Vertebral artery (VA), the main element of the posterior brain circulation, has many anatomical variations which generally were widely investigated. However, available data vary in wide ranges, reflecting very different sample sizes, lack of data about left-right or sex differences, and about possible ethnic, regionally specific or genetic differences. Certain new findings suggest possible involvement of some environmental factors in VA variations. Accurate anatomical data about VA variations in different regions of the world, including Balkans countries, are still lacking...

BACKGROUND: Medical education in Ottoman-Turkish medicine was shaped by the influence of Claudius Galenus (c.130-c.210) and Ibn-i Sina (c.980-c.1037). These teachings were performed in madrasahs until the beginning of the 19th century period. Within the scope of master-apprentice relationship, medical training was also given in private clinics. As a result of religious and social pressures on scientific studies human cadavers were never used because they were considered sacred. For centuries, all books were handwritten during the Ottoman Empire until the first printing press was established in Istanbul during 1726...

The plantaris muscle is characterized by morphological variability, both for origin and insertion, and may sometimes be absent. Its strength allows the ligament to be used for reconstruction of other tendons and ligaments. This report presents the rare placements and course of the plantaris muscle in relation to the neurovascular bundle. In this case, the hypertrophy of this muscle might cause pressure on the tibial nerve and produce symptoms similar to sciatica.

Triticeous cartilage is a small cartilaginous component of the laryngeal skeleton. This cartilage, located in posterior end of the thyrohyoid ligament, presents in different shapes. Radiological studies indicate clinical and anatomical importance of the triticeous cartilage but these studies have limited information due to inadequate inspection method. Computed tomographic angiography is able to evaluate the triticeous cartilage with using 3 dimensional images in more detail. The aim of this study is describing prevalence and morphological properties of the triticeous cartilage...

The mandibular canal (MC) originates in the mandibular foramen and runs bilaterally through the mandibular ramus and body, ending in the mental foramen. One of the most common anatomical variations is bifid MC, the configurations of which have been classified into four categories and sub-categories. The prevalence of these variations depends on the imaging method used. Studies carried out in panoramic X-rays and Cone Beam Computed Tomography (CBCT) show prevalences varying between 1% and 20%. In this case report we present the finding of a bilateral bifid MC by CBCT examination; we describe its location and morphological characteristics...

A 56 year old nulliparous female Asian elephant (Elephas maximus) living at the zoological garden of Naples (Italy), with a clinical history of recurrent colic, was found in agonal state and humane euthanasia was elected. At necropsy the uterine body was moderately increased in size and the lumen was reduced due to a poorly demarcated and infiltrative neoplasm. Furthermore, multiple, whitish, firm nodules were present in both lungs. Histological examination of the uterine mass revealed epithelial cells arranged in tubular or solid pattern infiltrating the endometrium and the muscular layer...

BACKGROUND: As far as our literature searches showed us, morphological characteristics of cranium such as sutures, sutural bones and fontanelles had been examined from the skulls in the museums and dry specimens until now. As a modern method, 3D virtual remodeling of cranial bones by using MDCT-CTA can display in vivo morphological characteristics. In our study, we aimed to determine the presence and incidence of these morphological characteristics that can be clinically significant in our population, by using radiologic methods...

Traumatic brain injury (TBI) is in part associated with the disruption of the blood-brain barrier. In this study, we analyzed the histopathological changes in E-cadherin and VEGF expression after traumatic brain injury in rats. The rats were divided into 2 groups as the control and the trauma groups. Sprague-Dawley rats were subjected to traumatic brain injury with a weight-drop device using 300 g⁻¹ m weight-height impact. After 5 days of traumatic brain injury, blood samples were taken under ketamine hydroxide anesthesia and biochemical analyzes were performed...

The existence of posterior epidural ligaments (PEL) has been established in the lumbar region, but they have hitherto not been shown to exist in the thoracic vertebral column. Their identification is of clinical significance in respect to incidental durotomy and the circulation of cerebro-spinal fluid. Fourteen thoracic spine sections were dissected by cutting through the intervertebral disc and separating the ligamentum flavum from the vertebra above. The dural sheath was gently retracted anteriorly to identify macroscopic connections between the ligamentum flavum and the dura...

Variations in the relationship of the retromandibular vein to the facial nerve have been widely reported due to their relevance for surgical approaches in parotid, osteotomy and mandibular condyle surgery. In the context of the retromandibular retroparotid approach, remaining deep to the retromandibular vein is advised to decrease the likelihood of encountering the facial nerve during mandibular condyle surgery. In the present report, an unusual variant of the superficial temporal vein lying superficial to the facial nerve is described...
