Voluntary Action
(Recall: voluntary action is under conscious control) (it is a deliberate action)
Example: you decide to raise your hand to answer a question in class. → nerve impulses are produced in the brain. nerve impulses are transmitted by a relay neurone in the CNS from the brain, down the spinal chord. In the spinal chord, nerve impulses are transmitted to the motor neurone, which transmits the nerve impulses to the effector muscles in your arm. → muscle contracts and your hand is raised.
