By the time an emotion has fairly got us in its grip so that we are really conscious of it, the blood-supply of half the organs in our body has been powerfully altered, and often completely reversed.
But does histology give any clew to the way in which such isolation may be effected? Attempts were made to find an answer through consideration of the very peculiar character of the blood-supply in the brain. Here, as nowhere else, the terminal twigs of the arteries are arranged in closed systems, not anastomosing freely with neighboring systems.
Subsequently, the sac which incloses the embryo becomes everywhere fastened to the inner surface of the uterus and completely fills the uterine cavity. THE AMNIOTIC FLUID. The great enlargement of the uterus which is so marked a characteristic of the latter part of pregnancy is due in a measure to the luxuriant blood-supply, for better nutrition always causes growth.
There was scarcely enough blood-supply left to the orbit to maintain life in the globe. The man primarily recovered, but ninety-one days from the injury he died of cerebral abscess. There is the record of a curious brain-injury in a man of twenty-two, who was struck on the skull by a circular saw.
It matters not what may be the form of inheritance whether it be of a brain in some way imperfect, or of a deficient blood-supply; it is in any case the inheritance of functionally-modified structures.
When, upon the resumption of a food diet, the vomiting did not cease, the family was alarmed. The family physician was sent for in dismay. But he could do nothing. Flesh-building foods were prescribed, but they accomplished nothing. The vomiting continued, and three weeks following the breaking of the fast Mrs. Meyer died. "The death was put down to a depleted blood-supply, or heart-failure.
As soon as the cavity of the appendix is cut off from that of the intestine, it is of course obvious that infectious or other irritating materials can no longer enter its cavity to cause trouble, although, of course, it is still subject to accidents due to kinks, or twists, or interference with its blood-supply; but these are not so dangerous, providing there be no infectious germs present.
In pondering over what he had learned about collateral circulation and the time required for it to become fully established, Hunter conceived the idea that if the blood-supply was cut off from above the aneurism, thus temporarily preventing the ceaseless pulsations from the heart, this blood would coagulate and form a clot before the collateral circulation could become established or could affect it.
A chief feature characteristic of uterine disease is malnutrition from atrophy a sudden curtailing of the blood-supply from the degeneration of the genital-nerve apparatus and consequent impaired vitality of tissue from defective nourishment.
Here our explanation runs against what we call 'vital power' of the ultimate elements of the body." Professor Conn next analyzes the processes of circulation, and his ready-made mechanical concepts carry him along swimmingly, till he tries to explain by them the beating of the heart, and the contraction of the small blood-vessels which regulate the blood-supply.
