The Anatomical Record (Anat Rec )
The Anatomical Record is an official publication of the American Association of Anatomists whose purpose is to rapidly publish new discoveries in the morphological aspects of molecular cellular systems and evolutionary biology. Emphasis will focus upon major new findings in the anatomical consequences of gene disruption activation or over expression upon cell tissue or organ architecture. The journal recognizes the importance of descriptive studies in contemporary research particularly when framed in the context of experimental models or questions. An important priority will be those discoveries and new advances made through the use of imaging modalities that range from those that image real-time signalling processes to ones that image protein or gene expression in individual cells tissues or whole organisms. Papers will be accepted dealing with functional morphology of any vertebrate organ system including those with a developmental comparative or evolutionary theme. With respect to developmental biology our sister journal-- Developmental Dynamics --focuses on biochemical and molecular mechanisms of vertebrate and invertebrate development. Our area of coverage will be directed primarily to the organ or system level where descriptive studies of normal and abnormal development may become an important consideration in characterizing phenotypes. In addition timely reviews of important topics related to Anatomy and its subdisciplines will be regularly included. Discontinued - now The Anatomical Record Part A and B.

ABSTRACT: Early Miocene sloths are represented by a diversity of forms ranging from 38 to 95 kg, being registered mainly from Santacrucian Age deposits in southern-most shores of Patagonia, Argentina. Their postcranial skeleton differs markedly in shape from those of their closest living relatives (arboreal forms of less than 10 kg), Bradypus and Choloepus. In order to gain insight on functional properties of the Santacrucian sloths forelimb, musculature was reconstructed and a comparative, qualitative morphofunctional analysis was performed, allowing proposing hypotheses about biological role of the limb in substrate preferences, and locomotor strategies. The anatomy of the forelimb of Santacrucian sloths resembles more closely extant anteaters such as Tamandua and Myrmecophaga, due to the robustness of the elements, development of features related to attachment of ligaments and muscles, and conservative, pentadactylous, and strong-clawed manus. The reconstructed forelimb musculature was very well developed and resembles that of extant Pilosa (especially anteaters), although retaining the basic muscular configuration of generalized mammals. This musculature allowed application of powerful forces, especially in adduction of the forelimb, flexion and extension of the antebrachium, and manual prehension. These functional properties are congruent with both climbing and digging activities, and provide support for proposed Santacrucian sloths as good climbing mammals, possibly arboreal or semiarboreal, being also capable diggers. Their climbing strategies were limited, thus these forms relied mainly on great muscular strength and curved claws of the manus to move cautiously on branches.

ABSTRACT: The detailed morphology of the renal nerves in mice has not been reported previously. The aims of this study were to describe the general morphology of the extrinsic renal nerve in C57BL/6 mice, and determine its morphometric parameters. The major renal nerve innervating the left kidney was isolated in five mice. Thin sections of the nerve segments were then examined by transmission electron microscopy. The renal nerve averaged 35.4 +/- 3.6 (S.E.M.) microm in diameter and 741 +/- 104 microm in area. The renal nerve contained an average of 830 +/- 169 unmyelinated fibers and only 4.6 +/- 1.7 myelinated fibers. The axon diameter of myelinated and unmyelinated fibers averaged 2.2 +/- 0.3 microm and 0.76 +/- 0.02 microm, respectively. The diameter of the unmyelinated fibers ranged from 0.3 to 2.0 microm, and the distribution histogram was unimodal. The majority of fibers (85%) had diameters of 0.6-1.0 microm. These results are similar to those obtained for renal nerves of rats with respect to the predominance of unmyelinated fibers. However, the diameter of unmyelinated fibers is larger in rats and the distribution histogram of rat unmyelinated fibers is bimodal, in contrast to the unimodal distribution in mice. The morphological description of the renal nerves in mice provides baseline data for further investigations of the structural basis of altered autonomic reflexes. The results will be useful in analyses of genes that influence the development and structure of sympathetic and sensory innervation of the kidney in genetically manipulated mice.The Anatomical Record 01/2003; 268(4):399-404.

ABSTRACT: Piecemeal degranulation is a unique pattern of cell secretion that consists of a slow release of granule contents from cytoplasmic secretory granules, which leaves empty chambers that do not fuse with each other or with the plasma membrane. To our knowledge, no cell types other than mast cells, basophils, and eosinophils have been reported in the literature to show morphological features of piecemeal degranulation. In the present study we provide evidence for ultrastructural morphologies characteristic of piecemeal degranulation in entero-endocrine cells of the human and murine gastrointestinal epithelia. Human biopsy samples were taken from the mucosa of the distal duodenum, proximal jejunum, and colon in 10 patients undergoing endoscopic examination for malabsorption, diarrhea, and/or abdominal pain. Murine gastrointestinal samples were obtained from 10 adult C57 mice. All specimens were prepared for transmission electron microscopy (TEM) according to standard protocols. Results showed that different types of gastrointestinal entero-endocrine cells, in both humans and mice, were recognizable with ultrastructural features diagnostic for piecemeal degranulation, including specific granule and cytoplasmic changes. In the granules, the content was found to be loosely packed or diminished. Notably, altered granules did not fuse with each other or with the plasma membrane, and were characteristically intermingled with normal, resting granules. At times, the release events transformed the granules into enlarged, empty containers. Numerous entero-endocrine cells presented a rich supply of membrane-bound vesicles (50-200 nm in diameter) that were free in the cytoplasm or attached to granules. This finding of piecemeal degranulation in gastrointestinal entero-endocrine cells suggests that such a secretory model might be a general degranulation pattern in cells involved in paracrine-endocrine secretion.The Anatomical Record 01/2003; 268(4):353-9.

ABSTRACT: Acupuncture meridians traditionally are believed to constitute channels connecting the surface of the body to internal organs. We hypothesize that the network of acupuncture points and meridians can be viewed as a representation of the network formed by interstitial connective tissue. This hypothesis is supported by ultrasound images showing connective tissue cleavage planes at acupuncture points in normal human subjects. To test this hypothesis, we mapped acupuncture points in serial gross anatomical sections through the human arm. We found an 80% correspondence between the sites of acupuncture points and the location of intermuscular or intramuscular connective tissue planes in postmortem tissue sections. We propose that the anatomical relationship of acupuncture points and meridians to connective tissue planes is relevant to acupuncture's mechanism of action and suggests a potentially important integrative role for interstitial connective tissue.The Anatomical Record 01/2003; 269(6):257-65.
