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:

#### A. Control Center → Brainstem
- The brainstem is located at the base of the brain and connects the brain to the spinal cord.
- It controls vital automatic functions like breathing, heart rate, blood pressure, and sleep cycles.
- It acts as the "control center" for basic life-sustaining functions.

#### B. Higher processes → Cerebrum
- The cerebrum is the largest part of the brain, located in the upper portion.
- It is responsible for higher cognitive functions such as thinking, memory, problem-solving, language, and voluntary movement.
- It’s divided into two hemispheres and contains the cerebral cortex.

#### C. Physical coordination → Cerebellum
- The cerebellum is located at the back of the brain, below the cerebrum.
- Its main function is to coordinate voluntary movements, balance, and motor control.
- It ensures smooth and precise movements.

✔ Completed Chart (Top Section):

| NAME | FUNCTION |
|--------------|---------|
| A. Brainstem | Controls vital functions like breathing, heart rate, and consciousness. Acts as the body’s control center. |
| B. Cerebrum | Responsible for higher mental functions such as thinking, memory, learning, and voluntary movement. |
| C. Cerebellum| Coordinates muscle movements, balance, and fine motor skills. |

Part 2: Match activities to brain regions

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

1. Tasting a hamburger
- Function: Taste perception
- Brain Region: Cerebrum (specifically, the parietal lobe, which processes sensory information including taste)
- Answer: Cerebrum

2. Artistic ability
- Function: Creativity, visual processing, imagination
- Brain Region: Cerebrum (especially the right hemisphere, involved in creativity and spatial awareness)
- Answer: Cerebrum

3. Kicking a soccer ball
- Function: Coordinated voluntary movement
- Brain Region: Cerebellum (coordinates movement), and Cerebrum (plans the movement)
- However, the primary coordinator of physical coordination is the cerebellum.
- Answer: Cerebellum

4. Rate of breathing
- Function: Automatic regulation of respiration
- Brain Region: Brainstem (specifically the medulla oblongata)
- Answer: Brainstem

5. Tying your shoes
- Function: Fine motor coordination and balance
- Brain Region: Cerebellum (for coordination) and cerebrum (for planning)
- But the key organ for physical coordination is the cerebellum
- Answer: Cerebellum

✔ Final Answers for Bottom Section:

| 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 of Key Brain Parts:

| Brain Part | Location & Function |
|---------------|---------------------|
| Cerebrum | Largest part; higher thinking, memory, voluntary actions |
| Cerebellum| Back of brain; coordinates movement, balance |
| Brainstem | Base of brain; regulates breathing, heartbeat, sleep |
