If we look at the efferent meaning, it refers to the neurons which carry away signals from the central nervous system towards the effector organs. This action of efferent neurons facilitates substance secretion from glands and muscle contraction. Efferent neurons only consist of one large axon, which makes a neuromuscular junction with the effector organs. Efferent neurons are divided further into different types, like general visceral efferent neurons, special visceral efferent neurons and somatic efferent neurons. There are further types of somatic neurons, alpha motor neurons and beta motor neurons. All these neurons help in carrying signals to the organs. For example, if a person is walking on the road and sees a bike coming towards him, he will suddenly jump on the side or make a side immediately. That is because efferent neurons immediately carry signals from the brain to the leg muscles to move out of the way.
