But it must be borne in mind that all the nucleated masses of which the blastoderm consists are in continuity with each other and with the sparse protoplasmic reticulum of the subjacent yolk.
In this manner nucleated masses of protoplasm are continually being added to the periphery of the blastoderm and assisting in its growth.
The result is to give rise to a nucleated network or foam-work of protoplasm, ramifying through the yolk-particles and containing these in its meshes.
Microscopically, it was found that the placental villi were filled with small nucleated cells, which were especially abundant in the centre of the villous spaces along the axis where the vessels usually take their course.

The nucleated village and the vill of scattered steads, 15.
The outlines of our nucleated villages may have been drawn for us by Germanic settlers, whereas in the land of hamlets and scattered steads old Celtic arrangements may never have been thoroughly effaced.
On the one hand, there is what we might call the true village or the nucleated village.

Sometimes a fewnucleated red cells and myeloblasts are seen; megaloblasts are also reported.
In the course of the further development the two ends of the column become the blind ends of the ovary, and the axial tissue they contain forms the germinal tissue of nucleated protoplasm.
In the Ichthyopsida most of the protoplasm with the nuclei is carried to the periphery, where it forms a special nucleatedlayer sometimes divided into definite epithelial-like cells (fig.
He sharply castigates the one-sidedness and impetuosity of the mechanical theory, as in Haeckel's discovery of Bathybius and of non-nucleated bacteria.
The epithelium consists of scattered nucleated cells, rounded or oval.
In the very finest branches the tube loses its thread, the chitinogenous cells become irregular, and the intima is lost in the nucleated protoplasmic mass which replaces the regular epithelium of the wider tubes.
By division of the nuclei of the sperm cells spermatozoa are formed, which have at first nucleated heads and long tails.
The chitinogenous layer of the tracheal tubes is single, and consists of polygonal, nucleated cells, forming a mosaic pattern, but becoming irregular and even branched in the finest branches.
Immediately in front of each constriction is the interventricular valve, a pear-shaped mass of nucleated cells, hanging down from the upper wall of the heart, and inclining forward below.
Where the tube suddenly widens, large rounded and nucleated masses of protoplasm appear, interspersed with nuclei entangled in a network of protoplasm.
The circumstance, that in certain anæmias the early stages of the nucleated red corpuscles are variously polychromatic, was evidence for this opinion.
Pugliese asserts that in the hedgehog after splenectomy the nucleated giant cells pass into leucocytes by amitotic nuclear division.
The nucleated or bone-marrow elements and the large mononuclear cells remained continuously at the same level during the whole period.
Possibly they form an early stage of development of the nucleated red blood corpuscles, as the deeply staining and homogeneous protoplasm seems to indicate.
For some time past two views, almost diametrically opposed, have been in existence with regard to the nature of the change of the nucleated to the non-nucleated erythrocytes.
In the spleen of normal mice nucleated red blood corpuscles are seen in relatively large numbers; in the rabbit they are less numerous and often only to be found with difficulty.
The polychromatophil degeneration can frequently be observed in nucleated red blood corpuscles, particularly in the megaloblasts.
Since the fundamental work of Neumann and Bizzozero, the nucleated forms have been generally recognised as the young stages of the normal red blood corpuscles.
Traced back to its earliest state, the nettle arises, as the man does, in a particle of nucleated protoplasm.
It consists of a non-nucleated crystalline cone developed from embryonic cells, and is enveloped in three tiers of large nucleated cells.
The outer ends of the cells are nucleated and are continuous with the fibres of the optic nerve, which passes from the outer surface of the bottom of the cup to the brain.
The central part of the body next becomes transformed into a material composed of clear non-nucleated vesicles.
In the Frog the passive blastophor also occurs as a nucleated mass of protoplasm on the outer side of the spermospore.
In the Earthworm the blastophor forms a central non-nucleated portion of the spermospore; and the whole periphery of each spermospore becomes converted into spermoblasts.
It is moreover probable that a germogen of nucleated protoplasm is less common than is often supposed: it being a matter of great difficulty to determine the structure of the organs usually so described.
They are granular nucleated cells, and, as was first shewn by von Siebold, are remarkable for exhibiting spontaneous amoeboid movements.
The peripheral protoplasm next becomes separated off as a nucleatedlayer (fig.
The ovum in Sycandra as in other Spongida has the form of a naked amoeboid nucleated mass of protoplasm.
In the Malacostraca they are sometimes simply spherical (Squilla), while in Astacus and a large number of Decapoda they are composed of a nucleated body with stellate rays.
The uppermost part of the egg-tube is formed, as in the previous type, by a mass of nucleated protoplasm, but the germinal cells formed from it do not all become ova.
The nuclei in these cells increase in number, and a nucleated peripheral layer of each cell becomes separated from the central part, which also contains nuclei.
In the lower part of the germogen the nuclei are larger, and become separated off from the nucleated protoplasm above, as distinct cells with a thin layer of protoplasm round the germinal vesicle.
At this period the central granular mass develops a number of nucleatedcells on the inner surface of the so-called cuticle.
Soon after the intrusion of the parasite the infested muscular fibre loses its original structure, the fibrillæ collapse into a finely granular substance, whilst the muscular corpuscles change into oval nucleated cells.
This type of protein is characteristic of all cell nuclei, and is particularly abundant in the highly nucleated secreting cells of the glandular organs, such as the liver, pancreas, and the thymus gland.
They are nucleated cells, the nucleus going by the special name of the germinal vesicle and the nucleolus the germinal spot.
Under the microscope cartilage is seen to consist of a matrix, or base, in which nucleated cells abound, either singly or in groups.
In brief, then, a cell is a mass of nucleated protoplasm; the nucleus may have a nucleolus, and the cell may be limited by a cell wall.
If the body be studied in its development, it is found to originate from a single mass of nucleated protoplasm, a single cell with a nucleus and nucleolus.
When we carry back the analysis of an organized body as far as we can, we find every part of it made up of masses of nucleated protoplasm of various sizes and shapes.
In all animals and plants above the lowest the germ is a nucleated cell, using that term in its broadest sense; and the first step in the process of the evolution of the individual is the division of this cell into two or more portions.
Again, a true germ is either devoid of any structure discernible by optical means, or, at most, it is a simple nucleated cell.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "nucleated" in a variety of sentences. We hope that you will now be able to make sentences using this word.
