Detailed explanation-1: -Receptor, afferent neuron, integration center, efferent neuron, effector is the correct answer.
Detailed explanation-2: -The correct outline for the sequence of transmission of an electrical impulse through a neuron is dendrites, cell body, axon, axon terminal.
Detailed explanation-3: -So, the correct answer is ‘Receptors-Sensory neuron-Spinal cord-Motor neuron-Muscle’
Detailed explanation-4: -Thus the correct sequence is a sensory receptor, sensory neuron, interneuron, motor neuron and last effector.
Detailed explanation-5: -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).
