There is a peculiarity in the articulation of the two parietal bones with the frontal bone at the top of the skull. The anterior border of the parietal bone is deeply serrated and is bevelled at the expense of the outer surface above and of the inner below. The border of the vertical portion of the frontal bone is thick, strongly serrated, bevelled at the expense of the internal table above, wh...

the aim of this study was to determine the anatomical features of the auditory ossicles in rat. twenty temporal bones from 10 adult rats were used. the features of the ossicles were assessed with an ocular micrometer and photographed by a stereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. temporal bone in rat was similar to other animals consists of ...

INTRODUCTION Mouse models are used frequently to study effects of bone diseases and genetic determinates of bone strength. Murine bones have an intracortical band of woven bone that is not present in human bones. This band is not obvious under brightfield imaging and not typically analyzed. Due to the band's morphology and location it has been theorized to be remnant bone from early in life. Fu...

AbstractBackground: Given the high relapse rate of disease in children with steroid dependent nephrotic syndrome and the osteoporotic effect of long periods of steroid therapy, this survey was performed to find the bone mineral status of these patients. Methods: Bone mineral density and content (BMD and BMC) were measured using Dual energy X-ray absorptiometry in 37 nephrotic children, six girl...

The head consists of the skull, face, scalp, teeth, brain, cranial nerves, meninges, special sense organs, and other structures such as blood vessels, lymphatics, and fat. It is also the site where food is ingested and air is inspired and expired (Fig. 101; Fig. 102). Diseases of important structures in the head form the bases of many medical, dental, and surgical specialties dentistry, maxillo...

Conducted biomineralogical studies indicate piezoelectric properties of apatite, which is one of the major components of bone. This publication presents hypothetical correlations between piezoelectric properties of bone apatite and the accompanying electromagnetic phenomena in bones and their environment. It notes the correlations between electrical properties of bones and changes in the electr...

A 10-year-old boy was referred to us for evaluation of FUO accompanied with bone pain in both calves. Three hours after intravenous injection of 13 mCi of 99mTc-MDP, whole body scan in multiple spot views was performed. The scan showed symmetrical areas of diffusely increased tracer uptake in multiple long bones. Histopathologic evaluation confirmed osteosclrosis and fibrotic changes...

UNLABELLED To examine the link between bone material properties and skeletal fragility, we analyzed the mechanical, histological, biochemical, and spectroscopic properties of bones from a murine model of skeletal fragility (SAMP6). Intact bones from SAMP6 mice are weak and brittle compared with SAMR1 controls, a defect attributed to reduced strength of the bone matrix. The matrix weakness is at...

Many of the sclerosing bone dystrophies fall within the classification employed by Fairbank (1951). However, patients occasionally present features suggesting a possible relationship between osteopoikilosis (spotted bones), osteopathia striata (striated bones, Voorhoeve’s disease), melorheostosis (running wax bones) and osteopetrosis (dense or marble bones). Areas of dense bone arranged in diff...
