Of the dipteran species collected during the study, L. cuprina and C. albiceps could be important for further forensic studies since they were collected from the carcasses and also observed from the rearing units.
Background. Traditional academic-led anatomy teaching methods, such as didactic lectures and cadaver dissections, are on the decline, as more student-led teaching methods are being adopted. Objectives. To assess medical students' perspectives on the teaching objectives achieved by traditional teaching methods (lectures, cadaver dissections and tutorials) used in the anatomy course. Methods. A cross-sectional survey comprising a matrix questionnaire was performed among selected 1st-year-5th-year medical students, using stratified random sampling. The students were requested to select a score between 0 and 5 to represent the fit between the learning outcome and the teaching method, with 0 being no fit and 5 representing a perfect fit. Results. Lectures had the highest mean score of 3.871 for the ability to provide medical vocabulary. Cadaver dissection had the highest mean score of 3.488 for its ability to develop team skills. The highest mean score of 3.415 for all three teaching methods combined was recorded for the learning outcome relating to imparting an anatomical foundation, while the lowest mean score of 2.731 was recorded for the development of skills in order to follow complicated instructions. However, no teaching method had an excellent fit (mean ≥4.5) with any of the teaching objectives. Conclusion. The study showed that the three teaching methods being used in the anatomy course were, to a great extent, useful to impart the skills and content base. However, other teaching methods, such as problem-based and team-based learning, have to be considered to achieve the other important learning outcomes.
The Maxillary Artery (MA) is known to vary in its relationship to lateral pterygoid muscle (LPM) and its relationship to inferior alveolar nerve (IAN) and lingual nerve (LN). The variation poses surgical challenges and complications in anesthetic injection. This cadaveric study sought to describe the anatomy of the inferior alveolar nerve, lingual nerve and maxillary artery in infratemporal fossa and its associated variations. Thirty hemi- sections from 15 male cadavers were used. Dissection of the infratemporal fossae was done to expose the MA, LPM, IAN and LN. The relationship of MA to LPM was noted, roots of IAN were noted and relationship of structures were scrutinized. Pictures were taken for further analysis. Out of 30 hemi-sections, dissected 43.3% had a medial relationship to LPM while 56.7% of MA had a lateral relationship. Three (20%) of the cadavers showed asymmetry whereby MA passed on the medial side of LPM on one side while the other side it passed on the lateral aspect. Most of the hemi- sections (86.7%) had IAN originating with one (1) root, 3 hemi-sections (10%) with two roots and one (3.3%) with three roots. Only one hemi-section showed presence of a communicating branch between IAN and LN. The variations in MA in this population displays patterns comparable to other populations. There was high prevalence of MA passing lateral to LPM, which is consistent with studies done elsewhere. There were variations of IAN originating with multiple roots and presence of communicating branch between IAN and LN, which was consistent with case reports in literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
