Objective: The cranial base harbours numerous foramina, and the anatomical properties of foramina are crucial in clinical interventions. purpose current study is to evaluate possible asymmetries regarding middle posterior fossae using 3D reconstructions high-resolution computed tomography (CT) images. Patients Methods: High-resolution CT images 253 female 287 male adult patients were used study...

The metacarpus of Indian Blackbuck comprised of two metacarpal bones. The large metacarpal bone consisted of fused III and IV metacarpals. The shaft of the metacarpus presented two surfaces and two borders. The dorsal surface was smooth and semi-cylindrical in outline. The palmar surface was flat in outline and it presented a deep longitudinal groove which possessed similar foramina. These fora...

Four hundred and eighty foramina transversaria in dry cervical vertebrae of 36 spines and in a number of dissections were studied and classified according to size, shape, and direction of their main diameter. A coefficient of roundness was then elaborated. The variations of foramina appear to follow a pattern at various vertebral levels. The possible factors (in addition to the embryological on...

NMR analyses of striatol produced by suspension-cultured cells of liverwort, Ptycanthus striatus, in the presence of [2-(13)C]- and [4,4-(2)H2]-MVAs confirmed proton-catalyzed cyclization between the distal and central double bonds in FPP and a concerted series of 1,2-migrations of hydrogen and a methyl group, with subsequent elimination of a proton.

study medicine in 1536 and supported himself by lecturing on mathematics, geography and astronomy. In Paris, his teachers included Sylvius and Andermach, who hailed him with Andrea Vesalius as his most able assistant in dissections There he stepped over the line that Christian doctrine had drown between acceptable areas of astrology, and forbidden zone of judicial astrology (left for God-essent...

Introduction: Main source of nutrition to long bone during growth and ossification is nutrient artery. Nutrient canal opens as foramen on the surface shaft which conducts artery peripheral nerves bones. provides more than 60-70% blood supply bone, 30- 40% through periosteal, metaphyseal epiphyseal vessels. Aim: To determine number foramina, its position shaft, size direction foramina either tow...

In the primate visual system, area V4 is located in the ventral pathway and is traditionally thought to be involved in processing color and form information. However, little is known about its functional role in processing motion information. Using intrinsic signal optical imaging over large fields of view in V1, V2, and V4, we mapped the direction of motion responses in anesthetized macaques. ...

The term stenosis means a narrowing of the calibre of an orifice or a tube. It causes a decreased flow of fluids or gasses within the tube or compression of its solid contents (Verbiest 1976). In the case of the spinal canal, the term indicates a pathological condition causing compression of the contents of the canal, particularly the neural structures. If compression does not occur, the canal ...

In the present study, periapical radiographs were analyzed to investigate the number of canals of the buccal root of maxillary 1st premolars with longitudinal sulcus, and compare the number of apical foramina observed on the radiographs to that revealed by scanning electron microscopy (SEM). Thirty-nine human maxillary 1st premolars had their crowns and palatal roots removed and the root canals...

Toothed mysticetes of the family Aetiocetidae from Oligocene rocks of the North Pacific play a key role in interpretations of cetacean evolution because they are transitional in grade between dorudontine archaeocetes and edentulous mysticetes. The holotype skull of Aetiocetus weltoni from the late Oligocene (28–24 Ma) of Oregon, USA, has been further prepared, revealing additional morphological...
