The objective of this case report is to alert the cardiologists and radiologists about the possibility of an extremely rare trifurcation of the right coronary artery. During dissection classes, an early trifurcation of the right coronary artery (RCA) was observed in an adult male cadaver aged approximately 65 years. The RCA had a normal origin from the anterior aortic sinus. After a course of just 2 mm, it trifurcated into a conus artery, a huge right ventricular branch and then a main continuation of the RCA...

Osteochondromas develop as cartilaginous nodules in the periosteum of bones. They are the commonest benign tumors of the skeleton, generally observed in the long bones. Rarely, they are also found in the axial skeleton, flat bones of skull and facial bones. During a regular dissection, we came across a solitary osteochondroma in posterior surface of the body of the right pubic bone. Histopathology of the bony projection confirmed the typical features of the osteochondroma. The symptomatic osteochondromas are usually evaluated during radiographic examination...

Cardiac arrest (CA) is sudden loss of heart function and abrupt stop in effective blood flow to the body. The patients who initially achieve return of spontaneous circulation (RoSC) after CA have low survival rate. It has been known that multiorgan dysfunctions after RoSC are associated with high morbidity and mortality. Most previous studies have focused on the heart and brain in RoSC after CA. Therefore, the aim of this research was to perform serological, physiological, and histopathology study in the lung and to determine whether or how pulmonary dysfunction is associated with low survival rate after CA...

CD57 (synonyms: Leu-7, HNK-1) is a well-known marker of nerve elements including the conductive system of the heart, as well as natural killer cells. In lung specimens from 12 human fetuses at 10-34 weeks of gestation, we have found incidentally that segmental, subsegmental, and more peripheral arteries strongly expressed CD57. Capillaries near developing alveoli were often or sometimes positive. The CD57-positive tissue elements within intrapulmonary arteries seemed to be the endothelium, internal elastic lamina, and smooth muscle layer, which corresponded to tissue positive for a DAKO antibody reactive with smooth muscle actin we used...

Although the students are subjected to some formative exams throughout the problem based learning units, feedback is not given appropriately and timely. Students want to know and use the reasoning behind judgments and always complain that assessment criteria need to be explained. The aim of this project is to implement a two-way feedback delivery (TWFD), in which both faculty and students have an opportunity to discuss their reflections on learning and examination processes. An Anatomy formative assessment is introduced to 100 students followed by implementation of TWFD...

Several authors have made efforts to define the position of the axillary nerve within deltoid muscle and to calculate the so called safe area for this nerve but it still remains a matter of debate. The primary aim of the study was to investigate the acromio-axillary (AA) distance and its correlation with upper arm length. The secondary aim was to re-define the safe area for axillary nerve within deltoid muscle. Sixty shoulders of thirty adult human cadavers were dissected using standard methods. The distance from the anterior and posterior edge of acromion to the upper border of the course of the axillary nerve was measured and recorded as anterior and posterior AA distance respectively...

The fissures of lungs are embryologically separating the bronchopulmonary segments, which later on persist in interlobar planes of fully developed lung. Fifty lungs (23 right side and 27 left side), obtained during routine dissection and preserved in formalin constituted the material for present study. In them, variations in fissures and lobes of lung were observed and compared with the previous studies. Seven right sided and 14 left sided lungs showed incomplete oblique fissure. Incomplete horizontal fissure of right lung was observed in eight lungs while it was completely missing in three specimens...

Pulleys are thickened regions in flexor tendons sheaths of the digits. They are essential and act as fulcrum for the flexion and extension of the digits. The arrangement and number of pulley system differs greatly between the thumb and other digits. There is paucity of literature regarding the pulley system of thumb. We aimed to study the morphometry of the pulley system of the thumb in Indian cadavers. Dissection was carried out in 55 adult human cadaveric thumbs. The most common morphologic pattern of pulley observed in the thumb is type III (30 thumbs)...

The authors report a rare variation of the coeliac trunk, renal and testicular vasculature in a 27-year-old male cadaver. In the present case, the coeliac trunk and superior mesenteric artery was replaced by a modified coeliacomesenteric trunk formed by hepato-gastric and superior mesenteric arteries. Here the hepato-gastric artery or trunk contributed towards the total hepatic inflow as well as a gastro-duodenal artery. A separate right gastric artery and an additional superior pancreatico-duodenal artery was also found in addition with a retro-aortic left renal vein and a bilateral double renal arterial supply...

Cimetidine is an H2 receptor antagonist that has an antiandrogenic effect. It intervenes with the conversion of testosterone into estrogen in the Sertoli cells with accompanying testicular structural changes. In the present study, the microscopic and the ultrastructural changes induced by cimetidine and the effect of vitamin B12 as a protective agent on rat testes were studied. Immunoexpression of estrogen receptor β (ERβ) in testes was evaluated. Twenty-four adult male rats were divided into four groups: control, cimetidine-treated, vitamin B12 treated, and combined cimetidine and vitamin B12 treated...

Measuring skeletal development throughout juvenile growth can provide a greater understanding into the health, hormonal function and genetics of children. The metacarpals have been of interest for their potential to provide insights into healthy juvenile skeletal development. This study investigated the growth patterns of developing females from isolated communities who had varied diets. Anthropometrical measurements and hand-wrist X-rays were taken of 353 juvenile females from three populations: Pari Coastal Village and Bundi Highlands Village, Papua New Guinea (PNG); and Brisbane, Australia between 1968 to 1983...

Significant variations exist in the occurrence, form, and position of supraorbital nerve exits through the frontal bone. Detailed knowledge of the positional variations of supraorbital exits is important to ensure safe and successful regional anesthesia, and to avoid iatrogenic nerve injuries during surgery of the orbitofacial region. Supraorbital nerve exits from 116 sides of 58 dry intact adult skulls (37 male and 21 female) in a Sri Lankan population were examined to determine the morphological features and the precise position in relation to the facial midline, temporal crest of frontal bone, and frontozygomatic suture...

The Chinese philosophy of Confucianism said "What I heard I forgot, what I see, I remember, what I do, I understand." During this time, most of the teaching and learning process relies on viewing and listening modalities only. As a result, much information does not last long in memory as well as the material understanding achieves became less deep. In studying anatomy science, drawing is one of effective important methods because it is an integration of ideas and knowledge of vision thereby increasing comprehension and learning motivation of college students...
