Detailed explanation-1: -Reflex arcs Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).
Detailed explanation-2: -Sensory neurons transmit information from sensory receptors to the central nervous system (CNS) Relay neurons (interneurons) transmit information within the CNS as part of the decision-making process. Motor neurons transmit information from the CNS to effectors (muscles or glands), in order to initiate a response.
Detailed explanation-3: -So the reflex arc consists of these five steps in order-sensor, sensory neuron, control center, motor neuron, and muscle. These five parts work as a relay team to take information up from the sensor to the spinal cord or brain and back down to the muscles.
Detailed explanation-4: -(d) Cerebrum—Diencephalon—Mid-brain—Cerebellum—Pons—Medulla oblongata.
