Each myosin thick filament is surrounded by actin thin filaments, and each thin filament is surrounded by thick filaments. Several of these filament bundles make up the functional portion of a muscle cell. It is also important to note that the thin filaments are attached to a very dense protein plate called a Z disc.

When we are stressed, a hormone called cortisol is released, causing many things to occur in our bodies, including accumulating fat, as well as make your skin very dry, oily, wrinkled, or full of acne.
