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.

The structure in order from superficial to deep is the following:

  • Epimysium is the membrane that is responsible for surrounding the entire surface of the muscles of the heart, arms, legs, and trunk.

  • Perimysium is the muscular layer, made up of connective tissue, which is located between the epimysium and endomysium layers, and which has the function of covering the muscular fascicles.

  • Fascicles of the muscles are a set of cells that intervene in the function of the muscle, they are surrounded by a layer called the perimysium.

  • Endomysium is the connective tissue membrane that is located inside the muscles, and that unlike the perimysium that surrounds fascicles, this separates each muscle cell.

  • Muscle fiber is the cell of muscle tissue.

  • Myofibrils are small muscle fibers, they are cells that have the function of participating in the movement of each skeletal muscle, they are composed of actin and myosin proteins.

Therefore, we can conclude that the structure in order from superficial to deep is epimysium, perimysium, fascicles, Endomysium, Muscle fibers and finally mayofibrils.
