What part of the body sends a message to the brain?
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.
How does the brain perceive the intensity of a stimulus?
There are a number of different ways that the brain perceives stimuli. If a person is hurt, the brain sends a reaction to the body. If something good happens, the brain sends good reactions to the body.
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 are the electrical signals called which are sent to our brain?
There are a few things that pass message from the ear to the brain. The most likely answer is the ear canal.
How does the brain send messages to the rest of the body?
if i am correct the brain sends messages to the rest of the body by sending pulses down your spine where it connects to the brain. most of the major parts in your body are connected somehow to the spine. the messages break off from the spine and get sent to the rest of the body.
When you are walking the brain sends messages to the skeletal muscles in the legs by way of?
All the brain's messages are sent through the nervous system.
What your brain communicates to your body depends largely on what messages your body sent first to your brain?
true
How do messages get from a certain point in your body to your brain?
the brain stem also sorts though the millions of messages that the brain and the rest of the body sent back and forth.
Which body system receives environmental messages and sends them to the brain?
Both the nervous system and the endocrine system send messages to the brain
Describe how messages are sent in the brain?
The neurons in the body take the messages and they go to the brain and back to the body. if we didn't have neurons we woudn't know what we felt or other 5 senses, about something..
How do the neurons sent messages to the brain?
electrical impulses
Why is a person who breaks his backbone often paralyzed in the lower part of his body?
the backbone actually consists of spinal cord.spinal cord carries the nerves to brain the message for movement of lower part or any part of the body is sent by brain through spinal cord.so ,if backbone breaks the person will become paralysed.

Where does the nervous system start?
The nervous system starts in the brain, which is the main control center of the body. From the brain, messages are sent through the spinal cord, which acts as a pathway to relay information between the brain and the rest of the body.
Do instant messages sent to cellphones charge the carrier of the phone?
Nope. Not unless you, yourself, sends it.
What is the sequence of events in a reflex?
The answer to this question is that first something will happen. For example when you go the doctor, he/she will tap your knee with a little mallet to test your reflexes. Then a message is sent to your brain from your knee telling the brain that the knee has been tapped. Then the brain sends a message back to the knee ''telling'' it to jerk the leg forward. Basically the events of a reflex is sending messages back and forth throughout the body.
