Perineum
In the second lecture of the series, the focus is on
the perineum. This is the region between the thighs and corresponds to
the subfloor of the pelvis from which is suspended the external genitalia.
This is a particularly difficult area to dissect because the structures
are small and condensed into an extremely compact space. This region
is taught as a series of layers comprising two pouches. But many of the
contents of these pouches are essentially invisible by conventional dissection.
We have designed a tutorial that allows the students
to build the perineal structure from the pelvic diaphragm out or from the
outermost fascial layer in [Figure 8]. The
layers can be moved sequentially to allow views of deeper or more superficial
layers respectively [Figure 9].
Images of this region obtained from the Visible Human
[Figure10] show spectacular detail and the important
anatomical structures are well illustrated. The male perineal data
gives the student an opportunity to view structures that otherwise go undissected
and poorly understood. It should be possible to separate these structures
from the Visible Human and incorporate them into the same sort of tutorial
as we have generated from illustrations [Figure 9,
Figure 10]. Once this area is built as separate
components other structures can be added and correlations made with internal
pelvic structures of the urogenital system.
