Q6.01. List five major functions of the skeletal system.

Background

Topic: Skeletal System Functions

This question tests your understanding of the essential roles that the skeletal system plays in the human body, beyond just providing structure.

Key Terms:

• Support

• Protection

• Movement/Leverage

• Mineral Storage and Release

• Blood Cell Formation (Hematopoiesis)

• Fat Storage (in yellow marrow)

Step-by-Step Guidance

1. Think about how bones provide a framework for the body and support soft tissues.

2. Consider how certain bones protect vital organs (e.g., skull, rib cage).

3. Recall how muscles attach to bones and how this enables movement.

4. Remember that bones store minerals, especially calcium and phosphate, and can release them into the bloodstream as needed.

5. Think about where blood cells are produced in the body and which part of the bone is responsible for this function.

Q6.02. Classify bones as long, short, flat, irregular, or sesamoid. Give one example of each.

Background

Topic: Bone Classification

This question assesses your ability to recognize the different shapes of bones and provide examples for each type.

Key Terms:

• Long bones

• Short bones

• Flat bones

• Irregular bones

• Sesamoid bones

Step-by-Step Guidance

1. Recall the defining features of each bone type (e.g., long bones are longer than they are wide).

2. Think of a bone in the body that fits each description (e.g., femur for long bone).

3. For sesamoid bones, consider bones that form within tendons.

4. Write down one example for each category.

Q6.03. Distinguish red bone marrow from yellow bone marrow.

Background

Topic: Bone Marrow Types

This question tests your knowledge of the two main types of bone marrow and their functions in the body.

Key Terms:

• Red bone marrow: hematopoietic tissue

• Yellow bone marrow: adipose tissue

Step-by-Step Guidance

1. Recall which type of marrow is responsible for producing blood cells.

2. Think about the main component of yellow marrow and its function.

3. Consider where each type of marrow is typically found in the body (e.g., red marrow in flat bones and epiphyses, yellow in diaphysis of long bones).

Q6.04. What is the difference between compact bone and spongy bone?

Background

Topic: Bone Structure

This question examines your understanding of the two main types of osseous tissue and their structural and functional differences.

Key Terms:

• Compact bone (cortical bone)

• Spongy bone (cancellous bone)

• Osteons

• Trabeculae

Step-by-Step Guidance

1. Recall the location of compact bone in a typical bone (outer layer).

2. Think about the microscopic structure of compact bone (presence of osteons).

3. Consider the structure and location of spongy bone (trabeculae, marrow spaces, no osteons).

4. Compare the density and function of each type.
