|
|
fascicle, muscle organ, myofibril
|
|
|
fascicle, sarcomere, muscle organ
|

|
None of the above

Explanation:
Detailed explanation-1: -Based on the dimensions, the above-mentioned structures can be arranged in the following way from the largest to the smallest component: Muscle fiber → Myofibril → Sarcomere → Thin-filaments →Troponin.
Detailed explanation-2: -The smallest contractile unit of skeletal muscle is the muscle fiber or myofiber, which is a long cylindrical cell that contains many nuclei, mitochondria, and sarcomeres (Figure 1) [58].
Detailed explanation-3: -If we go from outside to inside, the correct muscle order would be epimysium, perimysium, fascicle, endomysium, muscle fibers, sarcolemma, myofibrils, and sarcomeres.
Detailed explanation-4: -muscle. fascicle. muscle fiber. myofibril. sarcomere. myofilament.
