Question

Number the steps from when a stimulus is received to when the body reacts.

Answer 1

Answer:

1. The stimulus is received by the 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.

Explanation:

In our relationship with the world, we are stimulated all the time and respond to the elements of the environment. With each external stimulus (such as the smell of food or the sound of a horn) and even internal stimulus (such as pain or hunger), the body reacts.

This reaction of the organism occurs in the central nervous system so instantaneously that our consciousness cannot identify all its stages, nor the thousands of stimuli that the body receives at all times. In short, we can state that the whole process of organism responses to stimuli occurs as follows:

1. The stimulus is received by the 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.

Answer 2

The following is the sequence of the steps from when the stimulus is received to the reaction of the body:  

1. The stimulus is received by the 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.
