The tuberculum sphenoidalis (TS) is an anatomical structure of variable form located at the anterior extremity of the infratemporal crest of the greater wing of the sphenoid. The object of this study was to analyse the morphology and frequency of the TS in macerated skulls. We examined 304 macerated skulls belonging to individuals of both sexes, Amerindian and Caucasian. The TS were classified ...

It was nearly a centenary ago that severe ankle sprain was recognized as an injury of the ankle ligament(s). With the recent technological advances and tools in imaging and surgical procedures, the management of ankle sprains - including subtalar injuries - has drastically improved. The repair or reconstruction of ankle ligaments is getting more anatomical and less invasive than previously. Mor...

Analysis of deformations in terms of principal directions appears well suited for biological tissues that present an underlying anatomical structure of fiber arrangement. We applied this concept here to study deformation of the beating heart in vivo analyzing 30 subjects that underwent accurate three-dimensional echocardiographic recording of the left ventricle. Results show that strain develop...

BACKGROUND Many classification methods have been proposed based on magnetic resonance images. Most methods rely on measures such as volume, the cerebral cortical thickness and grey matter density. These measures are susceptible to the performance of registration and limited in representation of anatomical structure. This paper proposes a two-stage local feature fusion method, in which deformabl...

This review focuses on the role of long-range connectivity as one element of brain structure that is of key importance for the functional-anatomical organization of the cortex. In this context, we discuss the putative guiding principles for mapping brain function and structure onto the cortical surface. Such mappings reveal a high degree of functional-anatomical segregation. Given that brain re...

OBJECTIVE The purpose of this study is to provide an optimized method to reconstruct the structure of the upper airway (UA) based on magnetic resonance imaging (MRI) that can faithfully show the anatomical structure with a smooth surface without artificial modifications. METHODS MRI was performed on the head and neck of a healthy young male participant in the axial, coronal and sagittal plane...

The cownose ray, Rhinoptera bonasus, is currently listed as vulnerable and threatened species by the IUCN Red List due to overfishing bycatch in worldwide resulted declines of steep population 30-49% only 43 years. We aimed present suitable dissection methods for a necropsy ray with large, rhomboid-shaped wing-like pectoral disc compressed dorsoventrally using specific approach observe external...
