Here we present a unique case of variation in the branching pattern of the coeliac trunk. In the present case, the coeliac trunk was replaced by two separate arterial trunks. The first arterial trunk bifurcated into the left gastric and the left hepatic arteries. The second arterial trunk bifurcated into a splenic artery and a hepato-gastroduodenal trunk. The hepato-gastroduodenal trunk presented an unusual course and termination. The right hepatic artery arising from the hepato-gastroduodenal trunk also showed a variant course. Such rare variations are important for gastroenterological surgeons and interventional radiologists due to increase in number of transplantation surgeries and live donor liver transplantations.

Jae Sung CHO ; Jinu KIM ; Sang Pil YOON

Anatomy & Cell Biology.2015;48(2):144-146. doi:10.5115/acb.2015.48.2.144

Dual left anterior interventricular coronary artery (also called left anterior descending artery, hereafter referred as LAD) is a rare congenital coronary artery anomaly. Notably, type IV dual LAD has never been reported in Koreans. During a routine dissection, a new variant of type IV dual LAD was found in a 57-year-old Korean male cadaver, whose cause of death was unknown. One LAD originated from the right coronary artery, coursed through the anterior interventricular sulcus, but did not reach the apex cordis. The other LAD arose from the left coronary artery, never entered the anterior interventricular sulcus through its course, but reached the apex cordis, where it met the posterior interventricular branch of the right coronary artery. This is the first report on a new variant of type IV dual LAD in Koreans, which is of clinical importance during procedures containing the coronary artery.

Anatomy & Cell Biology.2015;48(2):138-143. doi:10.5115/acb.2015.48.2.138

A flipped classroom is a learner centered approach in which the learner is responsible to attend the class with basic understanding of the subject to fully participate and engage in discussions. The aim of this study was to evaluate students' perception of flipped classroom approach for neuroanatomy module and assess the impact on their performance and attitudes. The subject chosen to evaluate the flipped classroom model for first year medical students was clinical neuroanatomy. One hundred and thirty first year medical students participated in the study module. Students were divided into five groups and five case scenarios pertaining to various clinically relevant regions of the neuraxis, with varying anatomical complexity were generated. The pre- and post-tests were designed to specifically test the declared learning objectives of the session. The perception of the students regarding this model of teaching and learning was also evaluated. Eighty-six percent of students felt that the flipped classroom approach was better at fulfilling the stated learning objectives than the conventional didactic teaching, 92% felt that the work-sheet with questions provided prior to the class enabled a better understanding of the subject and 87% were of the opinion that the web sources with references kindled a greater interest to read as compared with didactic lectures. The paired t test showed highly significant differences between the pre and post-test scores. Student response to the flipped classroom structure was largely positive, indicating it to be an approach worth pursuing in future years.

Most of foot pain occurs by the entrapment of the tibial nerve and its branches. Some studies have reported the location of the tibial nerve; however, textbooks and researches have not described the posterior tibial artery and the relationship between the tibal nerve and the posterior tibial artery in detail. The purpose of this study was to analyze the location of neurovascular structures and bifurcations of the nerve and artery in the ankle region based on the anatomical landmarks. Ninety feet of embalmed human cadavers were examined. All measurements were evaluated based on a reference line. Neurovascular structures were classified based on the relationship between the tibial nerve and the posterior tibial artery. The bifurcation of arteries and nerves were expressed by X- and Y-coordinates. Based on the reference line, 9 measurements were examined. The most common type I (55.6%), was the posterior tibial artery located medial to the tibial nerve. Neurovascular structures were located less than 50% of the distance between M and C from M at the reference line. The bifurcation of the posterior tibial artery was 41% in X-coordinate, -38% in Y-coordinate, and that of the tibial nerve was 48%, and -10%, respectively. Thirteen measurements and classification showed statistically significant differences between both sexes (P<0.05). It is determined the average position of neurovascular structures in the human ankle region and recorded the differences between the sexes and amongst the populations. These results would be helpful for the diagnosis and treatment of foot pain.

Maturation of neurons of the myenteric plexus (MP) of human fetal sigmoid colon was studied at various weeks of gestation (WG). There is abundant literature on the development of MP in various segments of the gut but there are fewer reports on the development of MP in human sigmoid colon which is a site of various disorders. Sigmoid colonic segments from 12 aborted foetuses aged 14-23WG were processed for NADPH histochemistry. Stereologic evaluation of the neuronal cell profiles, numerical density, number of neurons per ganglion and myenteric fraction was conducted using using imageJ software. According to gestational age, foetuses were assigned into two groups (group 1 [n=7], less than <17WG and group 2 [n=5], more than >17WG). The overall size of neuronal cell profiles in the MP was significantly increased (P<0.05). The numerical density of neurons decreased in group 2 in comparison to group 1, the number of neurons per ganglion and myenteric fraction were increased in group 2 but all these were not statistically significant. This study revealed that the maturational event increases after 17WG and extensive innervations is established at 23WG. During prenatal life there is an increase in the neuronal cell size from 14-23WG signifying maturational process. Such studies are essential for clinicians and surgeons to correlate the normal and pathologic development of the enteric nervous system.

The subhepatic position of the cecum and appendix is a result of embryological reasons. Subhepatic appendicitis can cause diagnostic dilemmas. During the dissection of an adult male cadaver aged approximately 70 years, the subhepatic position of the cecum and appendix was noted. The appendix made a "U"-shaped bend and its tip was located in the paracolic position. The cecum had appendices epiploicae, and the terminal part of the ileum was retroperitoneal and had ascended vertically to the cecum from the right iliac fossa. Functionally, the sessile part of the ileum might restrict its peristaltic movements. The abnormal position of the terminal ileum might be mistaken for an ascending colon during laparoscopic surgery. The subhepatic position of the cecum and appendix might cause confusion in the diagnosis of acute appendicitis because the tenderness in such cases is not located at the McBurney's point.

Anatomy & Cell Biology.2013;46(4):291-295. doi:10.5115/acb.2013.46.4.291

Nerve root anomalies are frequently underrecognized regardless of the advances in imaging studies; they are also underappreciated and underreported when encountered surgically. The classification of conjoined nerve roots is based on whether the nerve root emerges at an abnormal level or from an anastomotic branch. In the present report, we describe case with a conjoined nerve root that emerged at a more caudal level than that normally observed that was an undiagnosed on preoperative imaging studies. We also discuss the atypical imaging features obtained through preoperative imaging studies. As observed in the present case, preoperative recognition and diagnosis of such anomalies offer the best opportunity of performing a successful procedure and preventing inadvertent damage to nerve roots intraoperatively.

Anatomy & Cell Biology.2013;46(4):285-290. doi:10.5115/acb.2013.46.4.285

Placental morphology and cellular arrangement are altered in maternal diseases such as preeclampsia (PE) in which oxygen delivery from the mother to the fetus is greatly disturbed, ultimately resulting in cellular oxidative stress. The present study was conducted at the Department of Anatomy and included 112 placentas (56 each from mothers with and without PE [controls]) collected at the Department of Obstetrics and Gynecology. A histological study was performed using hematoxylin and eosin staining. The morphology of stem and terminal villi (TV) was studied, and the surface area and diameter of TV and capillaries were measured. The gross placental morphometrical study revealed that the mean placental weight, thickness, diameter, and surface area were significantly lower in placentas with PE than in controls. The histomorphometrical findings of the villous surface area and diameter were lower in placentas with PE, whereas the TV density was higher in placentas with PE than in controls, and the differences were significant (P<0.0001). In these TV, the diameter and density of fetal blood vessels of placentas with PE were significantly lower than those of controls (P<0.05). In conclusion, the both morphological and histological changes in PE placentas are indicative of the pathogenesis of maternal and fetal morbidity and mortality in women with PE. The observed and comparative histomorphometrical changes indicate a decline in all aspects of the PE placenta, except the number of TV.

Expression of carbonic anhydrase IX in human fetal joints, ligaments and tendons: a potential marker of mechanical stress in fetal development?.

Ji Hyun KIM ; Seppo PARKKILA ; Shunichi SHIBATA ; Mineko FUJIMIYA ; Gen MURAKAMI ; Baik Hwan CHO

Anatomy & Cell Biology.2013;46(4):272-284. doi:10.5115/acb.2013.46.4.272

Carbonic anhydrase type IX (CA9) is known to express in the fetal joint cartilage to maintain pH against hypoxia. Using paraffin-embedded histology of 10 human fetuses at 10-16 weeks of gestation with an aid of immunohistochemistry of the intermediate filaments, matrix components (collagen types I and II, aggrecan, versican, fibronectin, tenascin, and hyaluronan) and CA9, we observed all joints and most of the entheses in the body. At any stages examined, CA9-poisitive cells were seen in the intervertebral disk and all joint cartilages including those of the facet joint of the vertebral column, but the accumulation area was reduced in the larger specimens. Glial fibrillary acidic protein (GFAP), one of the intermediate filaments, expressed in a part of the CA9-positive cartilages. Developing elastic cartilages were positive both of CA9 and GFAP. Notably, parts of the tendon or ligament facing to the joint, such as the joint surface of the annular ligament of the radius, were also positive for CA9. A distribution of each matrix components examined was not same as CA9. The bone-tendon and bone-ligament interface expressed CA9, but the duration at a site was limited to 3-4 weeks because the positive site was changed between stages. Thus, in the fetal entheses, CA9 expression displayed highly stage-dependent and site-dependent manners. CA9 in the fetal entheses seemed to play an additional role, but it was most likely to be useful as an excellent marker of mechanical stress at the start of enthesis development.
