A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals International Journal of Morphology
Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da.
Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.

A Computed Tomographic Study of Umbilical Anatomy: The Relationship between Umbilical Thickness and Diameter International Journal of Morphology
Kim,Maru; Oh,Seong-Taek.
Laparoscopic surgeries were first introduced in the 1980s. More recently, similar techniques such as natural orifice transluminal endoscopic surgery and other advanced transumbilical surgeries have been developed. With all of these surgical advances, basic information about the umbilicus is lacking. This study evaluated the relationship between umbilical diameter and thickness, as well as the underlying vessels, in order to develop a simple means of assessing umbilical anatomy. We retroactively reviewed 842 computed tomography images that included the umbilicus. Umbilical thickness, diameter, type of vessel located beneath the umbilicus, depth to the vessel, and other parameters were measured. Age and sex were noted, and their relationship was analyzed as...

A Macroanatomical and Histological Study of the Uropygial Gland in the White Stork (Ciconia cicionia) International Journal of Morphology
Kozlu,Tolunay; Bozkurt,Yesim Akaydin; Ates,Sevinc.
The present study was aimed at the macroanatomical and histological investigation and the demonstration of the structural characteristics of the uropygial gland in the white stork. The uropygial gland of two adult male white storks constituted the material of the study. It was determined that the gland was situated subcutaneously in between the caudal aspect of the lumbosacral bone and the first coccygeal vertebrae. The gland was composed of two lobes, which displayed an oval appearance when viewed from above and resembled a water drop when observed medially. Tuft of feathers were present on the caudal margin of each lobe. The present study revealed that the uropygial gland of the white stork is a simple tubular gland, which discharges its secretion into...

A Novel Method for Localizing Nerve Entry Points During Spasticity Treatment International Journal of Morphology
Yang,Shengbo; Hu,Shuangjiang; Tian,Xufeng; Hu,Shuaiyu.
The nerve entry points (NEPs) cannot be accurately localized for the treatment of muscle spasticity in neurolysis. The aim of this study was to develop a new method of accurately localizing nerve entry points in relation to bony landmarks. NEPs in human cadavers were coated with barium sulfate. Method 1 consisted of horizontal and longitudinal reference lines being designated based on bony landmarks, followed by radiography and measurements using picture archiving and communication system software. Method 2 involved sewing the barium sulfate-soaked suture thread into the skin to designate the horizontal and longitudinal reference lines, followed by computed tomography (CT) scanning to determine the skin surface location and puncture depth for the NEPs....

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 study on the Gut contents of six Leathery Turtles Dermochelys Coriacea (Linnaeus) (Reptilia: Testudines: Dermochelyidae) from British waters and from the Netherlands Naturalis
Hartog, J.C. den; Nierop, M.M. van.
Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have...

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%)...

Potu,Bhagath Kumar; Gorantla,Vasavi Rakesh; Pulakunta,Thejodhar; Rao,M. S; Mamatha,T; Vollala,Venkata Ramana; Nayak,S. R.
During the laboratory dissection of the fore arm, an accessory head of flexor pollicis longus muscle has been observed unilaterally in the right upper limb of a male cadaver. It took its origin from the under surface of flexor digitorum superficialis muscle just distal to the origin of this muscle from medial epicondyle. On further dissection we have noticed that, the accessory belly was running downwards to the medial aspect of the tendon of flexor pollicis longus muscle for its insertion. Its possible role in anterior interosseous syndrome is discussed in detail with a brief review

Analysis and Clinical Importance of Superficial Arterial Palmar Irrigation and its Variants over 86 Cases International Journal of Morphology
Ottone,Nicolás Ernesto; Prum,Natalia; Dominguez,Mario; Blasi,Esteban; Medan,Carlos; Shinzato,Sergio; Finkelstein,Diana; Bertone,Vicente Hugo.
The classic description of the hand's superficial palmar arch is based on the anastomosis among the ulnar and radiopalmar arteries, a branch of the radial artery. However, the arch formation is highly variable regarding the size of the arteries that make it up and due to the existence of branches coming from other arteries and adding up as tributary to it. The objective of this paper is to classify these possible varieties, to define the formation of the arch, the reasons for its variable arrangement and the importance of its clinical and surgical applications. 86 formalized hands were dissected at 40%. There is prevalence concerning the size of the ulnar artery, with or without an arch. The anatomic knowledge of the variability in the arch formation...

Analysis of the Lingula Shapes in Macerated Mandibles of Brazilian Individuals International Journal of Morphology
Alves,Nilton; Deana,Naira Figueiredo.
The lingula of the mandible is a bone projection that limits medially the mandibular foramen, which is the region where the inferior alveolar neurovascular bundle penetrates. The lingula is an important anatomical landmark used in maxillofacial surgeries and to block the inferior alveolar nerve. The aim of this study was to analyze the different types of lingula found in mandibles of Brazilian individuals, considering aspects such as gender and race. One hundred thirty-two macerated mandibles of Brazilian adult individuals of both sexes, black and white skin colors, were used. The lingula was classified into four types: triangular, truncated, nodular and assimilated. The data were analyzed using Chi-square test and Fisher's exact test. The truncated shape...

Anatomia da raiz de espécies de Dyckia Schult. f. e Encholirium Mart. ex Schult. & Schult. f. (Bromeliaceae, Pitcairnioideae) da Serra do Cipó (Minas Gerais, Brasil), com especial referência ao velame Rev. Bras. Bot.
PITA,PATRÍCIA B.; MENEZES,NANUZA L..
O estudo anatômico da raiz em espécies de Dyckia e Encholirium mostra, como característica marcante, a presença de uma epiderme pluriestratificada, constituindo um velame. No epivelame, encontram-se os pêlos radiculares. A hipoderme é formada por células mortas de paredes espessadas e algumas células de passagem vivas de paredes não espessadas. Em diferentes níveis, apresenta-se uni ou plurisseriada e totalmente lignificada. Observa-se, também, o espessamento e a lignificação das paredes celulares de outras regiões do córtex em maior ou menor profundidade, dependendo do nível considerado (mais próximo do caule, mais espessado). Excluindo a raiz primária da planta jovem, todas as demais são adventícias, com medula ampla.
