Which of the following statement is incorrect about skeletal muscle fibres?
Correct answer: B. They are 1-1 nm in diameter and surrounded by sarcolemma.
- A. They are multinucleated.
- B. They are 1-1 nm in diameter and surrounded by sarcolemma.
- C. They contain O2 storing molecules called myoglobin.
- D. Their cytoplasm contains the high concentration of carbohydrates .

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
