Book excerpt: Excerpt from The American Journal of Anatomy, 1936, Vol. 20 Morphologically considered, the air-sacs and recurrent bronchi are parts of the bronchial tree, but on account of their importance in the avian lung and their unusual interest they are separately considered in this section. This plan also promotes clearness of description, since, at best, the bronchial tree is very complex. The recurrent bronchi, in particular, should receive special notice, because they have been recently recognized and are of capital importance in the physiological anatomy of the lungs. The name recurrent bronchi has been given to certain bronchial tubes that grow from the air-sacs into the lungs of birds to connect with the other air passages. In this sense they are 'recurrent.' They are outgrowths from the air-sacs, rather than extensions of the bronchial tree from within the lung, and the air-sacs and recurrent bronchi are so intimately related in their development that the two structures should be considered together. In the course of development they unite with twigs of the bronchial tree and thus establish complete circuits with the air passages within the lungs. In the adult lung the air passes from the air-sacs through these recurrent bronchi, entering the lung by a returning current, and, in this sense, the air circuit through these bronchi is a recurrent one.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Journal of Anatomy, Vol. 29: May, 1921 November, 1921 With the present volume The American Journal of Anatomy enters a new phase of its history. A transfer of actual ownership occurred some months ago, but only now have the results of this change actually expressed themselves. The first most noticeable effect is a partial transformation in the personnel of the Board of Editors of The Journal, and a word of explanation and statement of intentions seem proper. The Journal was originally founded by a small group of Anatomists who up to the past year retained ownership and the responsibility for its editorial management. These trustees, along with other members of their Editorial Board, a number of years ago delegated the business arrangements and the publication of The Journal to a central office established by The Wistar Institute of Anatomy. The advantages of this arrangement, both in facilities for publication and distribution of The Journal, have been manifold. The trustees realizing these advantages finally deemed it proper to actually transfer their ownership of The Journal to the Wistar Institute of Anatomy, with the understanding that the editorial management and scientific policy would be arranged for between The Wistar Institute and the American Association of Anatomists. An agreement has been reached between The Wistar Institute and the Association of Anatomists whereby a Journal Committee of the Anatomists has been established, and a proper cooperation of the Institute and the Association in the future affairs of The American Journal of Anatomy is assured. In the scientific policy and purposes of The Journal no change has occurred. The aims and ambitions of the present editors are none other than those of their predecessors.

This book was released on 2018-02-05 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Journal of Anatomy, 1912, Vol. 12 Born's article reviews the earlier development of the cloa eal region in a very complete manner, and the substance is as follows: The entoderm of the enteron comes into direct relation with the surface ectoderm in the pharyngeal and cloacal membranes during the formation of the head and tail folds. Both of these membranes lose their primitive position and become folded into the substance of the embryo through increase in the surrounding mesoderm. The allantois, which is developed dorsally in the mammalian embryo (human and guinea pig excepted), shifts to a ventral position on the gut, and is gradually displaced from its intimate relation to the yolk sac through increase in the amount of mesodermal tissue. The primitive streak is carried to the ven tral surface of the body during the formation of the tail fold, and forms the whole or part of the cloacal membrane. Kolliker Strahl and Bonnet believe that the caudal end of the primitive streak is made up of applied layers of ecto and entoderm, and that it enters as such into the formation of the cloacal membrane. Keibel argues that this primitive rela tion of the ecto and entoderm is lost through interposition of mesoderm; the latter disappearing later with restoration of the original two layered condition.

Download or read book The American Journal of Anatomy Vol 14 written by Charles R. Bardeen and published by . This book was released on 2015-08-05 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Journal of Anatomy, Vol. 14: 1912-1913 The granules to be found between the myo-fibrils or muscle columns of cross striated muscle, although mentioned by Henle ('41) were first described in detail by Kolliker ('57) who called them 'interstitial granules.' He applied the term to both fat droplets and true interstitial granules, the latter being of a nonfatty nature. This paper presents observations concerning the structure of striated muscle with especial reference to interstitial granules and fat droplets, including also a brief discussion of their general occurrence, chemical nature, and physiological significance. A number of important communications dealing with the interstitial granules have included a somewhat comprehensive review of the literature, namely, Retzius ('90), Arnold ('09), Holmgren ('10), Prenant ('11), and Bell ('11). As several of these papers are of recent date I have thought best to omit a chronological review and shall discuss the literature only in so far as its subject matter has a direct bearing on the topics treated in this paper. According to Kolliker both fat droplets and true interstitial granules are of wide distribution, occurring in vertebrate muscle and also in insect muscle. A few observers have denied the existence of two general types of interstitial granules, especially in vertebrate muscle, but usually the work of Kolliker has been confirmed in this respect. My observations are in accord with those of Kolliker and I shall likewise designate the types of granules as true interstitial granules and fat granules or fat droplets. For the present it may be said that true interstitial granules, at least for the most part, are not completely soluble in absolute alcohol and not readily stained by fat stains such as Scharlach R, while the fat droplets are easily soluble in absolute alcohol and take the fat stains. This does not necessarily mean that the true interstitial granules contain no fatty substance nor that the fat droplets are composed wholly of fatty substances. Under normal physiological conditions the muscle fibers of both skeletal muscle and cardiac muscle of vertebrates may, and usually do, contain true interstitial granules as well as fat droplets.

During the formation of the acrosome these granules are arranged in a circle around the acroblast and lie close to the nuclear membrane. This arrangement is a constant and striking one (fig. The nature and fate of these granules are not known. Possibly they are related to the chromatoid bodies of other animals.

All of the infinite number of positions which the bones entering into the hip and knee joints can take with respect to each other can be reached by appropriate muscular action. It would be, however, impossible to determine experimentally the exact method of action of each of the muscles which takes part in placing the leg in each of these innumerable positions, or to ascertain what would be the action of each of the muscles when the leg occupied each of these positions.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Journal of Anatomy, Vol. 23: 1918 A careful examination of the ovary Of a bird which has been actively laying shows three kinds of structures: the yolks of various sizes indicating different stages of development, the discharged follicles in various stages of regression, and the atretic follicles or degenerating eggs of different sizes. These are all easy to identify when they are large enough to protrude far from the surface of the ovary, that is, when they are larger than 2 or 3 mm. In diameter. Under this size, it is impossible to distinguish the discharged follicle from the atretic. Both of them show a yellow or orange spot in the center. The ques tion naturally arises whether these yellow spots are homologous in structure and origin with the mammalian corpus luteum. They never develop into a large mass like the corpus luteum of the mammal. They have the color of the spots on the cow ovary which indicate remains of old corpora lutea. In order to interpret these yellow spots, a study has been undertaken of the progressive and regressive changes in the cell structure of egg follicles in different conditions, undischarged, discharged and atretic.
