Question

Jaya's mother is preparing dosa in the kitchen she recognised the smell of dosa while she was planning in the verandra what process involved in this?

Answer 1

The sense of smell like sense of taste is part of the chemo sensory system, or the chemical senses. The ability to smell comes from specialized sensory cells, called olfactory sensory neurons, which are found in a small patch of tissue high inside the nose. These cells connect directly to the brain.

Each olfactory neuron has one odor receptor. Microscopic molecules released by substances around us, whether it's smell of dosa or pine trees in a forest, stimulate these receptors.

Once the neurons detect the molecules, they send messages to your brain, which identifies the smell. There are more smells in the environment than there are receptors, and any given molecule may stimulate a combination of receptors, creating a unique representation in the brain. These representations are registered by the brain as a particular smell.
