Psych 11Nervous System Overview
... A touch or painful stimulus, for example, creates a sensation in the brain only after information about the stimulus travels there via afferent nerve pathways. Afferent neurons have a single long dendrite and a short axon. The dendrite is structurally and functionally similar to an axon, and is ...
