Master Support & Movement in Animals for MDCAT 2025 with Detailed Notes

The Support & Movement chapter in MDCAT Biology is essential for understanding how the body maintains its shape and facilitates movement. This chapter covers the skeletal system, muscular system, and how they work together to enable movement and provide structural support. From bones to muscles, understanding how these systems function is crucial for MDCAT preparation, as it forms the foundation for other topics in physiology and anatomy.

In this blog post, we provide downloadable PDF notes on Support & Movement to help you efficiently prepare for MDCAT 2025.

Why Is Support & Movement Important for MDCAT?

High-Yield MDCAT Topic: The Support & Movement system is frequently tested in the MDCAT Biology section, with questions about bone structure, muscle types, and mechanisms of movement.
Critical for Medical Studies: Knowledge of the skeletal and muscular systems is vital for anyone pursuing careers in orthopedics, physiotherapy, and sports medicine.
Connects to Other Topics: Understanding support and movement is integral to studying human health, injuries, and diseases related to bones and muscles.

Key Concepts in Support & Movement for MDCAT

Skeletal System:
- Learn about the structure and function of bones, and how they provide support, protect internal organs, and store minerals.
- Study the different types of bones: long bones, short bones, flat bones, and irregular bones.
- Understand how bone marrow is involved in blood cell production (hematopoiesis).
- Study the bone structure at the cellular level: osteocytes, osteoblasts, and osteoclasts.
Types of Joints and Movements:
- Learn about the different types of joints: fibrous, cartilaginous, and synovial joints.
- Understand the range of movements these joints allow, including flexion, extension, rotation, and abduction.
- Study the synovial fluid and how it reduces friction in movable joints like the knee and elbow.
Muscular System:
- Study the three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle.
- Learn how skeletal muscles work in pairs (agonist and antagonist) to create movement.
- Explore the structure of skeletal muscles, focusing on muscle fibers, sarcomeres, and actin and myosin filaments that facilitate contraction.
- Understand the role of ATP in muscle contraction and the process of muscle fatigue.
Mechanism of Muscle Contraction:
- Study the sliding filament theory of muscle contraction, which explains how actin and myosin filaments slide past each other to shorten the muscle fiber.
- Learn about the role of calcium ions, troponin, and tropomyosin in the regulation of muscle contraction.
Locomotion:
- Understand how the musculoskeletal system works together to facilitate locomotion (walking, running, etc.).
- Study the role of tendons in connecting muscles to bones and facilitating movement.
Common Disorders and Diseases:
- Learn about common musculoskeletal disorders such as arthritis, osteoporosis, and muscular dystrophy.
- Understand how these diseases affect the skeletal and muscular systems and impact movement and support.
