A dynamically-changeable abdominal simulator system comprises a patient manikin having an abdominal cavity covered by a sheet of synthetic skin, an array of inflatable elements emplaced within the abdominal cavity covering respectively distinct areas of pressurization of the abdominal cavity and supplied with pressurized medium under separate and independent inflation control for each of the inflatable elements in order to simulate a wide range of abdominal ailments and/or conditional expressions thereof. An inflation manifold and an electronic control module operable therewith control the supply of pressurized medium to the inflatable elements. The electronic control module can communicate with an external computer that provides a graphical user interface (GUI) for the user to control the training simulation routines to be performed on the manikin.
