smell of agarbatti (incense stick) mixed in the air. It is detected by the olfactory receptor of the nose. The sensory nerves of the forebrain sent this information to the olfactory lobe and respond to the information signal.
Sensory information regarding smell is received by olfactory lobes of brains. As the air passes through the nasal chambers, the olfactory epithelial cells get stimulated and convey the information as electrical impulses to brain which have the power of interpretation
Our olfactory receptors located in nose receive the information of smell of an agarbatti and generates an electrical impulse. This impulse travels through sensory olfactory nerve to the forebrain. Forebrain has a separate area specilised for sensory impulse of smeel, where this information is interpreted and we detect the smell of an agarbatti
