International Medical And Surgical Survey 1922 Vol 4 Classic Reprint

Excerpt from International Medical and Surgical Survey, 1922, Vol. 4 Worthmann endeavored to determine whether the dense, ivory-like texture of the petrosa is ascribable merely to its function as the rein forcing rib of the cranial vault or also to its participation in the func tion of the temporomandibular articulation. For this purpose he studied the cranium in predatory animals as these are destitute of the external pterygoid muscle, and the temporomandibular articulation has the move ment of a simple hinge joint. The muscles of mastication are divisible into 2 groups according to the direction of their pull: (1) an anterior one, consisting of the internal pterygoid and masseter, which transmits the pressure only to the facial skeleton, and (2) a posterior group, represented by the temporal muscle, which transmits it also to the cranium. The action of each muscle may be represented by a single straight line connecting the centers of the surfaces of origin and insertion. In the case of the first 2 muscles, this axis falls vertically on the center of the line connecting the temporomandibular articulation with the contact surface of the last pair of molars; in the case of the temporal muscle, it falls obliquely on the prolongation of this line within the dental arches. Resolved into its components, the one acting in the direction of the temporomandibular articulation is greater than that of mastication pressure. Articular pressure is offset by reinforcements in the skull to which the petrosa belongs. As the temporal muscle is the only muscle transmitting maxillary power to the cranium and thence to the cervical musculature, it is developed most strongly in those animals who are compelled to carry great weights between the maxillas. In man the action of the internal pterygoid serves to compensate for the underdevelopment of the coronoid process and its unfavorable influence on the utilization of the temporal muscle's power with opened mouth, to keep the articular component of the temporal muscle's pressure from the cranium, and to render possible the isolated action of the incisors in biting.

Excerpt from The British and Foreign Medical Review, or Quarterly Journal of Practical Medicine and Surgery, Vol. 4: July-October 1837 The work of Professor Renslow, being written for a popular series, is more adapted to the general than to the medical reader. It contains an extremel clear outline of many departments of the science, and forms an ex t introduction to the study of botany; but it is deficient in those higher and more general views which are so interesting to the advanced student. It cannot be doubted, from the author's high reputation as a botanist, that he could have introduced more of novelty in his illustrations; but any deficiency in this respect is counterbalanced by the lucid manner in which he has stated his Views on several disputed questions of great interest, some of which we shall hereafter notice more particularly.

Excerpt from The British and Foreign Medico-Chirurgical Review, Vol. 4: Or, Quarterly Journal of Practical Medicine and Surgery; July-October 1849 I began to study Reflex Obstetrics in 1842; and the present work is the result of seven years' close and earnest attention to the subject. I may say that during this time, though much occupied by other matters, it has scarcely ever been absent from my waking thoughts.

Excerpt from The Surgical Clinics of North America, Vol. 2: August 1922; Boston Number Her health was much improved by the operation, and she has felt very well until about a month ago, when she began to have severe pain in the epigastrium, with indigestion and loss of appetite. Although her symptoms do not point to any pelvic trouble, we will first examine her to determine the local result of her operation. I find, on bimanual examination, a small, indurated, smooth mass just to the left of and posterior to the cervical stump. It is somewhat smaller than an English walnut. Can you feel what I describe?

Excerpt from Collected Reprints From the Department of Experimental Surgery of the New York University and Bellevue Hospital Medical College, Vol. 3: 1920-1922 Increase in the force or rate or change in the direction of gastric contractions have followed irritation of the gallbladder, duodenum, or appendix, experimentally, and these motor changes have been associated with pathological gallbladders, duodenums, and appendices, clinically.l It may be assumed, subject to further experimental proof, that these organs constitute three of the possible foci of reflex gastric stimulation. Were the nerve paths known along which these impulses travel, it might be possible to explain these motor responses and group other possible causes of gastric motor unrest.
