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 carry signals from organs that respond to stimuli to the spinal cord and brain. The information that travels from one point to another does so via the central nervous system. The nerve cells that make up the sensory nerves are commonly known as sensory neurons. These particular neurons are one of three different types of neurons that are found within the body. The other two neurons are known as relay neurons and motor neurons. Relay neurons carry messages from on segment of the central nervous system to another while motor neurons carry signals from the central nervous system to effectors, which is an organ that has a particular effect when it is stimulated.
