Document Summary
Muscle tissue is a very heterogenous population of muscle fiber types. Contains 3 basic fibers and these fibers can be classified by their metabolic and contractile capabilities. Metabolically based on primary path for atp synthesis. Tca cycle : uses glucose and fatty acids. Glycolysis is the fastest way to produce atp. Fun fact: the semitendinosus muscle in the pig has both slow and fast twitch muscle. Muscle fiber used in a mixture of fast. Ossification : natural process of bone formation transformation from cartilage. Calcification : impregnation of calcium or calcium salts hardening of tissue. Appositional growth : increased mass by addition of material to the outer surface. Protection to organs : inorganic ions and marrow/immune cells. Determines the body frame and carcass size. Growth and storage functions are under hormonal and growth factor regulation. 30% living tissue elastin, allows the bone to bend without breaking. The formation of bone osteogenesis occurs in both prenatal and postnatal life.
