Concept of Product Life Cycle. First referenced in the 1920s, the product life cycle applies biological knowledge to products. In nature, a seed is planted, begins to sprout, becomes an adult then eventually withers away and dies. The product life cycle focuses on introduction (seed), growth (sprout), maturity (tree) and decline (death) phases. Each phase has its own marketing mix strategy and implications regarding product, price, distribution and promotion.

Each skeletal muscle fiber is a single cylindrical muscle cell. An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering.Each muscle is surrounded by a connective tissue sheath called the epimysium.Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.tructure of Skeletal Muscle. A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.
