Question

Which of the following statements are true about fascicles?
I. They are held together by fascia
II. It contains a number of muscle fibres
III. Sarcolemma is the store house of calcium ions
IV. Sarcoplasm contains myofibrils

• A. II, IV
• B. I, III, IV
• C. I, II, IV
• D. I, IV

Answer 1

The correct option is C I, II, IV

Each skeletal muscle is made of muscle bundles or fascicles. Each fascicle contains many muscle fibres. Each muscle fibre has a plasma membrane called sarcolemma. The plasma membrane in muscle fibres i.e sarcolemma, has parallelly arranged filaments called myofibrils. Myofibrils are a characteristic feature of muscle fibres. The endoplasmic reticulum in muscle fibres is called sarcoplasmic reticulum is the store house of calcium ions.
