Answer 1

Answer:

If you touch a hot stove, sensory receptors in your fingertip sense the dangerous heat and convert this stimulus into an electrical signal. This signal leaves your fingertip via nerve cells called SENSORY NEURONS (AFFERENT NEURONS). These nerves are part of an anatomical division of the nervous system called the PERIPHERAL NERVOUS SYSTEM. The signal travels along these nerves, and then to the spinal cord and brain. These two structures make up an anatomical division called the CENTRAL NERVOUS SYSTEM . Within this part of the nervous system, specialized nerves called INTERNEURONS integrate this information, formulate a response, and then communicate these instructions as nerve impulses to MOTOR NEURONS (EFFERENT NEURONS) . These neurons bring the message to the muscles in your arm to pull your hand away.

Explanation:

Receptor is the first component of the sensory pathway with the function to receive signal (it detects the change in environment, external or internal). Sensory neuron is responsible for the transport of signal from the receptor to the interneurons  which is then connected with the motor neuron.Motor neuron further sends the signal to the effector which produces the response (e.g. muscle contraction).
