UNIT 09 : SUPPORT & MOVEMENT
Support and Movement is one of the many chapters feeding into the 45% Biology allocation of your 180-question MDCAT paper, with Biology contributing 81 MCQs overall.
What this chapter covers:
- Human skeleton
- Describe cartilage, muscle and bone
- Explain the main characteristics of cartilage and bone along with functions
- Muscles
- Compare characteristics of smooth muscles, cardiac muscles and skeletal muscles
- Skeletal muscles
- Explain the ultra-structure of skeletal muscles
- Muscle contraction
- Describe in brief the process of skeletal muscle contraction
- Joints
- Classify joints
- Arthritis
- Define arthritis
This chapter is largely conceptual and structural rather than calculation-based, built around naming, locating, and comparing anatomical structures, cell types, joint categories, and stepwise physiological mechanisms like the sliding filament model. Given the density of named structures and processes packed into a single chapter, it spans the full difficulty range described in the PMDC guideline, from straightforward recall of bone or muscle terminology to moderate comparison-based questions to more difficult mechanism-sequencing questions on contraction and fracture repair.
Why this practice set helps:
- Covers every subtopic the PMDC curriculum identifies, plus the supporting concepts textbooks present alongside them
- Every question includes a full explanation of why the correct answer is right and why each other option is wrong
- Built to help you learn faster than passive reading, with nothing the exam may draw from left untouched
Work through this set attentively, and you build both the precise structural memorization and the step-by-step mechanistic clarity this chapter demands.
