In the young Jacare mentioned above, I found the dermis to be distinguishable into two layers.
In consequence of the matting under the quadrate surface of each scale, the dermis has a peculiar facetted aspect, quite apart from any osseous deposit.
A corresponding arrangement of the bundles of connective tissue has long been known to obtain in the dermis of Fishes and Batrachia.
A loose interweaving of the three elements is areolar tissue, the chief fabric of mesentery, membrane, and the dermis (beneath the epidermis).
From the mesoblast the muscles, the dermis genital and excretory organs, circulatory fluid and apparatus, any skeletal structures; and all connective tissue are derived.
The leather trades use only the dermis (corium) or true skin for the manufacture of leather, and as we have noted (Part I.
There remains the dermis or second layer of skin which is also of value for identification purposes.
In cases in which the epidermis has been lost and there remains only the dermis or second layer, there will usually be shrinkage with the same results.
It is well to bear in mind the fact that the dermis or epidermis may have undergone certain physical changes and that in order for the fingerprint examiner to make a proper comparison he must know the changes which can and do occur.
The prepared skin is placed between two pieces of glass pressed together in order to flatten the skin or dermis and remove creases.
Transmitted light is used in cases in which the skin has peeled off or in which the dermis has been removed, cut, and scraped thin so that light will go through.
Epidermis or outer layer of skin commencing to peel from dermis or second layer of skin, result of decomposition.
From this coil the tube passes upwards through the dermis in a wavy course until it reaches the cuticle, which it penetrates with a number of spiral turns, at last opening on the surface.
The convoluted gland is seen surrounded with big fat-cells, and may be traced through the dermis to its outlet in the horny layers of the epidermis.
There is a watery infiltration from the minute capillaries and the surrounding tissues between the dermis and the epidermis, causing the latter to loosen and if touched to slip and tear away from the dermis or true skin.
The network of tough fibers which this tissue supplies, forms the essential body of the dermis and gives to it its power of resistance.
The cuticle adheres to the nail around its entire circumference so that the covering over the dermis is complete.
On the outer surface of the dermis are numerous elevations, called papillæ.
The epidermis is the main protective agent against attacks of germs, but should the epidermis be broken, they meet with further resistance from the fluids of the dermis and the white corpuscles of the blood.
Only the part next to the dermis is made up of living cells.
A papilla of the dermis makes its appearance, the outer layer of which gradually calcifies to form the dentine and osseous tissue.
A small papilla of the dermis grows into the inner end of the epidermic process when the hair is first formed.
The scales consist of papillae of the dermisand epidermis; and are covered by a thickened portion of a two-layered cuticle, formed over the whole surface of the body from a cornification of the superficial part of the epidermis.
This is the case, as is well known, in the common existing Armadillos, in which the hair is only implanted in the dermis between the separate parts of the armour.
A =placoid scale=[3] is developed on a papilla of thedermis which projects outwards and backwards, and is covered by the columnar Malpighian layer of the epidermis.
The hard parts of a tooth commonly enclose a central pulp-cavity into which projects the pulp, a papilla of the dermis including blood-vessels and nerves.
The superficial layer of the dermis is formed into a series of minute, conical elevations, or papillæ, projecting into the deep portion of the cuticle, from which they are separated by a very fine transparent membrane.
The sweat glands of the horse, like those of man, are composed of simple tubes, which extend down through the cuticle and dermis in a spiral manner, and are coiled into balls in the deeper layer of the true skin.
The nerves of my dermis were working overtime when suddenly I had the most frightening experience of my life.
Concealed in the dermis of the lips are tiny, highly sensitized nerve ends which send sensations to the brain.
