From the left side to the right in sequence

1. sensory receptors→peripheral nervous system→(bipolar neurons;sensory/motor neuron) → CNS-interneurone→motor neuron →effectors.

Explanation:

The sequence of  actions represents the reflex pathways for the transmissions of action potential in living organisms. It is therefore called a reflex arc.

Its represent the transmission  of sensory impulses from  the peripheral nervous systems through the sensory neurons, to the CNS(brain and spinal cord)  as it enters at the  dorsal roots and the  transmission of  responses to the defectors, gland and muscles,  for effective responses.

The  brain and spinal cords process these information,the brain mediates the information,while the spinal cord serves as the neuronal conduits for the transmission of the impulses through  its ventral roots to the effectors via the motor neuron.
