some muscles especially the striated muscles are made up of two kinds of proteinaceous fibres known as Actin and Myosine. These fibres are contractile in nature and different in colour due to differential quantity of myoglobin ( a kind of pigment). Due to these pigments the striations appear in muscles.

The striations are due to the fibers which allow muscles to contract. Those fibers are the think and thin filaments and their arrangements and anchoring points in the myofibriles.

The repair of the micro-tears which occur due to working out. As with metal, the "weld" is stronger than the original piece of metal (or muscle). Of course, you do have to allow time for the muscle to repair itself. If you keep working out too hard too often, you keep tearing the tear and the muscle never gets a chance to knit (repair itself).
