How does information get passed through your body and into the brain?

Neurons and dendrites, what they do is send impulses (surges) and send messages to your brain e.g "OOOOOOOooohhhh that smells nice!". If you feel something that is nice it tells your brain to move certain parts of your body. It controls digestion and the makes heart to pump blood and e.t.c this is why the brain is the most important thing for everyone. And gives you ideas such as songs and the synapse is the par of the brain service it's a tiny gap which sends the info into the brain and back out the neurons are the part that run through the nerves and through the spinal cord the dendrites the dendrites are the part which feed on information and help with memory and so on inside of a dendrite is a nucleus which keeps the dendrites in their spot.
