Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
List the structures of a muscle from smallest to largest
A
myofibril, muscle fiber, fascicle, muscle
B
fascicle, muscle, myofibril, muscle fiber
C
fascicle, sarcomere, muscle, muscle fiber
D
myofibril, muscle, fascicle, sarcomere
Explanation: 

Detailed explanation-1: -From smallest to largest, the parts of a skeletal muscle are Myofilament, sarcomere, myofibril, muscle fiber, fascicle, muscle.

Detailed explanation-2: -In conclusion, the correct order of muscle structures is muscle, fascicles, fibers, myofibrils, and sarcomeres, from largest to smallest.

Detailed explanation-3: -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-4: -Answer and Explanation: Of all the answers, the largest structure is the fascicle. Fascicles are made up of muscle fibers and muscle fibers are made up of myofibrils. Myofibrils are made up of myofilaments which would make them the smallest structure in the list.

Detailed explanation-5: -muscle fiber. myofilament. myofibril. muscle fasciculus.
