Effect of spaceflight on the human body of muscle fibre prominent in muscles also change. Slow twitch endurance fibres used to maintain posture are replaced by fast twitch rapidly contracting fibres that are insufficient for any heavy labour. Advances in research on exercise, hormone supplements and medication may help maintain muscle and body mass. Bone metabolism also changes. Normally, bone is laid down in the direction of mechanical stress. However, in a microgravity environment there is very little mechanical stress. This results in a loss of bone tissue approximately 1.5% per month especially from the lower vertebrae, hip and femur. Due to microgravity and the decreased load
Body snatching wanted to identify every bone in the human body and reconstruct it like a jigsaw puzzle. At the time, there was only one set of text books about the body at Vesalius's disposal, written by Claudius Galen 1300 years earlier. Vesalius made over 200 corrections to Galen's book based on what he had learned from dissecting stolen bodies, and ignited a new age of modern medicine. For over 200 years, the city of Kolkata, in the north-eastern region of India, has been known to be the center of a network of bone traders who remove skeletons from graveyards in order
