The granular mass becomes somewhat stellate, and finally assumes a reticulate form with one more highly refracting nucleoli at the nodal points of the reticulum.
There are usually two, three, or morenucleoli generally situated, as described by Eimer, close to the membrane of the vesicle, the largest of which may measure as much as 0.
Some of the larger of them are not very much smaller than the germinal vesicle of their ovum, while the smallest of them present a striking resemblance to the nucleoli (fig.
They appear to be nucleoli in which a number of smaller nucleoli are originating by a process of endogenous growth, analogous perhaps to endogenous cell-formation.
The nucleoli thus formed are, no doubt, destined to become free.
The above mode of increase for the nucleoli appears to be exceptional.
With reference to the structure of the ovarian ova we may state that the germinal vesicles are provided with numerous nucleoli arranged in close proximity with the membrane of the vesicle.
B), which makes me think that they may possibly be nucleoli which have made their way out of the germinal vesicle.
In some instances the regularity of the arrangement of these fibres is very great, in other instances two central nucleoli are present, in which case the regularity is considerably interfered with.
The contents are clear but traversed by a very distinct and deeply staining reticulum of fibres connected with the several nucleoli which are usually present and situated close to the membrane.
At first one to three nucleoli are present, but they gradually increase in number as the germinal vesicle grows older, and are frequently situated in close proximity to the membrane.
Two or three special nucleoli are present, and form the nodal points of the reticulum, while its meshes are filled up with the clear fluid constituents of the nucleus.
The opposite extreme is reached in many osseous fish where the nucleoli are extremely numerous.
It is at first connected with the nucleoli which form nodal points in it, but this relation cannot always be detected in the later stages.
In the majority of nuclei examined, the number of the enclosed nucleoli proved to be very great, fifty to eighty or more, often some hundreds, the greater their number the smaller their size.
The nucleoli are very different in respect to their form, size, number and arrangement.
The membrane of the vesicular nucleus is thin but rather firm, and contains a rather clear, finely granulated substance, in which numerous nucleoli are usually scattered.
Sometimes the nucleoli were regularly spherical, equidistant, and connected apparently by a delicate network (Pl.
Partial rest stage between first and second maturation divisions, two nucleoli present.
Within the nucleus we find commonly one or two smaller bodies, the nucleoli (Fig.
During this process of the formation of the chromosomes the nucleoli disappear, sometimes being absorbed apparently in the chromosomes, and sometimes being ejected into the cell body, where they disappear.
The nucleii differ also in the number of nucleoli they contain as well as in other less important particulars.
Sometimes the nucleus is penetrated by fine trabeculae, in whose meshes lie the nucleoli (Pl.
Enclosed in the semi-fluid substance of the nucleus are very long and thin cylindrical nucleoli snake-like, contorted, and penetrating into the protuberances of the nucleus.
The number and size of the contained nucleoli are variable even in one and the same species, and stand in inverse ratio to each other, an obvious result of the gradual process of division.
More detailed descriptions, especially with respect to the behaviour of the nucleoli were given by R.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "nucleoli" in a variety of sentences. We hope that you will now be able to make sentences using this word.
