Your nervous system sends messages from the body to the brain. Different kinds of Neurons are used to send each message, to allow your brain to know what is going on in your environment. The things that cause a reaction are called Stimuli. Messages are sent along nerve cells, or Neurons.
For instance, if you prick your finger on a pin, a sensor in your skin called a Receptor sends a message of pain through a Sensory Neuron, to a Relay neuron in your Central Nervous System (which is your brain and spinal cord). The message is then sent through the CNS, to the brain, so your brain can decide how to react to the pain. The message is THEN sent through a motor neuron, which causes your muscles to move to react to the message. (Something that reacts to a message from a neuron is called an Effector- because it causes an effect.) In this case, the message from the motor neuron to the effector- your muscle- would make you pull your hand back, to get it away from the pin.
In short: A change in your environment, like pain, is picked up by a Receptor.
The message picked up by the Receptor is sent through a Sensory Neuron.
The message is then sent through the Central Nervous System by Relay Neuron.
Once the brain has decided what to do, it sends a message to the Motor Neuron.
The Motor Neuron triggers an Effector (a muscle, or some chemical secretion) to react to the change.
It may not be completely correct, but I'm 90% sure that's at least a rough, simple version.

Part of your ear sends the message to your brain that you've heard a sound?
The cochlea
Which part of the human body sends signals to help you move breath and eat etc.?
The brain.....
Which part of the ear sends a message to the brain that is recognized as sound?
The simple answer: In the inner ear the cochlea (the roundish wound up thing that looks a little like a snail shell to me), picks up vibrations from the eardrum (AKA Tympanic membrane) which are then converted to nerve impulses, which are received by the brain as sound.
What body part is the eye connected to?
By the optic nerve, which is connected to the brain. The optic nerves takes nerve signals from the retina and sends it to the brain.
How does the peripheral nervous system work?
An example of the peripheral nervous system that you can control is instructions that are being carried from your brain to your limbs. It sends all of the information from your senses back to your brain.
Part of your ear sends the message to your brain that you've heard a sound?
The cochlea
Which part of your ear sends the message to your brain that you've heard something?
Auditory Nerve
What type of communication is fastest in body?
that would be the message-sending nervous system. it sends messages from your brain through your body telling it to perform certain tasks, like a reflex or movement of any part of your body.
What part of a neuron sends a message?
Axon sends the message. Dendrite receives it.
What part of the skin sends the message to the brain?
There are receptors in the dermal part of the skin that sends various types of information to the brain; hot, cold, light touch, pressure (deep touch) and pain.
What is the brain's relationship with other organs in your body?
all of your organs are connected to your brain. for example when you touch something hot your brain sends impulses to the body part to move.
What links the brain to the rest of your body and sends messages back and forth?
your spine and skeletal system sends messages that you are in pain when your bones break. your eyes send messages about what you are seeing your fingers, arms, and every other part of your body responds to what you are touching and also sends messages to your brain to stimulate responses in whether it is a good or bad pain.
Which part of the human body sends signals to help you move breath and eat etc.?
The brain.....
What part of the brain control the muscle?
Many parts of the brain control your muscles. There is a part of the brain called the Central Nerve System or CNS located towards the center of the brain. This are controls your nerves and movement. Everytime you want to move a body part, your brain sends a message lightning speed to your nerves and that is how you move. Without the Central Nerve System, you would be paralized and unable to move.
What is the part of nerve cell transmit messagefrom the brain to the different part of the body?
Motor neurone send message from the brain to the affector
What action should muscles do to enable the bones to perform or move?
Bones do not move. Nerves are what causes muscles to move. Nerves are connected to the brain. When you attempt to move any body part, your brain instantaneously sends a message to the specific nerves needed to make that body part move. Which makes the muscles flex resulting in movement.
