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.
As explained on the previous page (structures of muscle filaments), there are two physical units that are important for the action of muscles. They are thick filaments and thin filaments. Muscle tissue can be described in terms of units called sacromeres.These units are defined in terms of groups of overlapping filaments (the thin and thick filaments previously described). Sacromeres are arrangements of thick and thin filaments.uring Muscle Contraction : The myosin heads on the thick filaments hook onto, and so pull, the thin filaments towards the centre (labelled M-line) of each sacromere. The appearance of this action is shown above as the transistion from relaxed to fully contracted muscle.
