The given question is not complete. The complete question is:
Number the steps from when a stimulus is received to when the body reacts.
The stimulus is received by sensory receptors.
Motor neurons cause muscles to contract so the body can react to the stimulus.
The brain processes the information through interneurons.
Interneurons transfer response information to motor neurons.
Sensory neurons carry stimulus information to the brain or spinal cord.
Answer:
The body of an organism like humans reacts towards each of the external stimuli of the environment like the smell of the food and even to the internal stimulus like hunger or pain. Thus, it can be considered that one is stimulated all the time and reacts towards the constituents found in the surroundings. The entire procedure of the organism reacting towards the stimuli are as follows:
1. The sensory receptors receive the stimulus.
2. The stimulus information is further carried to the spinal cord or the brain by the sensory neurons.
3. The processing of the information in the brain takes place with the assistance of interneurons.
4. After that the response information is mediated towards the motor neurons by the interneurons.
5. The motor neurons eventually result in the contraction of muscles showing that the body is reacting towards the stimulus.
