These advancing endothelial tubes join with those on the opposite side of the wound, and thus the new forming tissues are supplied with blood vessels.
From the loops of the occluded capillaries, at the sides of the wound, spring buds of endothelial cells, becoming thicker and then hollow as they extend, blood cells forming in them and blood entering them also from behind.
When phlebitis begins, a thrombus forms because of the destruction of the endothelial coat, and this clot may be absorbed or organized.
The endothelial cells lining the divided blood vessels multiply and take an active part in the process.
It is claimed by some that small openings exist in the walls of the vessels, between the endothelial cells which line them, to which is given the name of stomata.
Blood has the property of clotting, if it comes in contact with anything but the natural endothelial lining of the vessels.
In suppurative inflammation, pus is produced by emigration, and also by the detached endothelial cells.
When the serous and synovial membranes are attacked by inflammation, the stage of congestion is accompanied by exudation of serum and fibrin from the surface, and the endothelial cells become swollen and detached in large numbers.
These cells are derived from various cellular elements normally present in the body: leucocytes, endothelial cells, connective-tissue corpuscles, and any and all cells in the body which possess the power of ingesting bacteria.
The uninuclear cells are partly lymphoid, partly large epithelial or endothelial cells; these are called epithelioid cells.
She sighs a great deal, she has low spirits, and her arms and legs become numb so frequently that she fears palsy or paralysis.
All the school hours are employed in reading, drawing, music, and other brain work, while the evenings are devoted to preparing lessons for the following day.
The synovia owes its lubricating property to mucin, derived from the solution of the endothelial cells on the free surface of the synovial layer.
Microscopically, it may contain some large endothelial cells and a few lymphocytes, or may be entirely devoid of cells.
This was formerly believed to be an endothelioma derived from a proliferation of the endothelial cells lining the lymph spaces and blood vessels of the gland.
They have numerous endothelial valves, formed of two crescentic segments allowing the lymph to pass toward the root of the neck.
Leucocytes also are capable of passing through or between the endothelialcells of the lymph capillary.
Lymph spaces are mere spaces in the connective tissue, which usually have no special lining, though sometimes there is a layer of endothelial cells like those of the lymphatic and blood vessels.
Closely resembling these cells are those known as endothelial (see later).
By means of endothelial or mesothelial membranes the surfaces of the parts covered by them are rendered very smooth, so that movement over the surface is greatly facilitated.
These cells develop from that portion of the mesoderm known as the mesothelium, and are therefore frequently termed mesothelial, though by many they are also included as endothelial cells.
The last two are probably the same process, the connective tissue having its origin in the proliferated endothelial cells.
The essential portion of any blood vessel is the endothelial tube, composed of flat cells cemented together by intercellular substance and having no stomata between the cells.
The intima is a thin line composed of endothelial cells.
Capillaries These are endothelial tubes in the substance of the organs, the tissue of the organ giving them the necessary support.
Most internal of all is a layer of endothelial cells, which form the free surface over which the blood flows.
The sections show proliferation of endothelial cells, the formation of numerous giant cells quite unlike those of tuberculosis and a progressive fibrosis.
The layer at the bottom of the tube consists for the most part of polymorph leucocytes, and proliferated connective tissue and endothelial cells (pus corpuscles).
A deposit of urate of soda beneath the endothelial covering of tendons or of that lining their sheaths is commonly met with in gouty subjects.
There is no endothelial lining, and the fibrous tissue of the wall is in immediate contact with the colloid material in the interior, which appears to be derived by a process of degeneration from the surrounding connective tissue.
I find between the dorsal bands of longitudinal fibres a vessel in a space shut off from the body-cavity by a continuation of the endothelial lining of the latter (fig.
It is lined by a delicate endothelial layer, and is not divided into compartments nor traversed by muscular fibres.
The vessel has definite walls and an endothelial lining, but I could not make out whether the walls were muscular.
Such tumors are to be regarded as of an endothelial rather than epithelial character, and as such their histogenesis falls under the general laws of the development of tissues.
A granulation-tissue is formed at the periphery, which extends into the infarcted region, very much as the endothelial and vascularized growth extends into a thrombus.
Polymorphonuclear leukocytes and swollen endothelial cells from acute infectious non-tuberculous pleuritis (Percy Musgrave; photo by L.
Endothelial cells generally predominate in carcinoma, but are accompanied by considerable numbers of lymphocytes and red blood-corpuscles.
Endothelial cells from transudate or mechanical effusion (Percy Musgrave; photo by L.
Predominance of endothelial cells, few cells of any kind being present, indicates a transudate (Fig.
This fibrinous effusion encloses, primarily, hardly any cellular elements, and only a few cast-off endothelial cells are to be found in it.
The inner surface has the appearance of a serous membrane, and when examined microscopically is seen to consist of a layer of squamous endothelial cells.
Others of the endothelial cells show a great tendency to form muscle fibres.
There is further a great tendency for the endothelial cells to form muscles, and this is especially pronounced in the small arm-sinus, where a conspicuous muscle is built up.
Some of the endothelial cells lining the coelom are ciliated, the cilia keeping the corpusculated fluid contents in movement.
In the absence of plain muscular fibres contraction and dilatation of the capillaries can only be effected by a corresponding contraction and expansion of the nuclei of the endothelial cells.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "endothelial" in a variety of sentences. We hope that you will now be able to make sentences using this word.
