Locomotion & Movement - NEET Previous Year Questions with Complete Solutions

No — this chapter is considered moderately easy relative to other Class 11 Biology chapters like Biomolecules or Breathing & Gas Exchange. Most questions are factual and directly drawn from NCERT. Students who read the chapter carefully, memorise the sarcomere diagram, and practise 5–6 years of PYQs can reliably score full marks from this chapter on exam day.

<p>The sliding filament theory and sarcomere structure is the highest-weightage topic. Questions on the A-band, I-band, H-zone, and Z-line — and which of these shorten or remain constant during contraction — appear almost every year. The second most tested area is joint classification, particularly the sub-types of synovial joints and their examples.</p>

<p>NEET typically includes 2 to 4 questions from Locomotion &amp; Movement every year. Based on NTA-released papers from 2016 to 2024, the average is approximately 2.7 questions per paper. This makes it a reliable scoring chapter because the question types repeat predictably across years, especially on sarcomere structure and joint classification.</p>

A sarcomere is the functional unit of a skeletal muscle, bounded by two Z-lines. It contains overlapping thick (myosin) and thin (actin) filaments arranged in bands. The sarcomere is central to NEET because it directly tests understanding of the sliding filament theory, and every component — A-band, I-band, H-zone, M-line — has appeared in at least one past NEET question between 2016 and 2024.

The most frequently tested disorders are Myasthenia Gravis (autoimmune; acetylcholine receptor blockade), Muscular Dystrophy (genetic degeneration), Tetany (low calcium causing spasms), Osteoporosis (low bone density), and Gout (uric acid crystal accumulation in joints). NEET questions typically ask for the cause or mechanism of the disorder, not just its name, so understanding the underlying biology is essential

<p>Start by reading NCERT Chapter 20 once fully. Then attempt the PYQs without looking at solutions. For every wrong answer, go back to the NCERT line or diagram that explains it — this builds source-level clarity. Finally, re-attempt all questions 10 days before the exam as a rapid revision test. Students following eSaral's structured NEET Biology programme — guided by expert faculty with Kota-level teaching experience — typically complete this loop in under 4 hours for this chapter.

PYQs cover 80–85% of what NEET will test from this chapter, because the concept pool is finite. However, you should supplement with at least one full mock chapter test to cover questions on bone counts (carpals, tarsals, vertebrae) and disorder mechanisms that appear less frequently but do appear in years when the paper is tougher.
