Educational worksheet for labeling brain parts and matching functions.

Problem Analysis:

The task involves two parts:
1. Labeling the main parts of the brain in the provided illustration.
2. Matching the labeled parts of the brain with their respective functions.

#### Part A: Labeling the Brain Parts
The image shows a cross-section of the human brain with different regions colored differently. The task is to identify and label these regions using the correct terms.

#### Part B: Matching Functions
The second part requires matching the labeled brain parts (Cerebellum, Cerebrum, and Brain stem) with their corresponding functions as described in the text boxes.

Solution:

#### Step 1: Labeling the Brain Parts (Part A)
From the image, we can identify the following regions of the brain based on their typical appearance and location:

1. Top Left Region (Green Box): This region is the Cerebrum. It is the largest part of the brain and is responsible for voluntary movements, thinking, memory, and other higher functions.
2. Bottom Left Region (Green Box): This region is the Brain stem. It connects the brain to the spinal cord and controls basic life functions such as breathing, heart rate, and reflexes.
3. Right Region (Green Box): This region is the Cerebellum. It is involved in balance, coordination, and fine motor control.

So, the labels should be:
- Top Left: Cerebrum
- Bottom Left: Brain stem
- Right: Cerebellum

#### Step 2: Matching Functions (Part B)
Now, we match each labeled part of the brain with its function:

1. Cerebrum:
- Function: "It is the biggest part of the brain and controls voluntary movements."
- This matches the description of the cerebrum, which is the largest part of the brain and controls voluntary actions, thinking, and other higher functions.

2. Cerebellum:
- Function: "It is the part of the brain that controls your sense of balance, movement, and coordination."
- This matches the description of the cerebellum, which is responsible for balance, coordination, and fine motor skills.

3. Brain stem:
- Function: "It is in charge of those bodily functions that keep you alive or controls the involuntary movements."
- This matches the description of the brain stem, which controls essential life functions like breathing, heart rate, and reflexes.

Final Answer:

#### Part A: Labels
- Top Left: Cerebrum
- Bottom Left: Brain stem
- Right: Cerebellum

#### Part B: Matched Functions
1. Cerebrum: "It is the biggest part of the brain and controls voluntary movements."
2. Cerebellum: "It is the part of the brain that controls your sense of balance, movement, and coordination."
3. Brain stem: "It is in charge of those bodily functions that keep you alive or controls the involuntary movements."

Final Answer:
\[
\boxed{
\text{Cerebrum: Largest part, controls voluntary movements; Cerebellum: Controls balance, movement, and coordination; Brain stem: Controls basic life functions and involuntary movements.}
}
\]
