To bring the same clearness and intelligibility, the same inevitableness and calculability into the world in general, and into the whole realm of nature down to the mysterious law determining the development of the daintiest insect’s wing, and the stirrings of the grey matter in the cortex of the brain which reveal themselves to us as sensation, desire, and thought, this has always been the aim and secret faith of the naturalistic mode of thought.
If trouble in the adrenal cortex starts after puberty, phenomena of the same type, but of a different order, exhibit themselves. A woman, say in the thirties, becomes thus afflicted.
A. Association fibers. C. Commissural fibers. P. Projection fibers. The cell-bodies with which the fiber bundles connect are in the surface layer or cortex.
Among reptiles, the two become adjacent for the first time, and among birds one part occupies the meshes of the other. The size of the cortex varies directly with the sexuality and the pugnacity of the animal. The charging buffalo, for example, owns a strikingly wide adrenal cortex. The fleeing rabbit, on the other hand, is conspicuous for a narrow strip of cortex in its adrenal.
If pregnancy and the consequent placenta do not occur, it shrinks and turns into a scar, the false corpus luteum. The true corpus luteum resembles closely the adrenal cortex in make-up and staining reactions.
Sexual precocity in boys may be produced by a premature overactivity not only of the specific reproductive organs: the testes, but also by an early excess of secretion on the part of the cortex of the adrenal gland or the pituitary gland, or by a too early involution of the pineal or thymus.
The nervous system, controlled by the brain has 3,000,000,000,000 nerve cells, 9,200,000,000 of which are in the cortex or covering of the brain alone. In the blood are 30,000,000 white corpuscles, and 180,000,000,000,000 red ones. Almost 3 pints of saliva are swallowed every day, and the stomach generates daily from 5 to 10 quarts of gastric juice, which digests food and destroys germs.
Sometimes the arterial vessels are so dilated as to impart to the tumour an aneurysmal pulsation and bruit. The enlargement or "expansion" of the bone results in the cortex being represented by a thin shell of bone, which may crackle on pressure parchment or egg-shell crackling.
He verbally dissected her, giving a full and lucid explanation of the nervous system, from the spinal marrow and its termination in the coccyx, up to the cortex of the brain, in which he was of opinion that there was in that case a lesion probably curable amply accounting for the phenomenon present. So clear, indeed, were his remarks that even a layman could follow them.
On the contrary, in the brain the gray cortex, or rind, is less transparent than the white nerve tubules in the centre. The denser fibrous tissues, such as the ligaments of joints and the tendons or sinews of muscles, cast very perceptible shadows, so that when we come to a thick tendon like the tendo Achillis, the shadow approaches even the density of the shadow cast by bone.
