Teaching aid for arterial trunk separation in embryology and using method of teaching aid

Abstract

The invention discloses an embryology arterial trunk separation teaching aid and a using method thereof. The embryology arterial trunk separation teaching aid comprises three arterial trunk bodies of the same structure, wherein a side wall of each arterial trunk body is symmetrically provided with a group of notches a, and a normal aorta pulmonary arterial septum group can be inserted into the arterial trunk body through the notches a; the normal aorta pulmonary artery septum group comprises two opposite normal aorta pulmonary artery septum, and further comprises a silk ribbon a and a silk ribbon b, and the silk ribbon a and the silk ribbon b are arranged on two sides of the normal aorta pulmonary artery septum group respectively; the abnormal aorta pulmonary artery septum group and the offset aorta pulmonary artery septum group can be inserted into the arterial trunk body, and the abnormal aorta pulmonary artery septum group is used for demonstrating the flowing path of aorta and pulmonary artery blood flow under the condition of aorta and pulmonary artery malposition and malformation; the offset aorta and pulmonary artery septum group is used for demonstrating the flowing path of aorta and pulmonary artery blood flow under the condition of aorta or pulmonary artery stenosis deformity.

Description

technical field [0001] The invention belongs to the technical field of teaching aids for embryology, and specifically relates to a teaching aid for arterial-trunk separation in embryology, and also relates to a method for using the teaching aid. Background technique [0002] Arteriosepsis is an important part of the teaching content of cardiogenesis in "Embryology". The study of the development process and results of arteriosus is the theoretical basis for clinical diagnosis and treatment of arteriosepsis. At present, in the teaching of arteriosclerosis development, teachers mainly demonstrate through pictures and animations. However, due to the large number of professional terms involved in the content, it involves the dynamic development and evolution of various structures and the change of their mutual positional relationship, which requires a certain degree of spatial imagination. Therefore, Students often express difficulty in understanding, which affects the learning e...

At present, in the teaching of arterial trunk development, teachers mainly demonstrate through pictures and animations. However, due to the large number of professional terms in this content, which involves the dynamic development and evolution of various structures and the change of mutual positional relationship, a certain degree of spatial imagination is especially required. Students often express difficulty in understanding, which affects the learning effect
