this entire process of response to a peripheral nervous stimulation yhat occurs involuntary means without conscious effort or thought and requires the involvement of a part of the central nervous system is called reflex action
the reflex pathway comprises at least one afferent neuron and one efferent neuron appropriately arranged in a series
the afferent neuron receive signals from a sensory organs and transmits the impulse via a dorsal nerve root into cns
the efferent neuron then carries signal from cns to effector
