You know that you shouldn't eat the cookies on the counter because you are trying to lose weight, but you decide to eat one anyway, so you reach out to pick one up.
Explanation / Answer
The basic pathway which describes the functioning of nerve impulse can be summarized as follows -
The first event is stimulus which is something that our sensory receptors detect - they can range from sight,sound, taste, visual sensation etc. After stimulus is detected, the sensory receptors recognise the stimulus. These receptors are present all over body and some types of receptors are located in a specific area e.g. taste receptor on tongue. The next stage involve carrying of the information by the sensory neurons to the CNS which is received and processed by the brain and further transmitted by relay neurons to the effector.
