Nervous System Activity Worksheets - Free Printable

The image you've uploaded is a worksheet titled "The Nervous System", which asks students to locate and describe the function of three key components: the brain, spinal cord, and nerves. The diagram shows a simplified human figure with outlines of the brain, spinal cord, and nerves extending throughout the body.

Here's how to solve this task:

🔍 Step 1: Identify the Structures

On the diagram:

- Brain: Located in the head (inside the skull), shown as a large organ at the top of the figure.
- Spinal Cord: Runs down the center of the back, inside the spine (vertebral column), connecting the brain to the rest of the body.
- Nerves: Represented as lines branching out from the spinal cord to arms, legs, and other parts of the body.

🧠 Step 2: Describe the Function of Each Part

#### 1. Brain
- Location: Inside the skull, at the top of the spinal cord.
- Function: The brain is the control center of the nervous system. It processes information from the senses, controls thoughts, memory, emotions, and coordinates voluntary and involuntary actions (like breathing and heartbeat).

#### 2. Spinal Cord
- Location: Runs from the base of the brain down through the vertebral column (spine).
- Function: Acts as a communication pathway between the brain and the rest of the body. It transmits messages (signals) from the brain to muscles and organs, and sends sensory information (like pain or touch) from the body back to the brain. It also controls reflexes (e.g., pulling your hand away from something hot).

#### 3. Nerves
- Location: Branching out from the spinal cord and brain to all parts of the body.
- Function: Nerves are like cables that carry electrical signals (nerve impulses) between the brain/spinal cord and the rest of the body. They transmit sensory information (from skin, muscles, etc.) to the CNS and motor commands from the CNS to muscles and glands.

✔ Final Answer (to write on the worksheet):

> Brain: Located in the skull; controls thought, memory, movement, and body functions.
> Spinal Cord: Runs from the brain down the spine; carries messages between the brain and body and controls reflexes.
> Nerves: Extend from the brain and spinal cord to all body parts; transmit signals for sensation and movement.

💡 Tips for Students:

- Use arrows or labels on the diagram to point to each structure.
- Color-code them if allowed (e.g., brain = blue, spinal cord = red, nerves = green).
- Write short, clear sentences describing each function.
