| The pterion is a commonly used anthropologic and neurosurgical landmark defined as the junction of the sphenoid, temporal, parietal and frontal bones. It is commonly classified into four types based on sutural pattern: sphenoparietal, in which the sphenoid and parietal bones are in direct contact; frontotemporal, in which the frontal and temporal bones are in direct contact; stellate, in which all four bones come into contact at a point; and epipteric, in which a small sutural bone is found between the parietal bone and the greater wing of the sphenoid bone. In the present study, 44 Anatolian skulls from two different eras, Byzantine (13th century) and contemporary (20th century), were investigated for morphology and location of the pterion. Sphenoparietal... |

| Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E.fucata, E.insularis, E. cf. ornata, E.rubra, and Eunice sp. was compared using traditional morphometric analysis of 16 measured variables. After removing the size-effect, a Canonical Variates Analysis applied to morphometric variables was able to discriminate all species. In CV1 two major groups of species were discriminated: E.fucata/E.insularis and E. cf. ornata/E.rubra/Eunice sp. CV2 strongly discriminated all species, with E.... |

| Extraocular muscles are important references in strabismus surgery and in placement of intraorbital devices. We analyzed extraocular muscles morphometry and possible anatomical variances of 20 orbits. We report the length, width, and points of insertion of the extraocular muscles. No anatomical variations in length, width and points of insertion were found. With regard to the rectus muscles, it was found that the superior rectus and lateral rectus are the longest muscles and that the width difference between the superior and inferior rectus is greater than that between the medial and lateral rectus and that the point of insertion of the rectus muscles has a variable morphology. The superior oblique muscle was smaller in caliber than the inferior oblique,... |

| Few reports are available about the ichthyofauna of typical semi-arid rivers, although the regional diversity has been constantly threatened by human activities, mainly related to impoundment and construction of dams. The goal of the present work was to evaluate using different methods, the population genetic structure of a characin fish, Astyanax aff. bimaculatus, widespread throughout hydrographic basins of Bahia, Northeastern Brazil. Morphological (meristic and morphometric data), cytogenetic (karyotype and Ag-NOR), and molecular (RAPD and SPAR) analyses were carried out in specimens collected upstream and downstream of Pedra Dam, in the main channel of Contas River (Contas River Basin), and in the Mineiro stream, which belongs to the adjacent Recôncavo... |

| In order to study the detailed morphology of trophoblast cells during human implantation, BeWo cells were cultured as spheroids in suspension culture. These cultures were then processed for light and electron microscopical examination. The present study showed that the BeWo spheroids consist of two cell types which are cytotrophoblast-like and syncytiotrophoblast-like. The cells with larger nuclear diameter made up only about 1% of the cell population and appear to be those of syncytiotrophoblast. Therefore the predominant cell type of the BeWo spheroids appeared to be relatively undifferentiated and cytotrophoblast-like. About 10% of the BeWo cells in the present study were mitotic, indicating a highly proliferative population. Total cell number increased... |

| It was aimed that the morphometric development of calcaneal tendon and the structures building it up in human fetuses during the fetal period be anatomically studied and that its clinical importance be evaluated. The study comprised a total of 102 fetus legs (51 human fetuses: 26 male and 25 female) whose ages varied between 15-40 gestational week, without external pathology or anomaly. The fetuses were divided in groups according to gestational weeks, trimesters and months. In the wake of the general external measurements of fetuses, leg dissection was performed. Afterwards, the morphometric parameters of gastrocnemius muscle, soleus muscle and calcaneal tendon were measured. The averages and the standard deviations of the measured parameters were... |

| The acromion is classically described as one of the three scapular processes. Its antero-inferior aspect has been identified as the prime region of rotator cuff pathology. The purpose of this study was to determine the morphologic state of the acromion and the relative subacromial architecture within a South African population. The sample series comprised the morphological observation of one hundred and eighty-two scapulae specimens (n= 182). The classification scheme as stated by Bigliani et al. (1986) was employed. The morphometric architecture of the subacromial space was also investigated (n= 120). (a) Acromial Type: (i) Type I (flat inferior surface) 34.6%; (ii) Type II (curved inferior surface) 51.1%; (iii) Type III (hooked inferior surface) 14%. (b)... |

| The aim of this study was to accurately measure acromial morphology in order to describe the anatomical patterns of its subtypes and to conduct a survey of the literature regarding the relationships between morphological subtypes and their related diseases. We photographed scapulae from the Institute of Anatomy, University Severino Sombra, and analyzed the images using Image-J Software®. The average acromial angle was 139.23° ± 2.781, with no significant difference between the right and left sides. There was a positive correlation between the acromial angle and the angle of the spine of the scapula. The correlation mentioned above plays an important role in disorders of the shoulder-particularly impingement syndrome-which reinforces the importance of... |

| The aim of this study was to investigate the effect of boar age on quality traits and fertility of liquid-stored semen. Boars were allocated into 3 age groups: 7-10 months (young), 18-33 months (mature), 51-61 months (old). Ejaculates of > 200x10(6) sperm/ml and 85% total motile sperm were extended to 30x10(6) sperm/ml, stored at 17-18 °C and used within 12-24 h for artificial insemination (AI) of 2062 multiparous sows. After 24 h of storage, aliquots of diluted semen were assessed for sperm progressive motility (SPM), incidence of sperm chromatin instability (SCI), proportion of live morphologically normal sperm (LMNS) and head morphometry of LMNS. The results showed that young boars had higher percentages of SCI and lower proportions of LMNS than... |

| The jugular foramina (JF) are bilateral openings situated between the lateral part of the occipital bone and the petrous part of the temporal bones in the human skull. It is a bony canal transmitting neurovascular structures from the posterior cranial fossa through the base of the skull to the carotid space. Since the JF depicts variations in shape, size, height and volume between different racial and gender groups, along with distinctive differences in laterality from its intracranial to extracranial openings, knowledge of the JF may be necessary to understand intracranial pathologies. Therefore, the purpose of this study was to evaluate the morphometric measurements of the jugular foramen. Various morphometric parameters of the JF and its relation to... |

| The mandibular condyle is the rounded protuberance that articulates with the mandibular fossa to form the temporomandibular joint (TMJ). The shape of the mandibular condyle may be classified according to five basic shapes viz. flattened, convex, angled, rounded and concave. Previous research indicated that variation in the shape and size of the mandibular condyle, exists and that population-specific differences may also occur. This study aimed to document the shapes and size of the mandibular condyle and determine their relationship with regard to sex, age and race (if any). The morphometric and morphological parameters of the mandibular condyle were measured and assessed in 54 dry mandible specimens (n= 108). The Wedel et al. (1978) classification scheme... |

| Humerus is the longest and thickest bone of the upper limb. As a long bone, it has two epiphysis and diaphysis. In this study, we aimed to conduct morphometric measurements belonging to human humerus. This study was conducted on 60 humerus (28 right, 32 left) in collections of Necmettin Erbakan University Meram Medicine Faculty Anatomy Laboratory. Digital calipers, osteometric board and precision scales for humerus bone measurements were used. Measurements were classified as measurements of diaphysis and proximal and distal epiphysis of humerus. Each bone weight was determined. Also nutrient foramen number and localization was determined. In this study, it was determined that mean right humerus length 30.41±1.73 mm, mean left humerus length 30.04±2.39 mm.... |
