In the Nervous System , afferent neurons--otherwise known as Sensory or receptor Neuron s--carry Nerve Impulses from Receptor s or sense organs ''toward'' the Central Nervous System . This term is can also be used to describe relative connections between nervous structures. A touch or Pain ful Stimulus , for example, creates a Sensation in the brain only after information about the stimulus travels there via afferent nerve pathways. The structure of an afferent neuron contains a single long Dendrite and a short Axon ; the shape of the Cell Body of an afferent neuron is smooth and rounded. Just outside the Spinal Cord , thousands of afferent neuronal cell bodies are aggregated in a swelling in the Dorsal Root known as the Dorsal Root Ganglion An easy Mnemonic Device for remembering the relationship between ''afferent'' and ''efferent'' is that an ''afferent connection '''a'''rrives'' and an '''''e'''fferent connection '''e'''xits''.
