                                          Somatic nervous system



              Neural control                         of voluntary effectors: (skeletal muscles)

                                    single neuron having its cell body within the CNS and send axon to skeletal
               motor neuron
                                                                      muscles

           Effect of denervation          skeletal muscles enter a state of flaccid paralysis and atrophy.

              (Nerve damage)
                                    release of acetylcholine (ACh) from somatic motor neurons  ➔ stimulates
             neurotransmitter
                                                       the effector organ (skeletal muscles).
