Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.
Explanation:
The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain. The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.
