Effect of Image-Slicing Exercises on Students’ Understanding of Cross-Sectional Anatomy

Abstract

The study examines the effect of image-slicing exercises on students’ understanding of cross-sectional anatomy, with emphasis on the use of sequential anatomical images to improve students’ recognition of structures and their spatial relationships across different levels of the body. Cross-sectional anatomy requires students to interpret anatomical structures as they appear in different planes and to understand how structures change in position, shape, and relationship from one section to another. Image-slicing exercises may provide an interactive approach that helps students develop these skills and strengthen their three-dimensional understanding of anatomy. The study will assess students’ understanding of cross-sectional anatomy before and after exposure to structured image-slicing exercises. The specific objectives will include determining students’ baseline ability to identify anatomical structures on sectional images, exposing students to sequential image-slicing activities, assessing their understanding of structural relationships following the intervention, and comparing their performance before and after the exercises. A quasi-experimental research design will be adopted for the study. An appropriate sample of undergraduate students will be selected using a suitable sampling technique and exposed to structured image-slicing exercises involving selected regions of the human body. The exercises will involve the interpretation of serial cross-sectional images, identification of anatomical structures at different levels, tracing structures across consecutive sections, and relating sectional appearances to their three-dimensional anatomical positions. Data will be collected using standardized cross-sectional anatomy assessments and analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation, with appropriate inferential tests applied where necessary. The study is expected to reveal improved understanding of cross-sectional anatomy among students following exposure to image-slicing exercises. Students may demonstrate better recognition of structures, interpretation of anatomical relationships, identification of changes across consecutive sections, and understanding of spatial orientation. Greater difficulties may remain in interpreting images containing closely related structures, complex anatomical regions, overlapping structures, or less familiar sectional appearances. The findings will be useful to anatomists, anatomy educators, radiology educators, medical students, radiography students, physiotherapy students, and other healthcare trainees involved in anatomical imaging and clinical education. The study may provide useful information on the value of image-slicing activities in developing students’ spatial reasoning and interpretation of sectional anatomy. It may also assist educators in designing practical image-based activities that complement conventional lectures, atlases, models, and radiological image teaching. The study will conclude by determining the effect of structured image-slicing exercises on students’ understanding of cross-sectional anatomy. It is recommended that sequential image-slicing activities should be incorporated into anatomy teaching to provide students with repeated opportunities to trace structures across different anatomical levels and develop stronger spatial understanding. Further studies involving larger and more diverse student populations should be conducted to provide additional evidence on the effectiveness of image-based approaches in improving cross-sectional anatomy learning.
