Detailed explanation-1: -The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.
Detailed explanation-2: -The reflex arc consists of the following parts namely-a specific receptor, an afferent nerve fiber, an association neuron, an efferent motor neuron, and an effector organ. The neurons of a specific receptor receive a stimulus and set up a sensory impulse.
Detailed explanation-3: -Thus the correct sequence is a sensory receptor, sensory neuron, interneuron, motor neuron and last effector.
Detailed explanation-4: -Receptor. Sensory neurons. Association neurons. Motor neurons. Effector.
