Creating new embryological models for teaching cardiac development in embryology

Area of Science:

• Embryology
• Anatomy
• Medical Education

Background:

• Embryology, particularly human heart development, is complex and challenging to teach using traditional 2D methods.
• A 3D understanding is crucial for grasping embryological concepts, yet resources are often limited.
• Traditional methods hinder comprehension of intricate developmental processes like cardiac formation.

Purpose of the Study:

• To develop and present a series of physical models illustrating key stages of human heart embryology.
• To provide supplementary educational tools for students learning complex embryological development.
• To improve the understanding of both normal heart development and associated pathologies.

Main Methods:

• Utilized Polydoh moldable plastic to create physical models.
• Modeled six critical stages of human heart formation, from initial tube fusion to septation completion.
• Included stages such as cardiac looping, four-week development, and the formation of septa and the foramen ovale.

Main Results:

• Successfully created a series of six distinct 3D models representing key embryological heart development milestones.
• Demonstrated the utility of these models in supplementing traditional embryology curricula.
• Validated the models as effective tools for enhancing student comprehension of cardiac development.

Conclusions:

• 3D physical models offer an effective and affordable method to enhance embryology education.
• These models improve student understanding of complex organogenesis, specifically human heart development.
• The tactile learning approach aids in visualizing intricate anatomical changes and can inform the study of congenital heart anomalies.
