A heart model is retained in a container for a catheter simulator. The container includes an accommodating unit for accommodating a liquid, having side walls and a bottom surface, a connection unit attached to one of the side walls and retaining the heart model, and an installation part provided on one of the side walls. The installation part is configured to insert a catheter from an outside of the container into the simulated blood vessel of the heart model. The connection unit includes a holding protrusion protruding inside the accommodating unit, and a communicating hole. A front end of the holding protrusion is open so that the heart model is detachable from and reattachable to the holding protrusion by inserting and extracting a terminal of the heart model.

An animal dentistry training and assessment apparatus comprising a sectioned artificial tooth, comprising a crown portion and a furcate root portion, the furcate root portion comprising a plurality of roots; and a base comprising a receiving portion configured to receive and releasably retain each root of the furcate root portion. The sectioned artificial tooth is sectioned into a plurality of sections comprising one or more but not all of said roots of the furcate root portion and part of the crown portion, the plurality of sections being contiguous when the sectioned artificial tooth is received in the receiving portion.

Various embodiments of an anatomical model suitable for microsurgical training are disclosed. The anatomical model includes predetermined ergonomic features that accommodate training of a surgical task.

A three-dimensional model for demonstrating an osteotomy surgical procedure is provided. The three-dimensional model includes a support, a first bone coupled to the support, and a second bone coupled to the support. The first bone includes a body defining a recess including a surface having an embedded magnet, a removable intermediate bone block disposed within the recess, and a removable surface bone block, disposed within the recess, including at least one embedded magnet. The removable intermediate bone block and the removable surface bone block are associated with the osteotomy surgical procedure.
