Description

technical field

[0001] The invention belongs to the technical field of teaching aids for embryology, and in particular relates to a teaching aid for the occurrence of atrial septum in embryology, and also relates to a method for using the teaching aid. Background technique

[0002] The development of atrial septum is an important part of the teaching content of cardiogenesis in "Embryology". The study of the process of atrial septal development is the theoretical basis for clinical diagnosis and treatment of atrial septal defect. At present, in the teaching of atrial septal occurrence, teachers mainly demonstrate through pictures and animations. However, due to the large number of professional terms in this content, especially involving the dynamic development and evolution of various structures and the changes in their mutual positional relationship, students often express difficulty in understanding, which affects learning result.
