primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

The maxillofacial region of patients with facial asymmetry is deformed not only in the mandible but also maxilla, suggesting that head may be deformed. Therefore, this study, skeletally originated mandibular prognathism was evaluated relation to cranial morphology. morphology who visited Chiba Dental Center Tokyo College and were diagnosed skeletal (asymmetry group: ANB 0° or less; Menton devia...

The extant anuran fauna of Madagascar is exceptionally rich and almost completely endemic. In recent years, many new species have been described and understanding of the history and relationships of this fauna has been greatly advanced by molecular studies, but very little is known of the fossil history of frogs on the island. Beelzebufo ampinga, the first named pre-Holocene frog from Madagasca...

Quantification of anatomical and physiological characteristics of the function of a musculoskeletal system may yield a detailed understanding of how the organizational levels of morphology, biomechanics, kinematics, and muscle activity patterns (MAPs) influence behavioral diversity. Using separate analyses of these organizational levels in representative study taxa, we sought patterns of congru...

BACKGROUND Pachycephalosaurs were bipedal herbivorous dinosaurs with bony domes on their heads, suggestive of head-butting as seen in bighorn sheep and musk oxen. Previous biomechanical studies indicate potential for pachycephalosaur head-butting, but bone histology appears to contradict the behavior in young and old individuals. Comparing pachycephalosaurs with fighting artiodactyls tests for ...

Cranial base morphology differs among hominoids in ways that are usually attributed to some combination of an enlarged brain, retracted face and upright locomotion in humans. The human foramen magnum is anteriorly inclined and, with the occipital condyles, is forwardly located on a broad, short and flexed basicranium; the petrous elements are coronally rotated; the glenoid region is topographic...

The form, geometry and epithelial morphology of the extrapulmonary primary bronchi (EPPB) of the domestic fowl (Gallus gallus var. domesticus) and the rock dove (Columba livia) were studied microscopically and by three-dimensional computer reconstruction to determine the structural features that may be involved in the rectification of the inspired air past the openings of the medioventral secon...

Developmental variations in the cranial vault arise during early ontogenesis due to premature or delayed suture closure, non-union between normal ossification centers, and emergence of additional centers. These cause abnormal calvarial partition are often associated with modifications overall configuration. This study aims evaluate impact metopic persistence development supernumerary bones occi...

in the present study, eight specimens of sheep (>1 year) of both sexes were dissected to provide a comprehensive description of the weight, allocation and nerve branches of the cranial cervical ganglion. the cranial cervical ganglion was found beneath the mandibular salivary gland. it was located ventromedial to tympanic bulla and ventrally to atlantic fossa. in three out of eight animals it wa...
