Brain, body and communication
Connect the central nervous system with pathways throughout the body.
The picture in words
- Central nervous system
- The brain and spinal cord.
- Peripheral nervous system
- Connections between the central system and the rest of the body.
- Sensory and motor signals
- Sensory information travels inward; motor signals travel toward muscles and other effectors.
Reading the illustration
The map summarizes two broad subdivisions. Sensory input and motor output travel through particular pathways within this larger system.
Try a question

Show the explanation
One shows information arriving from the body and surroundings. The other shows signals traveling from the central system toward a response.
