The microanatomy of the alveolar duct system.
Observations made on wet and dry slices of inflated human lungs taken at necropsy have been used to give a more complete account of the alveolar duct system, the basic respiratory structure. This includes consideration of the central spiral alveolar duct fibre, which is thought to consist of elastic and collagen, the spiral arrangement of alveoli and the special nature of the terminal alveolus,...
متن کاملVariations in microanatomy of the human cochlea
The human cochlea shows considerable interindividual variability in size and morphology. In order to develop atraumatic cochlear implant (CI) electrodes, high-precision details of the variability of human anatomy are required. Sixteen human temporal bones were cut around the cochlea in blocks of approximately 3.5 × 3.5 cm. The bones were scanned by using a Skyscan 1173 micro-computed tomography...
متن کاملThe Ventral Photoreceptor Cells of Limulus I. The microanatomy
The ventral photoreceptor cells of Limulus polyphernus resemble the retinular cells of the lateral eyes both in electrical behavior and in morphology. Because of the great size of the ventral photoreceptor cells they are easy to impale with glass capillary micropipettes. Their location along the length of the ventral eye nerve makes them easy to dissect out and fix for electron microscopy. Each...
متن کاملMicroanatomy of Early Devonian book lungs.
The book lungs of an exceptionally preserved fossil arachnid (Trigonotarbida) from the Early Devonian (approx. 410 Myr ago) Rhynie cherts of Scotland were studied using a non-destructive imaging technique. Our three-dimensional modelling of fine structures, based on assembling successive images made at different focal planes through the translucent chert matrix, revealed for the first time foss...
متن کاملMicroanatomy of the human liver-exploring the hidden interfaces.
The functional unit of an organ may be defined as the smallest, structurally distinct, ‘‘self-sufficient’’ unit that can independently subserve all known functions of that organ. The nephron is exemplary of such a concept, for it is both a well-defined functional and structural unit. A similar hepatic unit that can reconcile the dual vascular supply and the dual outflow tracts (vascular and bil...
