The book provides fundamental new insights in the structure and function of the healthy NeuroMuscular system. Recent findings suggest that the musculoskeletal system that supports movement control on Earth is controlled by unique principles of structural, biochemical and molecular characteristics. Mechanical loading by working against normal gravity helps to support principal structures in bone, muscle and associated subcellular scaffold components. Disuse or immobilization of the body in bed rest on Earth or in microgravity in Space result in considerable loss of bone, muscle and force with...
