Which one of the following statements is incorrect about muscles in human body?
Detailed Explanation:
❌ Statement 1 – Incorrect: Muscles can only pull the bone, not push; they work by contraction (pulling) and cannot actively push.
✅ Statement 2 – Correct: Muscles work in antagonistic pairs (e.g., biceps and triceps) – when one contracts (pulls), the other relaxes.
✅ Statement 3 – Correct: During contraction, muscle fibers become shorter, stiffer, and thicker as actin and myosin filaments slide over each other.
