Spatial Visualization of Human Anatomy through Art Using Technical Drawing Exercises

Everyone can draw: An inclusive and transformative activity for conceptualization of topographic anatomy

Anatomical drawing traditionally involves illustration of labeled diagrams on two-dimensional surfaces to represent topographical features. Despite the visual nature of anatomy, many learners perceive that they lack drawing skills and do not engage in art-based learning. Recent advances in the capabilities of technology-enhanced learning have enabled the rapid and inexpensive production of three-dimensional anatomical models. This work describes a "drawing on model" activity in which learners observe and draw specific structures onto three-dimensional models. Sport and exercise sciences (SES, n = 79) and medical (MED, n = 156) students at a United Kingdom medical school completed this activity using heart and femur models, respectively. Learner demographics, their perceptions of anatomy learning approaches, the value of the activity, and their confidence in understanding anatomical features, were obtained via validated questionnaire. Responses to 7-point Likert-type and free-text items were analyzed by descriptive statistics and semi-quantitative content analysis. Learners valued art-based study (SES mean = 5.94 SD ±0.98; MED = 5.92 ± 1.05) and the "drawing on model" activity (SES = 6.33 ± 0.93; MED = 6.21 ± 0.94) and reported enhanced confidence in understanding of cardiac anatomy (5.61 ± 1.11), coronary arteries (6.03 ± 0.83), femur osteology (6.07 ± 1.07), and hip joint muscle actions (5.80 ± 1.20). Perceptions of learners were independent of both their sex and their art-based study preferences (p < 0.05). Themes constructed from free-text responses identified "interactivity," "topography," "transformative," and "visualization," as key elements of the approach, in addition to revealing some limitations. This work will have implications for anatomy educators seeking to engage learners in an inclusive, interactive, and effective learning activity for supporting three-dimensional anatomical understanding.

Investigation of factors that influence the relationship between mental rotation ability and anatomy learning

BACKGROUND

Mental rotation is a cognitive process that involves the rotation of a mental representation of an object. This ability is important for medical students in studying anatomy as this subject requires the understanding of positional relations between organs.

OBJECTIVES

To find the effect of video learning of anatomy, training, gender, and type of practical exam on mental rotation ability. Also, to find correlation between mental rotation and anatomy scores.

METHODS

Two groups were recruited: group A studied practical anatomy online using videos due to the COVID-19 pandemic lockdown; group B studied anatomy labs on-campus on plastic models. Both groups underwent a mental rotation test. Group A took labs on-campus during their second year and this was considered a training course for their mental rotation ability. Both groups, then, took a second mental rotation test. Group A was finally given a practical anatomy exam using plastic models.

RESULTS

Males scored higher than females, though not significantly. The intervention course produced no significant change in mental rotation score of group A. Mental rotation score was correlated more with the theoretical anatomy exams than the MCQ-based practical exam, for both groups. For group A, mental rotation was better correlated with the model-based than the MCQ-based practical exam, especially the post-training score.

CONCLUSION

For students to take full advantage of their mental rotation ability, not only their practical anatomy sessions but their practical anatomy exams should be on anatomical specimens and not just videos or images.

Learning Pelvic Anatomy and Pathology Through Drawing: An Interactive Session in the Obstetrics and Gynecology Clerkship

Introduction

Within undergraduate medical education, there is a gap between students' understanding of anatomy and application of that knowledge within surgical specialties. The integration of drawing, in conjunction with traditional learning, has been shown to increase retention and understanding of information. Currently, no educational curriculum integrates drawing to aid in medical students' understanding of surgical pelvic anatomy. We anticipated that the utilization of drawing anatomy in an OB/GYN clerkship would enhance students' ability to explain surgical pelvic anatomy and pelvic pathology.

Methods

At the beginning of the OB/GYN clerkship, third-year medical students participated in an interactive, 1.5-hour session requiring them to draw pelvic anatomy, present their work, and explain topics related to pelvic surgery and pathology to the other clerkship students. At the end of their clinical rotation, the students were invited to complete a five-item survey to assess long-term retention and understanding of concepts presented in the session. Frequencies and percentages were calculated for all categorical/ordinal variables to describe survey participants and question responses.

Results

Thirty-seven of 44 respondents (84%) reported that the anatomy interactive session prepared them for the surgical portion of the OB/GYN clinical rotation. Thirty-five respondents (80%) reported that drawing the pelvic structures helped their understanding of pelvic pathology; 33 respondents (75%) reported they had a thorough understanding of pelvic anatomy after taking the OB/GYN anatomy interactive educational session (p < .001).

Discussion

Our session shows that integrating drawing and anatomy increases students' ability to discuss pelvic pathology and surgical anatomy.

Visuospatial ability and student approach to learning as predictors of academic performance on written versus laboratory-based assessments in human anatomy

As hours devoted to human anatomy curricula fall under threat and curricular delivery methods remain in flux, many new teaching innovations are emerging, which require comprehensive evaluation to ensure evidence-based teaching is maintained. Although grades are the predominant measure of 'learning', alternative metrics can assess more nuanced and meaningful outcomes. Two common predictors of students' three-dimensional understanding of the body and depth of learning are visuospatial abilities and approaches to learning, respectively. This study evaluated and compared the relative predictive power of these metrics on written and laboratory-based assessments in a human anatomy course. Deep approaches to learning and visuospatial abilities were expected to positively correlate with overall performance, with visuospatial abilities being the more salient predictor, especially on laboratory-based assessments. Additionally, visuospatial abilities were expected to positively correlate with deep learning approaches and negatively correlate with surface learning approaches. Multiple linear regression models controlling for covariates found that both visuospatial abilities (p = 0.049; p = 0.014) and deep learning approaches (p = 0.001; p = 0.001) were independent significant predictors of final and laboratory-based grades, while only deep learning approaches were significantly predictive of written grades (p = 0.007). There was no significant relationship between visuospatial abilities and approaches to learning. Given these findings and the increased reliance on visuospatially demanding digital learning activities in anatomy, both metrics should be considered when evaluating the impact of teaching innovations. Further, educators should design learning resources and environments that train visuospatial abilities and promote deeper learning approaches to maximize students' success.

Can drawing instruction help students with low visuospatial ability in learning anatomy?

Visuospatial skills are considered important attributes when learning anatomy and there is evidence suggesting that this ability can be improved with training techniques including drawing. The Mental Rotations Test (MRT) has been routinely used to assess visuospatial ability. This study aimed to introduce students to drawing as a learning strategy for anatomy. Undergraduate speech science anatomy students took part in a drawing tutorial (n = 92), completed an MRT test, pre- and post-tutorial tests, and surveys regarding their use and attitudes toward drawing as a study tool. The impact on their examination performance was then assessed. Regardless of MRT score or attitude to drawing, students who participated in the drawing tutorial demonstrated immediate improvement in post-tutorial test scores. Students in the drawing group performed better in most anatomy components of the examination, but the result did not reach statistical significance. There was only a positive correlation between MRT score and one type of anatomy question (non-image-based) and speech physics questions (r = 0.315, p = 0.002). The unexpected finding may relate to the MRT which assesses spatial rather than object visualization skills. Students who liked drawing also performed significantly better in word-based and speech physics questions. It is likely that the style of identification question did not require the mental manipulation ability assessed in the MRT. This study demonstrated that students with lower MRT scores are not outperformed in all aspects of anatomy assessment. The study highlights the importance of a more nuanced understanding of visuospatial skills required in anatomy.
