The Nervous System worksheet featuring a human body outline and space for labeling key components.

Explanation:
This worksheet asks you to label parts of the nervous system using a diagram of the human body and a word bank. Since no word bank is provided in the prompt, and the image (which we’re not describing) likely contains standard terms like *brain*, *spinal cord*, *nerves*, etc., the correct labeling would match common anatomy:

- The large structure inside the skull → Brain
- The long bundle running down the center of the spine → Spinal cord
- The lines extending from the spinal cord to limbs and organs → Nerves (or *peripheral nerves*)
- The brain + spinal cord together are the Central Nervous System (CNS)
- The rest (nerves outside CNS) form the Peripheral Nervous System (PNS)

However, since the worksheet shows three blank boxes next to the diagram (likely for 3 main parts), and a labeled “Word Bank” area (but no words given here), the most typical answer expected for a basic level is:

1. Brain
2. Spinal cord
3. Nerves

These are the three primary structural components students are usually asked to identify at this level.

Let’s double-check:
- The brain controls thinking, breathing, heartbeat, etc.
- The spinal cord carries signals between brain and body.
- Nerves carry messages to and from muscles, skin, organs.

Yes — those are the core parts to label.

Final Answer:
Brain, Spinal cord, Nerves
