Let's solve this brain anatomy worksheet step by step.

Step 1: Identify the three major parts of the brain (A, B, C)

From the diagram and clues:

- A. Control Center → This refers to the brainstem, which regulates vital functions like breathing, heart rate, and sleep.
- B. Higher processes → This refers to the cerebrum, which is responsible for thinking, memory, language, and voluntary actions.
- C. Physical coordination → This refers to the cerebellum, which coordinates movement, balance, and motor control.

So:
- A: Brainstem
- B: Cerebrum
- C: Cerebellum

Step 2: Fill in the chart with names and functions

| NAME | FUNCTION |
|--------------|---------|
| A. Brainstem | Controls vital life functions such as breathing, heart rate, blood pressure, and reflexes. It acts as the "control center" for basic survival processes. |
| B. Cerebrum | Responsible for higher mental functions including thinking, reasoning, memory, emotions, speech, and voluntary movements. The largest part of the brain. |
| C. Cerebellum| Coordinates voluntary movements, balance, posture, and fine motor skills. Helps ensure smooth and accurate movements. |

Step 3: Match each activity to the correct brain part

Now let’s identify which part of the brain controls each listed activity.

1. Tasting a hamburger
- Taste is processed in the cerebrum (specifically the gustatory cortex).
→ Cerebrum

2. Artistic ability
- Creativity and artistic expression are managed by the cerebrum, especially the right hemisphere.
→ Cerebrum

3. Kicking a soccer ball
- Requires coordination and motor control → Cerebellum helps coordinate the movement.
→ Cerebellum

4. Rate of breathing
- Controlled automatically by the brainstem (medulla oblongata).
→ Brainstem

5. Tying your shoes
- This involves fine motor coordination and learned movements → Cerebellum helps with coordination, while cerebrum initiates the action. But the key coordinator is the cerebellum.
→ Cerebellum

✔ Final Answers:

#### Diagram Labels:
- A: Brainstem
- B: Cerebrum
- C: Cerebellum

#### Chart:
| NAME | FUNCTION |
|--------------|---------|
| A. Brainstem | Controls vital functions like breathing, heart rate, and blood pressure; serves as the body’s control center. |
| B. Cerebrum | Responsible for higher cognitive functions such as thinking, memory, language, and voluntary movements. |
| C. Cerebellum| Coordinates muscle movements, balance, and fine motor skills. |

#### Activity Matching:
1. Tasting a hamburger → Cerebrum
2. Artistic ability → Cerebrum
3. Kicking a soccer ball → Cerebellum
4. Rate of breathing → Brainstem
5. Tying your shoes → Cerebellum
