What Is bulk REO? Bulk REO is when a lender has so many repossessed properties that it decides to sell them in bulk to investors. The government-sponsored agencies, Fannie Mae and Freddie Mac, as well as the FHA (Federal Housing Administration) have sold REO's in bulk, as have several of the largest banks.
Thick Filaments and its purpose. Thick filaments in a muscle fiber are made of many molecules of the protein myosin. Each myosin molecule has a fibrous tail region and a globular head. For clarity, only one head is shown here. Thin filaments are twisted chains made of the globular protein actin.
Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis. Muscle fibres are cylindrical, and multinucleated.Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber.The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction.uscle fibres are cylindrical, and multinucleated. Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber.
