| Deer and sheep are used as spinal animal models in clinical and basic research. In this paper, the anatomical morphology, curvature, and morphology index parameters were investigated to assess the feasibility of using deer and sheep as animal models of the human spine. Fresh adult male sheep, deer, and human spine specimens (n = 10 each) were screened and subjected to morphological analyses. The statistical software package SPSS (version 17.0) was used to analyze the statistical similarity and variability among the 3 species. Deer displayed good similarity to human in terms of the vertebral transverse diameter, radius vector, spinal canal transverse diameter, radius vector, and vertebral upper and lower endplate curvature radii. Sheep displayed good... |

| Organophosphoric (OP) agropesticidas are amply used to increase food production. However, it has been verified that they induce alterations at testicular level related to the diminution of fertility in humans as in animals. On the other hand, different studies have been made to develop chemical or natural compounds that can induce an antagonistic effect to OP. In previous studies an extract from a plant, from the Peruvian Andes (Maca) has been recognized by its stimulating action on spermatogenesis. In the present study the effects of both external agents were evaluated on testicular sections of testis of adult male mice on a population of 52 mice CF1, divided at random in 4 groups (Control, Malathion, Maca, Malathion-Maca), with sacrifice intervals of... |

| Most of the neotropical bats reproduce in a seasonal fashion. The purpose of this study was to assess changes in testicular tissue by morphometry, in Tadarida brasiliensis bat, in a south urban zone of Mexico City during summer, autumn, and winter. Three sample collections (February, June, and September) from T. brasiliensis were carried out (n=6). Testicle fragments were obtained for histological studies. Diameter of the seminiferous tubules and interstitial space were measured, cellular populations were identified and counted. June samples showed smaller diameter of seminiferous tubules and larger interstitial space between tubules; also there were less number of germinal epithelium cells and spermatids were absent. Tissues from September and February... |

| The contents of soybean can modify the structure of the reproductive system, especially, when consumed for prolonged periods. In this study, we evaluated the effects of the consumption of transgenic soybean on rat penis morphology after prolonged use. Wistar rats (n = 30) were divided into three groups according to diet: Transgenic Soybean (TS) group, Organic Soybean (OS) group and Control (C) group. After 455 days of intake, the rats were sacrificed and the penises were excised and fixed in formalin for subsequent histological processing. The samples were stained with hematoxylin and eosin, Weigerts resorcin-fuchsin stain, and picrosirius red with polarization. The images were scanned for the histomorphometric analyses of the corpora cavernosa, corpus... |

| A detailed knowledge of the anatomic morphometry of infraorbital groove, canal and foramen was necessary for a surgeon while performing maxillofacial surgery and regional block anaesthesia. Modern surgical procedures as well as anaesthesia require more precise understanding of the surrounding anatomy. The aim of the study was to establish morphometrically the infraorbital foramen size and location in human foetuses, the area where this information was scanty. Sixty maxillae were dissected out from thirty human foetuses. The latter were divided into five groups on the basis of age i.e. groups I(<17 weeks IUL),II (17-20 weeks IUL), III (21-25 weeks IUL),IV (26-30 weeks IUL) and V (>30 weeks IUL). Four parameters including transverse diameter and... |

| The knowledge of dental morphometry, especially of its radicular portion, is of great importance for certain dental specialties, such as, endodonty. Regarding the permanent lower anterior teeth we know that its morphology and root length, are variable. The aim of this study was to analyze the average length of the dental roots of permanent lower anterior teethin Brazilian individuals. The average root length obtained in this study for the lower central incisors was 13.07 mm; to lower canines the value found was 15.81 mm; the average value for the radicular portion of lower lateral incisors was 13.08 mm. We conclude that the mean value for the length of the radicular portion of permanent lower central incisors is similar to that found for permanent lower... |

| The caroticoclinoid foramen is an inconstant structure, formed by the union of the anterior and middle clinoid processes. The aim of this study was to perform an incidence and morphometry of the caroticoclinoid foramen in Brazilian human skulls and discuss its clinical implications. Eighty dry human skulls with sex distinction were used, and 3 groups of incidence were determined: General, sex, and sides. The morphometry was performed using a manual caliper and the major diameter of the foramina was measured; the values were also divided in general, according to sex and sides. The incidence of skulls with at least one foramen was 8.5%. According to the sides, 8.5% of the skulls showed foramen on the right side and 2.5% on the left. We found 2.5% of the... |

| The anterior clinoid process (ACP) is proximal to vital structures, such as the optic nerve, internal carotid artery and ophthalmic artery; therefore, study of its anatomy is important in guiding and defining surgery. We studied the anatomical structure of the ACP, including the angle formed by the apex of the ACP triangle, and its orientation, to provide information for easier and safer surgery. The measurement was performed on the axial planes of 242 cranial computerized tomography (CT) scans and 27 adult Turkish skulls of both sexes. The length of the ACP, width of the ACP at its base, the angle formed by the apical angle of the ACP triangle and the orientation of the ACP defined according to the sagittal midline were examined. In the Turkish skulls,... |

| Anterior access to the L1-L5 vertebrae and disc spaces can be technically challenging, frequently requiring the use of an approach to a surgeon for an adequate exposure. The technique is used for lesion excision, corpectomy, vertebral body reconstruction with cages, realignment, and/or plating or screwing. For a successful anterior approach and a suitable instrumental design via screw, adequate morphometric knowledge about body of lumbar vertebrae and disc spaces and standardized volumetric data are also required for neurosurgeons. We aimed morphometric and volumetric evaluation of lumbar bodies and discs to contribute to a safe anterior approach during surgery. We evaluated vertebral body and disc morphometry using stereology in right-handed 25 adult... |

| 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... |

| The musculotendinous hood of the rotator cuff muscle complex is formed by four tendons which thicken and merge with the underlying glenohumeral capsule as they insert onto the respective regions of the humeral head. This insertional anatomy has been reported to exhibit several pathological patterns which serve as the basis for the operative repair of cuff tears. Since previous literature concentrated on macro-evaluations of tears specific to the supraspinatus tendon, the present study aimed to investigate the macro- morphological and morphometric parameters of all four rotator cuff tendons. Observation of the insertion site configurations and computation of the relative tendon morphometry were performed once the glenohumeral region in forty adult cadaveric... |

| The tibia is the medial long bone of the leg and is characterized by a shaft and two expanded extremities. Despite the recent advent of tibial bone graft harvesting, the tibia has also been confirmed to be of great forensic significance. As this appears to be the only tibial dry bone study done in Southern Africa, this study aimed to investigate morphological and morphometric parameters that are of clinical and anthropometric importance. Morphological and morphometric examination of 302 adult tibial bone specimens of Black South Africans obtained from the osteological bank of the Discipline of Clinical Anatomy at the University of KwaZulu-Natal was performed. The sample consisted of 168 males and 134 females with an age range of 15 to 87 years old. The... |

| 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... |
