This life size closed back torso is composed of 25 parts that feature the most realistic reproductions of anatomical structures in their most intimate detail. The head is sectioned to expose half the brain. In addition, the neck is dissected to expose muscular, neural, vascular and glandular structures. The thorax and abdomen are completely open, providing an unrestricted view of all internal features. Significant structures are numbered and referenced on the accompanying key. Many additional features are included in the CD-ROM Guide. Separate male and female urogenital systems fit interchngeably into the main portion of the torso.
