The diagram given below represents the history of a striped muscle. Label the parts A, B, C, D, E and F.
- A A-Sarcoplasm, B-Nucleus, C-Sarcolemma, D-Myofibril, E-Dark band, F-Light band
- B A-Sarcoplasm, B-Light band, C-Myofibril, D-Sarcolemma, E-Nucleus, F-Dark band
- C A-Light band, B-Sarcoplasm, C-Myofibril, D-Sarcolemma, E-Nucleus, F-Dark band
- D A-Sarcolemma, B-Nucleus, C-Dark band, D-Light band, E-Sarcoplasm, F-Myofibril
Answer & Solution
Correct Answer
(C) A-Light band, B-Sarcoplasm, C-Myofibril, D-Sarcolemma, E-Nucleus, F-Dark band
Step-by-step Solution
Detailed explanation
(C) A-Light band, B-Sarcoplasm, C-Myofibril, D-Sarcolemma, E-Nucleus, F-Dark band,
In striated muscle, A (light band) and F (Dark band) represent alternating regions of myo-filament arrange-ment, with C (Myofibril) being the contractile unit within the muscle fiber. B (Sarcoplasm) is the cytoplasm of the muscle cell, and D (Sarcolemma) is its plasma membrane. E (Nucleus) is located at the periphery of the muscle fiber.
