Many of the new and proposed veterinary schools are including
the online teaching of veterinary anatomy as a cornerstone of their curriculum,
promising accessibility and cutting-edge technology.
But can virtual platforms truly replace the tactile, three-dimensional understanding gained from traditional dissection? In the race to modernize education, are we sacrificing hands-on skills essential for future veterinary surgeons?
The debate between hands-on dissection and online or virtual learning for veterinary anatomy has become increasingly relevant as educational tools evolve.
Pros of Hands-On Dissection
Tactile Learning Experience: Handling real specimens provides a direct tactile experience, allowing students to feel the texture, density, and spatial relationships of anatomical structures.
Three-Dimensional Understanding: Real cadavers offer an unparalleled opportunity to understand the physical orientation and interconnection of structures in a real-world context.
Variation in Anatomy: Real specimens show natural anatomical variations, pathology, and anomalies, preparing students for the diversity they’ll encounter in practice.
Kinesthetic Memory: Physically manipulating specimens helps some students reinforce their learning through kinesthetic memory.
Diagnostic Skill Development: The process of dissection enhances observational and critical thinking skills, which are essential for diagnosing clinical conditions.
Cons of Hands-On Dissection
Ethical and Moral Concerns: Some students may feel discomfort with the use of cadavers, raising ethical questions about the procurement and use of animals.
Resource Intensive: Dissection requires significant resources, including the cost of specimens, preservation, disposal, and laboratory facilities.
Limited Accessibility: Students at remote or underfunded institutions may not have the same access to cadaveric resources.
Health Risks: Exposure to formalin and other preservatives can pose health risks to students and staff.
Environmental Concerns: Cadaver storage and disposal have environmental impacts, including the use of chemicals and energy-intensive processes.
Pros of Online/Virtual Anatomy Learning
Accessibility: Online tools can be accessed anywhere, making learning more inclusive for students from remote or underfunded institutions.
Standardization: All students have access to the same high-quality, detailed, and annotated anatomical models, reducing disparities in learning resources.
Interactivity and Repetition: Virtual anatomy platforms often allow students to zoom, rotate, and layer anatomical structures, facilitating repeated exploration at their own pace.
Cost-Effective: After initial development, online resources are less costly to maintain and distribute.
Ethically Favorable: Avoids the use of cadavers, addressing ethical concerns and reducing environmental impacts.
Integration of Imaging Techniques: Many platforms integrate radiographic, CT, and MRI images, which are vital for clinical practice.
Cons of Online/Virtual Anatomy Learning
Lack of Tactile Feedback: Virtual tools cannot replicate the feel, weight, and texture of real tissues, which may be crucial for understanding certain structures.
Reduced Realism: While detailed, virtual models may lack the complexity, variation, and imperfections seen in actual specimens.
Dependency on Technology: Requires reliable internet access and advanced hardware, which may not be universally available.
Cognitive Disconnect: Without physical interaction, some students may struggle to translate virtual learning into a real-world context.
Limited Problem-Solving Opportunities: Dissection often presents unforeseen challenges that hone practical skills and adaptability, which virtual platforms may lack.
Risk of Superficial Learning: Online tools may inadvertently encourage a less rigorous approach, focusing on memorization rather than deep understanding.
Rick’s Commentary
A blended approach - combining the hands-on experience of dissection
with the flexibility and interactivity of virtual learning –
offers the best of both worlds.
While online tools can serve as excellent supplements, the physical act of dissection remains invaluable for fostering a comprehensive understanding of veterinary anatomy and preparing students for the complexities of clinical practice. Institutions should strive to balance these methods, adapting them to students’ needs and ethical considerations.
