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.
Sensory nerves deliver information about your surroundings to the brain. Motor nerves deliver signals from the brain to activate your muscles. Injuries or diseases that affect nerves and muscles can slow or halt the movement of these electrical signals. If you have pain, weakness or numbness in your back, neck or hands, measuring the speed and degree of electrical activity in your muscles and nerves can help your doctor make a proper diagnosis. This process is called electrodiagnostic testing.
