The brain communicates with the rest of your body by

The question says, how does the brain communicate with the rest of the body. The brain communicate with the other parts of the body by sending nerve impulse, which are form of electrical signal which travel throughout the body, carrying messages from the brain to the receptors and the cells of the body which respond appropriately to the signals.

The Central Nervous System is the "highway" in the body through which the brain transmits electrical pulses down the spinal chord to the nerves and organs. The brain sends and transmits these signals to control the functions of the body.Hope this helps. Let me know if you need additional help!
