Most medical curricula rely on human bodies for teaching macroscopic anatomy.
Over the past 20 years, plastination has become an important means of
preservation of organs, for well dissected specimens or for body slices. Here,
several critical points regarding body donation with legal and ethical
considerations for long-term preservation, the use of cadavers in teaching and
the preparation of plastinates as an additional teaching tool will be discussed.
Silicone S10 is the gold standard in the preparation of plastinates. An important
point to respect is the preparation of specimens, since only very well dissected
body parts or excellent tissue sections should be plastinated to show the
extraordinary aspects of the human anatomy. The preparation of thin and
transparent sections and preservation with P40 polyester provides an additional
technique to prepare resistant body slices. A selection of samples prepared by
S10 and P40 are shown and compared. In addition, Prussian or Berlin blue staining
of brain slices is shown to discriminate better between gray and white matter and
demonstrate neuroanatomical structures. These plastinates have been used for many
years in teaching first- and second-year medical students and have not lost their
appeal. Students and staff appreciate the use of such plastinates. One of the
advantages is that their use is not restricted to the dissection hall; slices and
body parts can be used in any lecture room or in small group teaching. Therefore,
ethical and legal questions need to be addressed regarding their specific use.
Plastinates do not replace the traditional dissection courses, since students
learn best the anatomical features of a given region by hands-on dissection and
by exploratory anatomy. Furthermore, plastinates are more rigid and do not allow
demonstration of hidden structures; they also become more cumbersome for
endoscopy or are too rigid for demonstrating mechanical features of joints.
However, although not a replacement for traditional dissections, plastination
provides an additional tool for long-term preservation and for teaching human
anatomy.
