The cells in question are essentially those which line serous cavities and those which form excretory glands such as the kidneys.
And, again, that serous vessels may be enlarged so as to admit the red globules; and a part that is colourless when in the healthy state may, in consequence, assume a highly red hue when in an inflamed condition.
It has been said that redness is not essential to inflammation; forserous vessels may be altered in size and function by this action, and yet not be sufficiently dilated to receive the red globules of the blood.
Great risk attends interference with bursæ of large size near joints or cysts containingserous or glairy fluid in any situation.
Many of them are due to hemorrhages or to serous effusions in various parts of the body.
Hemorrhages are found in the mucous, serous or muscular layers.
In addition to these hemorrhages there are serous effusions of the muscles similar to those which are found in the pleural and pericardial cavities.
Any or all of the serous cavities may be involved in this hydrops, the order of frequency being pericardium, pleurae, peritoneum, and joint surfaces, especially the knee.

Enough serous effusion in the pia mater to produce a condition which has been called by some writers “serous apoplexy,” I believe never occurs as a primary condition.
As the result of putrefaction, fluids, generally blood-stained, collect in the serous cavities of the body, and should not be confounded with serous effusions occurring during life.
It should be remembered that serous fluid within the membranes of the cord, as also intense congestion, especially along its posterior aspect, is often seen as the result of post-mortem change.

The yolk-sack now, like the allantois which closely wraps it all round, lies loose in a space bounded outside the body by the serous membrane, and continuous with the pleuroperitoneal cavity of the body of the embryo.
Outside the embryo there now remains nothing but the highly vascular allantois and the bloodless serous membrane and amnion.
In L the splanchnopleure has completely invested the yolk-sack, but at the lower pole of the yolk is still continuous with that peripheral remnant of the somatopleure now called the serous membrane.
To this membrane Turner has given the appropriate name of subzonal membrane: by Von Baer it was called the serous envelope.
The serous membrane (or outer primitive amniotic fold) is, by the completion of the cleavage of the mesoblast and the withdrawal of the yolk-sack, entirely separated from the embryo.
Had the whole section been represented the allantois would have been enclosed in a space between the serous membrane (se) and a layer of splanchnic mesoblast below which has also been omitted in fig.
A and B), and its external limb or serous membrane, after separating from the true amnion, soon approaches and fuses with the vitelline membrane.
Joints are developed in the mesenchyme, or that part of the mesoderm which is not concerned in the formation of the serous cavities.
After the joint has thus gone wrong, bleeding and serous effusion take place into it, and it becomes greatly swollen.
If, however, bleeding does not take place, the swelling is not immediate, but synovitis having been set up, serous effusion comes on sooner or later.
Secretions are constantly maintained, during life, from the serous membrane, by the action of the internal exhalants.

In general, the practice of administering drastic purgatives is more serviceable in hydrothorax, and especially in anasarca, or in idiopathic serous inflammation of the peritoneum.
By the hydropic or serous inflammation, obeying the same laws which govern the other degrees of common inflammation, it follows, that upon a higher excitement being superinduced upon it, the serous effusion should cease.
Together with leeches, blisters are to be used, and after the chronic action existing in the serous membrane is subdued by these means, a seton fixed in the integuments of the chest will be found of great utility.
It usually takes place from one portion of the cellular membrane to another; but sometimes from this membrane to the serous tissue of the brain, chest, or abdomen.
The pericardium is a sac composed of two layers--a fibrous membrane on the outside, and a serous one on the inside.
It is inclosed in a loose sac of serous membrane, [Footnote: The mucous membrane lines the open cavities of the body; the serous, the closed.
It is characterized by an itching, burning, reddened eruption, in which a serous discharge exudes and dries into crusts or scales.
There are no characteristic appearances after death save hyperaemia of the brain and blood-vessels of the membranes, with generally serous effusion into the ventricles.
The post-mortem examination showed some hyperaemia of the brain andserous effusion in the ventricles, and there was also tubercle in the pleura.

The outer coat is the serous membrane which lines the abdomen,--the peritoneum (note, p.
The serous membranes form shut sacs, of which one portion is applied to the walls of the cavity which it lines; the other is reflected over the surface of the organ or organs contained in the cavity.
The sac is completely closed, so that no communication exists between the serous cavity and the parts in its neighborhood.
The synovial membranes are almost identical in structure withserous membranes (page 176), but the secretion is thicker and more like the white of egg.
Each lung is covered, except at one point, with an elastic serous membrane in a double layer, called the pleura.
Lining the walls of this cavity, just as in a general way, a paper lines the walls of a room, is a delicate serous membrane, called the peritoneum.
The various serous membranes are the pleura which envelops the lungs; the pericardium which surrounds the heart; the peritoneum which invests the viscera of the abdomen, and the arachnoid in the spinal canal and cranial cavity.
The space between the two membranes is filled with serous fluid.

The two layers thus form between them a Closed Sac a serous cavity (see Fig.
In health the two pleural surfaces of the lungs are always in contact, and they secrete just enough serous fluid to allow the surfaces to glide smoothly upon each other.
The pleura is not much reddened, but by its thickness in some points, its adhesion in others, and the effusion of a serous fluid, it proves how much and how long it has participated in the inflammatory action.
This is an inflammation of the pleura, or the serous membrane which lines the cavity of the chest, and which is deflected over the lungs.
Hæmorrhages from the mucous membranes, and sanguineous suffusions into the serous cavities, such as the pleura or pericardium, may supervene more or less slowly.

The amnion and serous membrane retain their primitive constitution for some time, but gradually become thinner on the ventral surface, where a rupture appears eventually to take place.
The greater part of them disappears, but in the closure of the dorsal parietes the serous envelope plays a peculiar part, which is not yet understood.
A slight consideration of the mode of formation of the membranes, or an inspection of the figures illustrating their formation, makes it at once clear that the yolk can pass in freely between the amnion and serous envelope (vide fig.
These structures no doubt further require investigation, but may provisionally be regarded as homologous with the amnion and serous membrane of Insects.
