Observe the given steps related to the experience of taste and arrange them properly. Impulses reach the brain through the nerves. The taste detecting chemoreceptors are stimulated. The substances reach the taste buds through saliva. Substances responsible for taste dissolves in saliva. Forms the experience of taste. Impulses form in the chemical receptors.

Taste can be characterised as a physiological process by which we can know the nature of the food. At first, we intake the food and the foods are broken into pieces by teeth and lubricated by saliva. The tongue facilitates the process of mixing food with saliva. The food particles are sensed by the taste buds. Then the chemoreceptors get stimulated and the impulses for the taste are carried by the glossopharyngeal nerve. This nerve carries the impulse to the brain. After the processing of impulses, the individual can experience the taste of the food. The steps are arranged and given below: Substances responsible for taste dissolve in saliva. The substance reaches the taste buds through saliva. The taste detecting chemoreceptors are stimulated. Impulses form in the chemical receptors. Impulses reach the brain through the nerves. Forms the experience of taste.
