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... |

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. |

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 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%)... |

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... |

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... |

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... |

Guava fruit produced in Calvillo, Aguascalientes (Mexico) is considered to be of the best quality in this country. Nevertheless, growers from this place empirically know that there is a noticeable variation among individual trees within the same orchard, and variation among individuals from different orchards. In order to have a clear evidence of this, morphology analysis of guava was performed taking data from seventy nine individuals out of thirty six orchards, while RAPD was performed on a subset of twenty six individuals. Similarity was found for morphology data ranging from 87-100%, while similarity from RAPD data ranged from 30-100%. Combined data of RAPD and morphology showed similarity greater than 80%. Clades from combined data sorted genotypes... |

ABSTRACT We aimed to estimate litter size and litter uniformity genetic parameters and genetic trends of Landrace pigs at birth and at three weeks by using multitrait analyses for 2,787 litters. The following litter traits were evaluated: number of piglets born alive (NBA), within-litter weight mean at birth (MBW), within-litter weight standard deviation at birth (SDB), within-litter weight coefficient of variation at birth (CVB), number of piglets at three weeks (NT), within-litter weight mean at three weeks (MT), within-litter weight standard deviation at three weeks (SDT), and within-litter weight coefficient of variation at three weeks (CVT). Heritability estimates for NBA, MBW, SDB, and CVB were 0.09±0.04, 0.31±0.08, 0.01±0.04, and 0.07±0.05,... |

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 %... |

Radix labiata is a widely distributed Palaearctic freshwater snail. This work aims to improve the knowledge of the intraspecific variability in the most important characters used for its determination. To find out which characters are really suitable to distinguish this species from other similar Radix species an integrative approach was applied, involving morphological and molecular data.Molecular sequences of the nuclear spacer fragment ITS-2 and/or the mitochondrial gene fragment cyt-b were obtained from 26 individuals of R. labiata from different regions of Europe, including type localities of Limnaeus pereger labiatus. From the subsample of 24 specimens of which sequences of both gene fragments were available, the variability of several characters... |
