A Rare Pattern of Brachial Artery Variation: Case Report International Journal of Morphology
Jacomo,A. L; Martinez,C. A. R; Saleh,S. O; Andrade,M; Akamatsu,F. E..
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...

A Rare Variation of the Testicular Blood Supply by the Deferential Artery International Journal of Morphology
Zheng,Yong; Yuan,Qianqian; He,Xin; Lei,Yueshan.
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.

A Study on the Anomalies of Liver in the South Indian Cadavers International Journal of Morphology
Nayak B,Satheesha.
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...

A Study on the Variations in the Formation of the Trunks of Brachial Plexus International Journal of Morphology
Shetty,Surekha D; Nayak B,Satheesha; Madahv,Venu; Braganza,Cilwyn Shalitha; Somayaji,S. N.
Brachial plexus shows several variations in its formation and branching pattern. Variations in the formation of the trunks are very rare. We studied 44 dissected specimens specifically for variations in the formation of the trunks of the brachial plexus. 5 cadavers (11.3%) showed variations in the formation of the trunks. All the variations were unilateral. In one cadaver (2.27%), the middle trunk was formed by union of C7 and C8 roots and lower trunk was formed by T1 root. Upper and middle trunks were fused with each other in one specimen (2.27%). In 3 specimen (6.81%), the C5 root pierced scalenus anterior before joining C6 to form the upper trunk. Knowledge of its variations is of importance to orthopedic surgeons, neurologists and anesthesiologists.

A Study on the Variations of Size, Shape and External Features of the Spleen in South Indian Population International Journal of Morphology
Nayak B,Satheesha; Somayaji,S. N; Soumya,K. V.
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%)...

Absence of the Arteria Profunda Femoris International Journal of Morphology
Otag,I; Çimen,M; Solak,O; Otag,A; Çimen,F. G; Kosar,M. I.
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...

Agroclimatic classification of the semi-arid tropics. II. Identification of classification variables. Repositório Alice
REDDY, S. J..
Eight agroclimatic variables related to crop production potential in the semi-arid tropics of India are identified. These are used to assess dry-seeding feasibility, water-logging hazard, risk in agricultural production, cropping patterns and their spatial distribution, using data from 80 locations in India. Regression analysis has been used to identify differences between locations at different scales, i.e., local differences caused by orography, region differences associated with general circulation patterns. Using the data of 08 variables from 199 locations in India and two west African countries (Senegal and Upper Volta) three dissimilarity parameters were derived. The basic dissimilarity observed on a continental scale is that for the same amount of...

Anatomic Variants of Foramen Ovale and Spinosum in Human Skulls International Journal of Morphology
Khan,Aaijaz Ahmed; Asari,Mohd Asnizam; Hassan,Asma.
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...

Iterezote,Ana Maria; Medeiros,Alisson Dantas de; Barbosa Filho,Rômulo César Costa; Petrella,Selma; Andrade Junior,Luiz Carlos de; Marques,Sergio Ricardo; Prates,José Carlos.
Variations in the trajectory of the brachiocephalic trunk and the common carotid artery predispose to disorders which might be critical in a tracheotomy and/or surgeries. Dissection of 110 formol fixed adult cadavers, both sexes, were performed to increase the anatomic knowledge of the neck vessels and its variations. Cadavers were from the Laboratory of Descriptive and Topographic Anatomy of the Federal University of São Paulo- Paulista Medical School- UNIFESP-EPM. In 109 of these cadavers no variations were found while in one (0.9 %) it was possible to observe a variation in the trajectory of the brachiocephalic trunk and in the right common carotid artery.

Cerebellar Vermis: Topography and Variations International Journal of Morphology
Bispo,Rodrigo Freitas Monte; Ramalho,Antonio José Casado; Gusmão,Luiz Carlos Buarque de; Cavalcante,Amundson Portela  de Holanda; Rocha,Amauri Clemente da; Sousa-Rodrigues,Célio Fernando de.
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...

Clinical and Functional Significance of Accessory Brachialis Muscle: An Unique Anatomical Variant International Journal of Morphology
Sirisinagandla,Sreenivasa Rao; Potu,Bhagath Kumar.
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...

Genetic diversity of guava (Psidium guajava L.) from Central Mexico revealed by morphological and RAPD markers Phyton
Valera-Montero,LL; Muñoz-Rodríguez,PJ; Silos-Espino,H; Flores-Benítez,S.
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...
