The next step is the disappearance of the nuclear membrane so that the segments lie apparently free in the protoplasm of the cell.
It is closely applied to the nuclear membrane and is connected with an end of the spireme (figs. 51-54).
But the egg must be in the first stages of maturation to the extent that the nuclear membrane must be already dissolved.
Figure 81 is a slightly later stage with the spindle-remains massed against the nuclear membrane.
This body is often applied to the nuclear membrane and connected with the spireme (figs. 84-86).
During the various phases of the growth stage (figs. 230-232) the element x is again applied to the nuclear membrane.
The nuclear membrane then disappears and fibrillar cell-plasma or cytoplasm invades the nuclear area.
nuclear membrane n.
The double-layered membrane enclosing the nucleus of a cell. Also called nuclear envelope.
