En la vértebra atlas, los puentes posteriores, los puentes laterales y los túneles postero-laterales son las protrusiones óseas que pueden causar presión externa en la arteria vertebral cuando pasa  del foramen transverso de la vértebra cervical al foramen magnum del cráneo. Ejemplares que muestran dichas protrusiones fueron clasificadas según tengan puentes del atlas completos o incompletos que pueden predisponer a la insuficiencia vertebrobasilar y al síndrome cervicogénico especialmente durante los movimientos de cuello. El objetivo del estudio es saber la incidencia, ontogenia y filogenia de los puentes del atlas junto con las implicaciones clínicas. Este canal de la arteria vertebral del atlas y la morfología de los puentes fueron estudiados en un total de 60 (120 lados) vértebras atlas humanas completas y secas obtenidas de la colección de esqueletos del Departamento de Anatomía del Government Medical College de Amritsar en Punjab. La incidencia de la impresión de la arteria vertebral (44), la impresión profunda de la arteria vertebral (42) era 71,66%, el puente parcial fue 13,33% y el puente lateral parcial fue 3,33% en el lado derecho y 5% en lado izquierdo. También se observaron doce anillos completos y un túnel 1.66% postero-lateral. La ocurrencia de estos puentes óseos abrazando la arteria vertebral es de suma importancia clínica, pueden causar efecto de comprensión en la arteria vertebral durante la rotación extrema de la cabeza y movimientos de cuello manifestándose en mareos, desmayos, diplopía temporal, vértigo y desórdenes neurológicos. El conocimiento de esta variación es importante para médicos, otorrinolaringólogos, neurólogos y ortopedistas que en la práctica diaria están en contacto con estas enfermedades de la columna vertebral y sus consecuencias.  In atlas vertebrae, the posterior bridges, lateral bridges and postero-lateral tunnels are the bony outgrowths which may cause external pressure on the vertebral artery when it passes from foramen transversarium of the cervical vertebra to foramen magnum of the skull. Specimens exhibiting such outgrowths were classified as having incomplete or complete atlas bridges that may predispose to vertebro-basilar insufficiency and cervicogenic syndrome especially in neck movements. The objective of the study is to know the incidence, ontogeny and phylogeny of atlas bridges along with its clinical implications. The groove of the vertebral artery of the atlas and the morphology of the bridges were studied in a total of 60 (120 sides) complete and dry human atlas vertebrae obtained from the skeletal collection of Department of Anatomy,GovernmentMedicalCollege,Amritsar,Punjab.  The incidence of impression of vertebral artery (44), deep impression of vertebral artery (42) was 71.66%, Partial ponticuli were 13.33% and Partial lateral ponticuli were 3.33% on right side and 5% on left side. Twelve complete rings and one 1.66% postero-latetal tunnel was also observed. Occurrence of these bony bridges embracing the vertebral artery is of great clinical importance, may cause compression effect on the vertebral artery during extreme rotation of head and neck movements presenting with dizziness, fainting, transient diplopia, vertigo and neurological disturbances. The knowledge of this variation is important for physicians, otolaryngologists, neurologists and orthopaedicians who in every day practice are in contact with the diseases of spine and their consequences.

Abstract Introduction: Meckel's diverticulum or ileal diverticulum is one of the common congenital anomalies of the digestive system. It may not cause any problems in many, but may form serious life threatening complications in a few. Materials and Methods: We conducted a histo-morphological study of a giant Meckel's diverticulum found during cadaveric dissections of a South Indian adult male cadaver. The diverticulum was 7.5 cm long and had a circumference of 1.5 cm. Results: Gross anatomical and histological observations revealed healthy nature of the diverticulum without any inflammation. However, the mucosa had gastric type of glands with plenty of parietal cells. This incidence of Meckel's diverticulum was noted in only one cadaver among more than 100 cadavers dissected in the past twenty years. Conclusion: Knowledge of its morphological features may be very useful to surgeons, radiologists and gastroenterologists. We discuss the clinical importance of the diverticulum and review the relevant literature in this manuscript.

Introduction: The axis is the second cervical vertebra and differs from the others by presenting particular anatomical landmarks. Morphological variations of the axis in different populations have clinical importance, since the lack of anatomical reference may compromise surgical procedures in this region. Objective: To analyze the morphometry of axis vertebra in northeastern Brazil. Methodology: Data collection was performed at the Federal University of Paraiba. Fifty-eight axis were used. Damaged or infantile vertebrae were excluded.Morphometric analysis was performed using a digital caliper and the data were statistically analyzed. Results were considered significant when p<0.05. Results: The width of the pars interarticulares was 9.25±1.68mm and the height was 7.37±1.87mm. The height of the dens of the axis in an anterior view was 16.29±1.82mm and the width was 9.41±0.86mm. The width of the articular face of the dens was 8.27±0.88mm. The anteroposterior length of the vertebral body was 15.29±2.02mm, the width was 16.79±1.68mm, and the height in anterior view was 19.96±2.48mm. The mean height of the vertebral lamina was 10.89±1.64mm and the anteroposterior length was 20.33±2.13mm. Significant difference was observed between right and left sides of anteroposterior length (p=0.012). Conclusion: Axis morphometry was shown for the first time in a specific population from northeastern Brazil. Morphological differences were observed in the present study and differ from others in the literature. These data may serve as guidance for professionals who will perform any procedures in this region, highlighting the importance of anatomical knowledge and its variations.

AbstractThe cervical vertebrae presents foramen transversaria in each transverse process. In all but the seventh cervical vertebra, the foramen normally transmits vertebral artery and vein and a branch from the cervicothoracic ganglion.140 cervical vertebrae were studied. Variations were noticed in the number of foramen transversarium unilaterally and bilaterally. Variations in foramen transversarium may indicate the variation in course of vertebral arteries

The coleorhiza is a nonvascular sheath that encloses the embryonic radicle in Poaceae, and is generally the first tissue to emerge during germination. Delicate hairlike extensions develop from some coleorhiza cells prior to radicle emergence. Similar to root hairs, coleorhiza hairs are extremely sensitive to desiccation and are damaged by exposure to negative water potentials. The coleorhiza of Lolium perenne is somewhat spherical when first visible, after which a knob forms at a right angle to the caryopsis due to inner pressure from the elongating radicle. This knob increases in length until the radicle finally punctures the coleorhiza. Standard fixation procedures cause severe desiccation of coleorhiza cells and hairs, making morphological study of the coleorhiza difficult. This study was conducted to determine a more successful process for coleorhiza preservation.

Abstract The modern clinician is a research consumer. Rehabilitation of oropharyngeal impairments, and prevention of the adverse outcomes of dysphagia, requires the clinician to select interventions for which evidence of a reasonable likelihood of a successful, important outcome exists. The purpose of this paper is to provide strategies for evaluation of published research regarding treatment of oropharyngeal dysphagia. This article utilizes tutorial and examples to inform and educate practitioners in methods of appraising published research. It provides and encourages the use of methods of efficiently evaluating the validity and clinical importance of published research. Additionally, it discusses the importance of the ethical obligation we, as practitioners, have to use evidence-based treatment selection methods and measurement of patient performance during therapy. The reader is provided with tactics for evaluating treatment studies to establish a study's validity and, thereby, objectively select interventions. The importance of avoiding subjective or unsubstantiated claims and using objective methods of generating empirical clinical evidence is emphasized. The ability to evaluate the quality of research provides clinicians with objective intervention selection as an important, essential component of evidence-based clinical practice.
