| What are the two contractile proteins of muscles? | Actin and Myosin |
| What compartmentalizes muscles? | Tough fibrous tissue called the fascia |
| What anchors the myosin fibers to the Z line? | Titin |
| Why do our muscles have elastic properties? | Titin is elastic, so when force is applied to our muscles the titin stretches and unfolds, when force is taken away the titin refolds. |
| How is actin attaches to the Z lines? | Nebulin and intermediate filaments. |
| what is the role of troponin? | It regulates myosin binding by controlling the position of tropomyosin. It is the binding site for Ca+ and when Ca+ binds it causes movement of tropomyosin exposing the myosin binding sites. |
| what does the sarcoplasmic reticulum do? | It is the conduction system for calcium in the muscles. |
