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

Part 1: Identify the three major parts of the brain

We are given a diagram of the human brain with three labeled sections:

- A. Labeled as "Control Center"
- B. Labeled as "Higher processes"
- C. Labeled as "Physical coordination"

Based on standard brain anatomy and the descriptions:

#### A. Control Center
This refers to the brainstem, which includes structures like the medulla oblongata, pons, and midbrain. It regulates vital autonomic functions such as breathing, heart rate, and blood pressure.

✔ Answer: Brainstem

#### B. Higher processes
This refers to the cerebrum, specifically the cerebral cortex. The cerebrum is responsible for higher cognitive functions such as thinking, memory, reasoning, problem-solving, and voluntary movement.

✔ Answer: Cerebrum

#### C. Physical coordination
This refers to the cerebellum, located at the back of the brain below the cerebrum. It coordinates voluntary movements, balance, and fine motor control.

✔ Answer: Cerebellum

Fill in the chart:

| NAME | FUNCTION |
|----------------|----------|
| A. Brainstem | Controls vital life functions such as breathing, heart rate, and blood pressure. Acts as the body’s control center for automatic processes. |
| B. Cerebrum | Responsible for higher mental functions including thought, memory, language, perception, and voluntary actions. |
| C. Cerebellum | Coordinates voluntary movements, balance, and muscle tone; ensures smooth and precise motor activity. |

Part 2: Match activities to brain regions

Now, identify which part of the brain controls each listed activity.

#### 1. Tasting a hamburger
- Taste is processed in the cerebrum, specifically in the parietal lobe (gustatory cortex).
- The cerebrum interprets sensory input from taste buds.
✔ Answer: Cerebrum

#### 2. Artistic ability
- Artistic skills involve creativity, visual processing, and motor coordination.
- These are primarily controlled by the cerebrum, especially the right hemisphere (which is associated with creativity and spatial awareness).
✔ Answer: Cerebrum

#### 3. Kicking a soccer ball
- This involves coordinated voluntary movement.
- The cerebellum helps coordinate the muscles involved in the motion, while the cerebrum plans the movement.
- However, coordination is the key function here.
✔ Answer: Cerebellum

#### 4. Rate of breathing
- Breathing is an involuntary process regulated by the medulla oblongata, which is part of the brainstem.
✔ Answer: Brainstem

#### 5. Tying your shoes
- This requires fine motor skills and coordination.
- The cerebellum coordinates the precise movements, while the cerebrum initiates the action.
- But again, coordination is key.
✔ Answer: Cerebellum

✔ Final Answers:

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

#### Chart – Functions:
| NAME | FUNCTION |
|----------------|----------|
| A. Brainstem | Regulates vital functions like breathing, heart rate, and blood pressure. |
| B. Cerebrum | Controls higher mental processes such as thinking, memory, language, and voluntary movement. |
| C. Cerebellum | Coordinates movement, balance, and fine motor control. |

#### Activity Matching:
| NAME | FUNCTION |
|--------------------------|----------------|
| 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 |

📌 Summary:

This worksheet teaches how different parts of the brain work together:
- The cerebrum handles thinking and senses.
- The cerebellum manages coordination.
- The brainstem controls automatic survival functions.

You now have a complete understanding of the brain’s major regions and their roles!
