Abstract: An anatomical structure model includes a first component defining a first part of the anatomical structure and a second component defining a second part of the anatomical structure. Each of the first and second components define a respective opening and the two components are adapted to be placed in an assembled position to define an insert receiving passage between the first component and the second component. An insert of the model includes an insert peripheral edge structure extending around a periphery thereof, and is adapted to be received in an operating position between the first component and the second component. A connector arrangement detachably connects the first component and the second component in the assembled position with the insert in the operating position.
