Question

Which of the following correctly identifies muscle
components in order from largest to smallest?
1. muscle fiber, myofibril, fasciculus
2. fasciculus, muscle fiber, myofibril
3. myofibril, fasciculus, muscle fiber
4. myofibril, fasciculus, muscle fiber​

Answer 1

Order of muscle components from largest to smallest is 2) fasciculus, muscle fiber, myofibril

Explanation:

Fasciculus or fascicle is the largest muscle which is present in the human skeleton. It is also known as the muscle fiber which is connected through tendon to the tissues.

Muscle fiber are composed of  myofibrils (long fibers that form muscles) and contain more than one nucleus. They are cylindrical in shape and posses several mitochondria to meet their energy needs.
