Methods: CTA images of 1500 lower extremities of 750 patients (603 males, 147 females) with a mean age of 56.4±19.6 were evaluated retrospectively. The variations in the branching pattern of the popliteal artery and the frequency of these variations were examined and classified under three main types. Results: Type I–A was observed in 1422 extremities (94.8%) and noted as the most common branching pattern of the popliteal artery; Type I–B and Type I–C was observed in 39 extremities (2.6%); Type II in 37 extremities (2.4%) and Type III in 2 extremities (0.1%). The bilateral incidence of Type I–A was 90.8%. The incidence of bilateral variation was 0.4% for Type I–B and 0.1% for Type II–B. No statistically significant difference was found in terms of side and gender. Conclusion: Evaluation of lower extremity arteriograms is important in the diagnosis and surgery of peripheral vascular diseases. For this reason, it is important to know the branching pattern of the popliteal artery. We believe that the classification system that we used will be useful in evaluating the different variations, particulary the branching levels of the branches of the popliteal artery.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79209624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to determine the needs of the students in clinical internship education on anatomy and to plan the relevant anatomy subjects before clinical internships by rearranging the curriculum as needed. Methods: The study was carried out on a questionnaire form applied to 4th, 5th, and 6th-grade students of Bursa Uludağ University Faculty of Medicine. In addition to demographic information, 16 multiple-choice and open-ended evaluation questions were asked in the questionnaire. Results: 335 students participated in the study. 84.4% of the participants reported that they had needed basic anatomy knowledge and they had to study again before the clinical internship. 69.59% of the participants stated that among the courses taken in the basic sciences education period, anatomy should be integrated into the clinical internships. 88.24% of the participants stated that anatomy education should be integrated before starting clinical internships in the surgical departments. Conclusion: As a result of the feedback received from the students with the current study, it was seen that some of the anatomy information obtained during the preclinical basic sciences period was forgotten until the clinical internship period and they should be remembered again. We support that integrated clinical anatomy lessons should be taken into the clinical education period.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90741846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The block organization was implemented in 2006 in part to foster the horizontal integration of four basic science courses. However, simultaneous instruction in multiple courses presented a challenging workload to students, especially considering the large amount of information covered in anatomy. In an attempt to improve student outcomes, the gross anatomy course was compressed and frontloaded to the first 13 weeks of the foundational block while instructions of other courses were shifted later to make room for the frontloaded gross anatomy course. To assess the effect of frontloading of anatomy on students’ performance, we retrospectively compared the anatomy examination scores between before and after frontloading of the anatomy content. Methods: Student performance in the gross anatomy course was compared between the pre-frontloading (2013–2015) and post-frontloading (2016–2018) cohorts. Average scores of each examination category (quizzes, midterms, practical and written finals, and overall grades) were calculated and compared between the two cohorts. Results: Scores on the written final and practical final examinations and the overall grade in gross anatomy improved significantly (p<0.05) in the post-frontloading cohort (n=323) compare to the pre-frontloading cohort (n=343). Conclusion: Moving gross anatomy forward and offering a compressed course may be an option for educators looking to improve student performance without increasing student contact hours, concomitantly allowing focused learning and mastery of anatomy content.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85100516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acceptance into a DPT program implies that students have developed self-regulated learning strategies however, motivation behaviors are not typically assessed during the admissions process. The aim of this study was to determine direct effects of motivational behaviors and race/ethnicity on academic success and the moderating effect of race/ethnicity on motivational behaviors. Methods: Thirty-three first-year DPT students participated during their first foundational course, clinical anatomy. Motivation subscales from the motivated strategies for learning questionnaire (MSLQ) were used to assess student motivation behaviors which were then compared to course grades. Results: Self-efficacy for learning and performance was significantly correlated with course grade [r(31)=0.44, p< 0.05]. Course grade differed at a statistically significant level by race/ethnicity [t(31)=2.93, p<0.01]. Race/ethnicity (B=0.05, SE=0.01, b=0.42, p<0.008) and self-efficacy for learning and performance (B=0.02, SE=0.01, b=0.39, p<0.01), remained significantly related to course grade. Conclusion: Self-efficacy for learning and performance and ethnicity are factors that determine academic success and could be utilized in DPT programs to aid in the development of teaching strategies to support students.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79084048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphological changes occur in these muscles as a consequence of chronic musculoskeletal conditions (e.g. osteoarthritis), aging, and following hip joint replacement. Functional studies show unique activation profiles of the different compartments of gluteus medius and gluteus minimus; however, little is known of the fiber type composition of these muscles, which is an important consideration for understanding their functional and metabolic capabilities. Methods: Eight transverse muscle samples from each compartment of gluteus medius and gluteus minimus, and two samples from tensor fasciae latae were harvested from 11 cadavers, and processed for immunohistochemistry. Fast-twitch muscle fibers were stained with the MY-32 antibody to estimate the proportion of type II fibers comprising the muscles. Results: Individual muscle fiber composition profiles demonstrated that gluteus medius and gluteus minimus were similar in composition, supporting a predominantly postural function. Tensor fasciae latae had a higher proportion of type II fibers, suggesting a more phasic functional role. No differences were observed between compartments for gluteus medius, but the anterior compartment of gluteus minimus had a significantly higher proportion of type II fibers than the posterior. Conclusion: This study provides anatomical data for the fiber type composition profiles of the hip abductor muscles, contributing to the understanding of their metabolic and contractile capabilities. These data may be valuable when considering changes that occur at the cellular level in the hip abductor muscles under pathological conditions and with aging.","PeriodicalId":91999,"journal":{"name":"Anatomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87826602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
