Two of the doctors who had formerly attended the patient, and one of whom believed in the rupture of certain ligaments, whilst the other asserted the case to be one of medullary paralysis, had ended by agreeing that this paralysis existed, and that there was also, possibly, some ligamentary injury.
In his brains there are those star-like forms called the cineritious substances; out of these go forth fibers through the medullary substance by the neck into the body; passing through to the outmosts of the body, and from outmosts returning to their firsts. This return of fibers to their firsts is made through the blood vessels.
In cardiac failure, as the systolic pressure falls the diastolic is likely to be increased, and the pressure pulse thus diminishing, allows insufficient blood to go to the medullary centers, and death soon occurs. Therefore, in acute illnesses a sustained pressure pulse gives a better prognosis than a diminishing pressure pulse.
Thus we find corals, originally calcareous, in which not only the general shape, but also the minute and complicated internal organisation is retained in flint. Such a process of petrifaction is still more remarkably exhibited in fossil wood, in which we often perceive not only the rings of annual growth, but all the minute vessels and medullary rays.
The whole animal system may be considered as consisting of the extremities of the nerves, or of having been produced from them; if we except perhaps the medullary part of the brain residing in the head and spine, and in the trunks of the nerves.
You know women, young 'confrere'. To calm this impatience, I spontaneously proposed a consultation, and naturally pronounced your name, which is well known by your fine work on the medullary lesions. I supported it, as was proper, with the esteem that it has acquired, and I have the satisfaction to see it accepted."
After passing a distance many times greater than from the surface to the center of the kidney, the tubule empties its contents into the expanded portion of the ureter. Outer portion or cortex. 2. Medullary portion. 3. Pyramids. 4. Pelvis. 5. Ureter. A. Small section enlarged to show the tubules and their connection with the capsules.
Most of this relatively huge size, which happens in the human alone, and not in other animals, is due to enlargement of the cortex. Should this preponderance of the cortex over the medullary portion not occur in the human, that is, if the proportions remain like those of other animals, the brain fails to develop properly, or an entirely brainless monster is generated.
This peculiar type of pith is observed in living plants of very different families, such as the common Walnut and the White Jasmine, in which the pith becomes so reduced as simply to form a thin lining of the medullary cavity, across which transverse plates of pith extend horizontally, so as to divide the cylindrical hollow into discoid interspaces. Trigonocarpum ovatum, Lindley and Hutton.
But they are far below the true fishes, and form a very interesting connecting-group between them and the lancelet. One can see how closely they approach the latter by comparing a young lamprey with the Amphioxus. The chorda is of the same simple character in both; also the medullary tube, that lies above the chorda, and the alimentary canal below it.
