Explanation The reflex arc is a particular type of neural circuit. It starts with a sensory neuron at a receptor and finish with a motor neuron at an effector. For example there is a pain receptor at the fingertip and it is carried to an effector (a skeletal muscle) of a sensory part. Somatic reflexes arc always engage the central nervous system. Even in the monosynaptic reflex, the somatic reflexes arc in which the sensory neuron directly triggers the motor neuron. That type of synapse is in the brain stem or spinal cord, so it has to occupy the CNS. The somatic reflex arc affects the muscles...
