Reflex Action-
The whole mechanism of reflex action occurs in such a fashion that there is no conscious control of the brain. Stimulation occurs through the peripheral nervous system and the response to this peripheral nerve stimulation is involuntary. In a reflex action, the spinal cord along with the brain stem is responsible for the reflex movements.
The whole process of reflex action involves some important components. They are receptor organs, sensory neurons, nerve center, associated neurons, motor neurons and effector neurons.
The receptor organs perceive the stimuli. They are situated on the sense organs. The afferent neurons or the sensory neurons carry the stimuli from receptors to the spinal cord. The ganglion of the spinal cord has the sensory neurons.
