A. different stereo motion
pictures of a reconstructed field of synaptic bodies inside a Sprague-Dawley
rat pinealocyte with a section as background
The animations demonstrate the three-dimensional
morphology of 7 synaptic bodies (sbs). They all are ribbons, some are strongly
bent, one seems to have resulted from two
fused sbs. In order not to show the structures
as closely as possible to their true shape no interpolations or smoothing
algorithms were applied. Two sbs look somewhat
disrupted due to fact that they were nearly sagittally
cut in the original sections. All sbs are more or less bent in at least
one direction and only two are completely contained in
the investigated tissue volume. Also note the
deep invagination of the cell membrane close to the field and several clathrin
coated vesicles. The oriented stack of original images
from which the reconstructions were done is shown
in C.

D. stereo animation in 3D "true colour", i.e.
original grey tone as in the micrographs, from another reconstructed area
Three plate-like SBs close to the
membranes of two adjacent cells one of which clearly shows the pentalamellar
structure of SBs that is only visible when they are exactly seen from the
direction of their long axis, i.e., if they are positioned exactly at right
angle to the section plane. |
