Do you know what an involuntary action is? Well it is when you don’t chose to do something, like when you blink, breath or even sneeze. Now do you know what a voluntary action is? It is just like an involuntary action, but you choose to do it, like picking up something, sitting down, or turning on the television. Say I want to take out the trash. First, I think about it in my brain. The message travels from nerve to nerve to the spinal cord and to the hands to pick up the trash bag. A message is also sent to the legs to walk to the trash can.
In the nervous system there are a lot of parts. There is something called
the
Do you know what the spinal cord does? The spinal cord is a very important
part of the nervous system. The spinal cord is a highway where messages are
constantly traveling. I am Nick the "Nerve" with "The Nervous System Report,"

Hi
my name is Nick the nerve and I’m here to tell you about the nervous system.
If somebody touches something hot their reflex sends a message to nerve to nerve
until it gets to the spinal cord. The spinal cord sends the message back to
the hand and at the same time the message travels up to the brain. The spinal
cord send a message to your muscles to move your hand. The brain lets you
know you just touched something hot so we moved your hand.
Cerebrum.
The Cerebrum is the largest part of your brain and is very wrinkly It controls thought,
voluntary movement, memory, and learning. The Cerebellum is below the
cerebrum and it controls muscles, balance, and posture. Below the
Cerebellum is he brain stem
which controls breathing, heart beat and reflexes.
