Sliding filament model of muscle contraction. A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell. Muscles are composed of tubular cells called myocytes, known as muscle fibers in striated muscle, and these cells in turn contain many chains of myofibrils.
Sustainable management is a resource management technique that seeks to make any harvesting or consumption of natural resources as sustainable as possible. Thus, the main goal is to replenish any resources as fast as they are depleted.n order to accomplish its goal, sustainable management often looks at two different factors: the rate of consumption and the rate of replenishment.
