Historical Examples of spireme
The spireme here, as also in figure 99, is fine and closely interwound.
Figure 55 shows the spireme segmented and split longitudinally.
In iron-hæmatoxylin preparations this pair is often obscured by parts of the spireme which are tangled around it.
As in most of the other species of Coleoptera, the unequal pair is not distinguishable until the spireme stage.
It is closely applied to the nuclear membrane and is connected with an end of the spireme (figs. 51-54).
- cytology the tangled mass of chromatin threads into which the nucleus of a cell is resolved at the start of mitosis
