The brain is not a single organ, but rather a collection of organs, differing from one another in function even more than in situation, and among them only some are really concerned in the production of thought. 2d. In the medulla oblongata exists a nervous centre called the vaso-motor centre, because of its close relations with the vaso-motor nerves.
This likewise accounts for the increase of the medulla oblongata, which being loaded with more juices than it could send off, swelled in the same manner as the branches of trees, which will grow of a monstrous size, when the sap that runs into them is stopt in its progress.
There is, however, a FOURTH, which subsists, in part, after the voluntary and respiratory motions have ceased, by the removal of the cerebrum and medulla oblongata, and which is attached to the medulla spinalis, ceasing itself when this is removed, and leaving the irritability undiminished.
These variations occur because of a difference in chemical source and determination of the two instincts. While the ovary, stimulated by the thyroid and the adrenal medulla, is the chief determinant of the sex instinct, to the posterior pituitary must be credited the chief hormone of the maternal instinct.
In so far as certain other parts of the brain are concerned medulla, pons, mid-brain, basal ganglia cerebellum we who are human are not essentially superior to the dog, the cow, the elephant or the monkey.
It may be seriously slowed by nervous shock, fear or sudden peripheral contractions, spasm of muscles, or convulsive contractions, or it may be stimulated to greater rapidity by nervous excitement. It may be slowed or made rapid by reflex irritations, and it may be seriously interfered with by cerebral lesions; pressure on the vagus centers in the medulla oblongata will make it very slow.
"The 'thing' you threw out happened to be the cerebellum and medulla of an extremely eminent English Theologian!" "Even so, it was sour," telegraphed the White Linen Nurse in a perfect agony of remorse and humiliation. The telegram took an Indian with a birch canoe two days to deliver, and cost the Senior Surgeon twelve dollars.
It is immediately under the cerebellum, and forms the connecting link between the brain and the spinal cord. It is about an inch and a quarter long, and from one-half to three-fourths of an inch wide at its upper part. The medulla oblongata consists, like the spinal cord, of columns of white fibers and masses of gray matter, but differently arranged.
And Georges Hanquet, attacked by softening of the spinal marrow, passes without transition from agony to perfect health; while Leonie Charton, likewise afflicted with softening of the medulla, and whose vertebrae bulge out to a considerable extent, feels her hump melting away as though by enchantment, and her legs rise and straighten, renovated and vigorous.
In the hand, and more rarely in the foot, when one or other of the main nerve-trunks has been divided or compressed, the joints may become swollen and painful and afterwards become stiff and deformed. Bony ankylosis has been observed. In Affections of the Spinal Medulla.
