Width of the frontal from the middle of the temporal line on one side to the same point on the opposite...104 = 4.1" 4.5". Length of the frontal from the nasal. process to the coronal suture...133 = 5.25" 5". Extreme width of the frontal sinuses...25 = 1.0" 0.9". Vertical height above a line joining the deepest notches in the squamous border of the parietals...70 = 2.75".
Such a simple tissue is called an epithelium or surface-limiting tissue, and the cells are known as epithelial cells. These are united by a very small amount of a cement substance which belongs to the proteid class of material. The epithelial cells, from their shape, are known as squamous, columnar, glandular, or ciliated.
The more detailed study of the body may now be begun by a description of the skeleton or framework which supports the soft parts. Experiments. Experiment 1. To examine squamous epithelium.
In making this estimation, the water is supposed to stand on a level with the orbital plate of the frontal, with the deepest notch in the squamous margin of the parietal, and with the superior semicircular ridges of the occipital. Estimated in dried millet-seed, the contents equalled 31 ounces, Prussian Apothecaries' weight.
Syphilis is an infective disease due to the entrance into the body of a specific virus. It is nearly always communicated from one individual to another by contact infection, the discharge from a syphilitic lesion being the medium through which the virus is transmitted, and the seat of inoculation is almost invariably a surface covered by squamous epithelium.
In consistence they are firm and elastic, or fluctuating, and are incorporated with the overlying skin, but movable on the deeper structures. The orifice of the partly blocked sebaceous follicle is sometimes visible, and the contents of the cyst can be squeezed through the opening. The wall of the cyst is composed of a connective-tissue capsule lined by stratified squamous epithelium.
The soft parts, including the nail, should be reflected towards the dorsum in the form of a flap, the base of the exostosis divided with the chisel, and the exostosis removed. Malignant disease in relation to the nails is rare. Squamous epithelioma and melanotic cancer are the forms met with. Treatment consists in amputating the digit concerned, and in removing the associated lymph glands.
Where it is a mucous membrane of the kind covered by cylinder-epithelium, the cylinders gradually shorten, becoming finally flat, and there results a squamous epithelium: there is a near approach in minute composition to epidermis. Here a tendency towards completion of the type cannot be alleged; for there is, contrariwise, divergence from the type.
In a cloth on a bench opposite were rolled up a portion of the malar bone, some fragments of the os frontis, one entire right parietal bone, detached from its fellow along the sagittel suture, and from the occipital along the lambdoidal suture, perhaps taking with it some of the occipital bone together with some of the squamous portion of the temporal bone.
"You're looking at the Allr, the closest cultural gestalt to us, and somewhere near our level. Now " Something squamous perched on a rock on what seemed to be a barren world. Before it floated bright points of light that were obviously replicas of planets, with tiny lines of light between them, and a shuttling of glints along the lines. The thing seemed to look at them, briefly.
