Let’s figure out what each arrow is pointing to in the nervous system diagram.
First, look at the top arrow — it’s pointing to the brain. The brain controls everything: thinking, moving, feeling, remembering. It’s like the boss of your body.
The second arrow points to the spinal cord — that long line going down the back inside the spine. It carries messages between the brain and the rest of the body. If you touch something hot, the signal goes up the spinal cord to the brain, and then the brain sends a message back to pull your hand away.
The third arrow (the one with two lines) is pointing to nerves in the arm. These are part of the peripheral nervous system — they carry signals from the brain and spinal cord to muscles and skin, so you can move and feel things.
So, putting it all together:
Final Answer:
- Top arrow: Brain – controls thoughts, memory, emotions, and body movements.
- Middle arrow: Spinal cord – carries messages between the brain and the body.
- Bottom arrows: Nerves – send signals to and from the brain/spinal cord to control movement and sensation in arms and legs.
