Put the following structures in order from superficial to deep. 1. Muscle fiber 2. Perimysium 3. Myofibril 4. Fascicle 5. Endomysium 6. Epimysium

6. Epimysium is a tough layer of connective tissue that anchors muscle tissue to tendons and protects muscles.

2. Perimysium envelops more muscle (10-100) fibers collectively into bundles-fascicles.

4. Fascicles are multiple bundles found within the epimysium.

5. Endomysium envelops individual muscle cells and it is composed of collafen fibers.

1. Muscle fiber are actually muscle cells (myocytes) that form muscle tissue,

3. Myofibrils are long protein filaments within the muscle cell responsible for contraction. Actin and myosin are myofibrils that slide past one another and thus change the lengh and the shape of muscle cell.
