Nerve tissue
the brain stem also sorts though the millions of messages that the brain and the rest of the body sent back and forth.
The cells that are able to pass messages back and fourth are called neurons. These neurons are found in the brain.
Lymphatic system.
Nervous tissue sends messages from the brain to the rest of the body. It consists of neurons that transmit electrical signals to communicate information throughout the body.
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.
They were used to communicate messages back and forth between the home military and the front line military.
All the nerves in your body are connected to your spinal nerves which then send messages from different areas in your body up through your central nervous system to your brain. Ex: When you walk your nerves in your feet and legs send a message up into your spine to the brain. So the question isn't really carrying messages toward or away its that it sends messages back and forth through your spine actually.
your spine!!
Neurons
Nerves send information to your brain such has if something is hot or cold. And your brain also sends messages through your nerves such has lift the arm, left leg forward, right leg up, so on and so forth
Neurons are the cells responsible for sending and receiving messages in the nervous system. They can pass messages back and forth by transmitting electrical signals along their length and releasing chemical messengers called neurotransmitters at the synapses to communicate with other neurons or target cells.
