Home > Muscles#1 Muscles#1 Welcome to your Muscles#1 Name email 1. The pigment which stores oxygen in muscles is: (2011) Haemoglobin Myoglobin Myosin Actinomyosin 2. Diameter of skeletal muscle fiber is: (2011) 2-50 µm 1-80 μm. 10-100 μm 30-90 μm 3. Each muscle fibre is surrounded by a membrane called: (2012 & 2016) Sarcomere Capsule/ Myofilament Sarcolemma Twitch fibre/ Myosin filament 4. 5. A sarcomere is the region myofibril between two successive: (2015) M-lines Z-lines I-bands T-tubules 6. The length of the myofibril from one Z-band to the next is known as Sarcomere Sarcolemma Sarcoplasm Muscle fiber 7. Thin filaments of muscles contain chains of actin molecules. (2019) Four One Three Two 8. The thick filaments in a myofibril of muscles are made of (2019) Haemoglobin Myoglobin Actin Myosin 9. The repeated protein pattern of myofibril is called: (2014) Sarcomere Zyomere Sarcolemma Cross bridges 10. Muscle is made up of many cells which are referred to as: (2011 & 2013) Myofilaments Myofibrils Sarcolemma Muscle fiber 11. 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 1 out of 1 Please fill in the comment box below.
