Using motor and sensory neurons as examples, explain the difference between afferent and efferent.
What will be an ideal response?
An afferent axon brings information into a structure whereas an efferent axon carries information away from a structure. Sensory neurons detect sensory information (e.g., light, pressure) and convert that energy into neural impulses. That information is sent to the brain via afferent pathways. Motor neurons carry information from the brain and spinal cord to muscles and glands via efferent pathways.
