Muscle As Food

There are four types of biological tissue—epithelial, connective, muscular, and nervous. Muscle tissue is a major component of the animal and is valued as a food because of the nutritional value afforded as well as satiety. Skeletal muscle is voluntarily controlled and identified histologically because it is striated and multinucleated. In mature muscle the nuclei are located peripherally in the cell, and they do not divide. Cardiac muscle cells are also striated, but they are mononucleated and have, in addition, a distinguishing feature called the intercalated disc. The intercalated discs are found at opposing ends of the cardiac muscle cells and help to maintain cohesion of one cell with another. Smooth muscle cells are spindle shaped, involuntary, nonstriated, and mononucleated. Smooth muscle is located in such places as blood vessels, the digestive tract, and ducts of glands. Smooth muscle controls the internal environment of an organism by moving or controlling movement of substances through various routes by peristaltic movement. Cardiac muscle is responsible for pumping blood around, and striated muscle moves the organism or parts of it.
