The repeated protein pattern of myofibril is called: (2014) Sarcomere Zyomere Sarcolemma Cross bridges 3. A sarcomere is the region myofibril between two successive: (2015) M-lines Z-lines I-bands T-tubules 4. The pigment which stores oxygen in muscles is: (2011) Haemoglobin Myoglobin Myosin Actinomyosin 5. Diameter of skeletal muscle fiber is: (2011) 2-50 µm 1-80 μm. 10-100 μm 30-90 μm 6. The length of the myofibril from one Z-band to the next is known as Sarcomere Sarcolemma Sarcoplasm Muscle fiber 7. The sarcolemma of muscle fiber folds inwards and forms a system of tubes which runs through the sarcoplasm called: (2015) Myofilament Sarcoplasmic reticulum Z-lines Transverse tubules 8. Muscle is made up of many cells which are referred to as: (2011 & 2013) Myofilaments Myofibrils Sarcolemma Muscle fiber 9. 10. The thick filaments in a myofibril of muscles are made of (2019) Haemoglobin Myoglobin Actin Myosin 11. Each muscle fibre is surrounded by a membrane called: (2012 & 2016) Sarcomere Capsule/ Myofilament Sarcolemma Twitch fibre/ Myosin filament 1 out of 1 Please fill in the comment box below.
