Excerpt from book: The preceding paper of Dr. Allen was' first discussed by Dr. Thomas Dwight, of the Harvard Medical School, in the following paper: Mr. President : Dr. Allen d... more »efines morphology as anatomy writ large. The underlying idea of his paper is to plead for a longer, broader, deeper course in anatomy. The tendinous heartstrings of every anatomist will vibrate in sympathy, producing a symphony of musical murmurs. Perchance in some of us one of the factors will be the moderator band of the ruminant which has left its normal place near the apex of the human heart to cross near the middle of the right ventricle. The expert auscul- tator can recognize this cord. It is good for his patient that he should know from anatomy that such a band may be present, and that its sound is no sign of even functional disturbance. The ophthalmologist is none the worse that embryology teaches him the whereabouts of the hyaloid artery which may persist throughout life. Anomalies, therefore, as well as slighter variations, are of practical importance. The surgeon needs to know of the fibrous or muscular band which may cross the axillary artery, that the brachial artery may divide high up the arm (very rarely in the lower third), and that the diverging artery, be it radial or ulnar, almost always runs superficially. A third trochanter, which seems much larger than it is when felt through the soft parts, must not be mistaken for an exostosis, nor a deltoid tubercle of the clavicle for an old fracture. We must not forget that anyone of us may at any time meet with a very rare anomaly. I myself within a few months have seen a case of complete absence of one kidney, the other being of about the usual size and in its proper place. But it is not necessary to turn to anomalies to support the need of a deeper knowledg...« less
