Q1. What are the functions of the skeletal system?

Background

Topic: Functions of the Skeletal System

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

Key Terms:

  • Protection

  • Mineral Storage

  • Acid-Base Homeostasis

  • Blood Cell Formation

  • Fat Storage

  • Movement

  • Support

Step-by-Step Guidance

  1. Start by listing the main functions of the skeletal system. Think about how bones interact with other body systems.

  2. For each function, briefly describe what it means. For example, how does the skeleton provide protection?

  3. Consider examples for each function, such as which bones protect vital organs or how bones store minerals.

  4. Reflect on how the skeletal system contributes to movement and support, and how it is involved in blood cell and fat storage.

Q4. Describe the extracellular matrix of bone.

Background

Topic: Bone Extracellular Matrix

This question focuses on the composition and function of the bone's extracellular matrix, which is crucial for bone strength and flexibility.

Key Terms:

  • Organic Matrix (Osteoid)

Step-by-Step Guidance

  1. Identify the two main components of the bone matrix: inorganic and organic.

  2. Describe the composition of the inorganic matrix (e.g., hydroxyapatite crystals).

  3. Describe the composition of the organic matrix (e.g., collagen fibers).

  4. Explain how each component contributes to bone properties (strength, flexibility).

Q6. Compare and contrast the anatomical features of compact bone and spongy bone, including where each type can be found.

Background

Topic: Bone Structure

This question examines your understanding of the structural differences between compact and spongy bone and their locations.

Key Terms:

  • Compact Bone (Osteon, Lamellae, Central Canal)

  • Spongy Bone (Trabeculae)

Step-by-Step Guidance

  1. Define compact bone and spongy bone.

  2. Describe the structural units of each (e.g., osteons for compact bone, trabeculae for spongy bone).

  3. Explain the functional differences between the two types.

  4. Identify where each type is typically found in the skeleton.
