1 When you have one of those infected zits and you try to pop it but the pain is just too much to bear; it is sensory (afferent) neurons that are telling your brain about the pain.  Motor (sometimes called Efferent) Neurons: Motor (Efferent) neurons take information from the brain and send in out to the rest of the body. If you have your heart set on popping that zit, you use motor (efferent) neurons to move your fingers into the proper pinching to pop position.
The motor nervous system receives processed information from the CNS and sends the signals through efferent motor fibers (nerves). The motor fibers send the signal to voluntary skeletal muscles. In contrast, the autonomic nervous system (ANS) controls the glands and the smooth involuntary muscles.
