The brain can get signals, add them up, and signal back for action in a split second. Different parts of the brain do different things.
The medulla, at the top of the signal cord, controls nerves that are in charge of certain muscles and glands. The medulla keeps your heart beating, your lungs taking in air and your stomach digesting food.
The cerebellum controls body movement and balance. The cerebellum is where is where thinking, learning, remembering, deciding and awareness take place. The sensation of seeing, smelling, tasting and touching are centred here. So are the body feelings.
The so far have learnt that the messages travel through the nervous system -to and from the brain- are weak electrical charges. The billions of nerve cells in the body form a huge network that leads to the spine. Along the way, nerves from different parts of the body come together in thick bundles. A thick cable of nerves runs up the hollow of the spine to brain. One set of the nerves in the cable carries messages from senses to brain. Another set carries messages from the brain to the muscles and glands. The brain sorts out the signals and makes the right connections.

Nerves do not send blood, rather it is arteries and veins that transports blood throughout the body.
Big brain of course because brains send down quick messages to the nerves in the body and then you walk upright
Putting your hand in water can stimulate the nerves in your body, which can send a signal to your brain that it's time to pee. This is because the nerves that control your bladder and the nerves in your hand are connected in the spinal cord.
To send electrical impulses from the body to the brain, and vice versa.
to send the message to all parts of the body.

Nerves Send Messages To The Different Body Parts
The peripheral nervous system contains all the nerves in the body that lie outside of the spinal cord and brain.They communicate with the central nervous system to make sure our body parts, such as our fingers, can send signals to the central nervous system for processing in our brains.
Nerves tell glands when to release chemicals. Nerves send messages to glands. Apex- Nerves instruct glands to send out hormones.
to send signals through the body when you touch something hot
Afferent nerves are those that send impulses from the PNS to the CNS. Efferent nerves send impulses from the CNS to the PNS. So the first goes toward the Central Nervous System and the second goes away from it.
So that nerves can send a signal to the bundle instead of each individual fiber.
