6. Reflex action is an action by

which a measuge is short circült ed in the spinal cord and thus need not involve the brain but in voluntary action, the stimulus is first analysed in the forėtrain before a response is carried out: Thus reflex actions are unconsci- qus und tunter Wiille voluntury. actions are conscious actions and.
