The AnyBody Modelling System, developed by the Denmark-based AnyBody company, is the world’s most detailed ‘musculo-skeletal’ model of the human body, incorporating more than 100 bones and 910 muscles. Here it has been placed on a CAD drawing of a microgravity centrifuge. This simulation took place as part of an ESA project to assess the AnyBody model for use in assessing microgravity countermeasures for astronauts in orbit.
