ankoles [38]

Answer:

The correct answer is -

1 - The stimulus is received by sensory receptors.

2 -  Sensory neurons carry stimulus information to the brain or spinal cord.

3 -  The brain processes the information through interneurons.

4 -  Interneurons transfer response information to motor neurons.

5 - Motor neurons cause muscles to contract so the body can react to the stimulus.

In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.

These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.
