| Las condiciones ambientales asociadas a gradientes altitudinales inducen modificaciones de las características morfo-anatómicas de las especies que ahí se encuentran. Las variaciones morfo-anatómicas en regiones intertropicales han sido poco documentadas. Se espera que los patrones relacionados con estos gradientes altitudinales serán similares a aquellos registrados en regiones fuera de la zona intertropical. Se estudiaron seis especies (Acaena elongata, Alchemilla procumbens, Geranium seemannii, Lupinus montanus, Ribes ciliatum y Symphoricarpos microphyllus) que se distribuyen en el gradiente altitudinal del Cerro Tláloc, Estado de México con el objetivo de reconocer y evaluar las modificaciones morfo-anatómicas asociadas al gradiente. Se recolectaron... |

| Liver is the largest gland in the body and rarely shows variations in its lobes and fissures. We studied 55 Formalin-fixed livers for occurrence of abnormal shape, lobes, fissures and position of gall bladder. In 60% of cases the liver was normal. 40% livers showed one or the other variations. Additional lobes were found in 9.09% of cases. Additional fissure was found in 1.81% of cases. Presence of dumbbell shaped caudate lobe and presence of large papillary process was noted in 1.81% cases each. In 1.81% cases the fissure for ligamentum teres was absent or situated on the anterior surface of the liver. In 1.81% of cases each the liver was either extremely long or extremely flat. In 18.18% of the cases, the gall bladder was short and its fundus did not... |

| The variations of the hyoid bone has a great significance for surgical procedures of neck region, and in forensic medicine for evidence of strangulation or hanging, which causes fractures. The aim of this study was to investigate the morphological and morphometrical variations of the hyoid bone in Anatolian population. A total of 60 adult larynx specimens (46 male, 14 female) were dissected to identify morphological and morphometrical variations of hyoid. The infrahyoid muscles and thyrohyoid membrane were cut and ligamentous structures of bone were removed. The variations of shape of the hyoid were classified into six types: A (U-shaped) hyoid bone observed in 31.7 % (19 bones), a horseshoe-H-type in 10 % (6 bones), a B-type hyoid in 31.7 % (19 bones), a... |

| Ansa cervicalis is a loop of nerves found in the anterior wall of the carotid sheath in the carotid triangle of neck innervating infrahyoid muscles. Its superior root has fibres from the first cervical nerve that leaves the hypoglossal nerve and joins the inferior root formed by the branches from the second and third cervical nerves. The two roots join to form ansa cervicalis. The ansa cervicalis nerve formation is relatively complex, as its course and location along the great vessels of the neck vary. In the present case on the left side of an adult male cadaver the inferior root was absent and the contributions from C2 and C3 were joining independently with the superior root of ansa to form ansa cervicalis. However no such variation was found in the ansa... |

| A thorough knowledge of the variations in the patterns of muscle insertion and the consequent neurovascular entrapment due to them is important for orthopedic and plastic surgeons. During routine dissection, we encountered a unique occurrence of an accessory brachialis muscle (acBr) blending with the medial aspect of bicipital aponeurosis in the cubital fossa. It also entrapped the median nerve and brachial artery due to its superficial position. The abnormality reported here might result in neurovascular compression symptoms in the upper limb and possible mechanical advantages or disadvantage in the flexion of elbow joint. To the best of our knowledge, the brachialis variant insertion we present here is rare in the list of its anomalies. We also discuss... |

| Foramen ovale and spinosum are important foramina of the greater wing of the sphenoid. Normal variations in their shapes and sizes are quite common and widely studied. In the present study, conducted in the Department of Anatomy of School of Medical Sciences, Universiti Sains Malaysia, 25 dried human skulls were examined for anatomic variations of the foramina of the greater wing of the sphenoid. During the study, we noticed anatomic variations of the foramen ovale and spinosum. In one skull, there was an abnormally large and irregular foramen ovale which was confluent with the foramen spinosum. In the second skull, the foramen spinosum was absent on the left side and in the 3rd skull it was duplicated on the right side. These variations are very rare and... |

| The vermis is described as the unpaired, median portion of the cerebellum to which the hemispheres are attached. Both the vermis and the hemispheres are formed by folia that, grouped together, are called lobules. The material analyzed consisted of a sample made up of 43 adult male cerebella fixed in 10% formaldehyde and sliced medially. The lingula was attached to the superior medullary velum in 100% (43) of the cerebella, varying only in size. In 80% (32) of the cerebella, the central lobe contained one folium; 7.5% (3) had two folia with the first larger than the second; 10% (4) had two folia with the second larger than the first; and 2.5% (1) had two folia of equal size. In 5% (2) of the cerebella, the folium of the vermis emerged from the declive; in... |

| At arteria femoralis, arteria profunda femoris is the main branch feeding the thigh. After iliofemoral embryological evolution many variations can be seen in this vessel. The absence of a. profunda femoris is one of the rare seen variation among these variations. Knowing the anatomy and variations of a. profunda femoris well, is important in low extremity ischemia, vessel surgery and angiography applications. In this study, 1036 films belonging to low extremity found in the Radiology department of School of Medicine of Cumhuriyet University were examined as retrospective. Among these films at four of them of male cases, absence of a. profunda femoris was detected. In cases at ages of 32, 37, 47 and 53 respectively, in the first and second case at the right... |

| Any compression of testicular arteries may lead to loss of spermatogenesis and gonadal hormone production, existence of the variational arteries is accountable in cases of vasoligation, orchidopexy and other surgical approach on them. Anomalies of the testicular blood arteries were observed during dissection of the pelvic cavity in a 68-year-old male cadaver. This report describes a very rare case of lack of testicular arteries. For the blood supply to the testis, thick deferential arteries form some vascular winding and loops and course accompanied by deferent duct to the testis. This case report would serve as ray of light for knowledge of the possible variations of the testicular arteries during surgical procedures. |

| Mitral valve cusps consist mainly of connective tissue and myocardium. Connective tissue fibres within the cusps have been demonstrated to exhibit sex variations in organisation. Mitral prolapse, a disease attributed to defects within the cusps occurs more commonly in females. Sex variations in valvular myocardium however remain to be studied. Possible variations in its organisation may enhance understanding of sex differences in prevalence of mitral prolapse. The aim of this study was to determine anatomical variations of mitral valvular myocardium by sex; by mean a comparative cross-sectional study. A total of 48 (27 male and 21 female) adult heart specimens obtained during autopsy at Nairobi City and Chiromo mortuaries after ethical approval were used.... |

| Unlike the venous system, variations in arterial anatomy are less frequent and most of them affect visceral arteries. In limbs, variations of the brachial artery are the most reported and at least six different patterns have been described so far. The commonest is the superficial brachial artery which lies superficially to the median nerve. Much less prevalent are the high origin of the radial artery (brachioradial artery) or the existence of a doubled brachial artery (accessory brachial artery). We present a previously undescribed pattern of brachial artery variation. During dissection of the right upper limb of a 60 year-old male embalmed cadaver, we found the bifurcation of the brachial artery in the proximal portion of the middle third of the arm. Its... |

| The spleen is the largest lymphoid organ. It is wedge shaped and measures about 1 inch thick, 3 inches broad and 5 inches long. It presents characteristic notches on its superior margin and has a hilum on the visceral surface. The aim was to study the anomalies related to size, shape and external features of the spleen and discuss their clinical importance. As there are not many reports on variations in size shape and features of spleen in the South Indian population, we decided to do this study on cadaveric specimens. We observed 50 spleens fixed with 10% formalin. Among the 50 spleens observed, 25 spleens (50%) were normal and had all the features explained in the textbooks. 25 spleens (50%) did not have any notches on the superior margin, 2 spleens (4%)... |

| The aim of this study was to verify the prevalence of the ossified superior transverse scapular ligament (STSL) on dry bones of scapulae. 221 dry bones were analyzed, (111 rights and 110 lefts), proceeding from Rio de Janeiro and of Santa Catarina, Brazil. As exclusion criterion, were not analyzed bones of children or damaged. For the quantitative analysis of the data, the software Graphad Instat was used. Fisher exact test was used considering the p ≤ 0,05 as significant. After analysis of the scapulae, 30,76% (68/ 221) presented the ossified STSL (p ≤ 0,0001) of which, 52,94% (36/68) were ossified on the right side and 47,05% (32/68) on the left one. The 153 scapulae that did not present the ossified STSL, it was observed in 19,6 %... |
