Page 84 - ... the older description, the motor power driving the bolus downward through the pharynx is derived from the contraction of the pharyngeal muscles, particularly the constrictors, which contract from above downward and drive the food into the esophagus. Kronecker and Meltzer,* however, have shown that the contraction of the mylohyoid muscle in the floor of the mouth is the most important factor in this act of shooting the food suddenly through the pharynx into the esophagus. The contraction of this...
Page 212 - It is well known also that many foreign substances— drugs, flavors, etc.—introduced with the food are secreted in the milk. An average composition is: proteids, 1 to 2 per cent.; fats, 3 to 4 per cent.; sugar, 6 to 7 per cent.; salts, 0.1 to 0.2 per cent. The fact that casein and milk-sugar do not exist preformed . in the blood is an argument in favor of the view that they are formed by the secretory metabolism of the gland cells. The special composition of the milk-fat and the histological appearance...
Page 179 - Contraction of the pupil, due to dominance of the concentric muscles, on the other hand, results from influences which (a) irritate the third nerve, or (b) depress the cervical sympathetics. Brain tumors, meningitis, and certain drugs, such as eserine, are instances of the former; aneurisms (by pressure) and opium of the latter.
Page 7 - No anatomical research can pierce to the secret of broken coordinations, and yet it is in these that a great part of disease begins, or comes eventally to consist." "Every organism, whether we call it diseased or well, presents itself to our view as a web of interwoven 'energies,' which in order to study them by anatomic means, we must break artificially into fragments that have, in reality, no correspondingly separate existence.
Page 179 - Minert's fibres. Wernicke Pupillary Reaction is a test for determining the location of an injury to the optic tract, (usually employed in cases of hemianopsia).
Page 179 - Mydriasis (dilation of the pupil) is caused by any condition which (a) paralyzes either...
Page 2 - ... disease-complex, and which too often represent the last structural changes wrought by disease, rather than the functional derangement in which disease usually has its beginnings. The spirit of the times calls for a prophylactic type of diagnosis — one that shall detect disease in its functional outposts. It is of prime importance that the diagnostician be able to reason back his symptoms to their functional premises, and to state his pathologic condition in terms of physiology. It is of equal...
Page 29 - The pressure of the atmosphere is equal to a column, of mercury 760 mm. high, and is expressed as 760 mm.
Page 180 - The Wernicke Pupillary Reaction is a test for determining the location of a lesion of the optic tract in cases of hemianopsia. If the light reflex is present in the blind part of the eye, then the lesion is back of the corpora quadrigemina ; if absent, it is in front of these ganglia ; because at that point the reflex path leaves the optic tract to go to the fourth ventricle, the reflex arc. Hippus, a periodic and visible contraction and expansion of the pupil, due to alternate excitation and inhibition,...
Page 7 - ... mutual relations with other branches of medicine which have undergone similar expansion. It is in the hope of contributing, however feebly, to the re-establishment of these neglected relationships upon a practical clinical footing that this work on applied physiology is offered.
