Organ identification rates and related factors during the dissection of chicken at the class of medical schools.

Abstract

During the dissection of a chicken (Gallus domesticus) performed at a medical junior college and a medical vocational school, no linear correlation was observed between the rate students were able to identify and observe the target organ (identification rate) and the distance (depth) from a section to the target organ, but was observed with the weight of the target organ. Such a correlation was more marked when the target organ weighed approximately 6 g or less. The linear correlation between the identification rate and that of students who had previously observed the target organ was higher than this. Furthermore, when the students who had previously observed the target organ accounted for 50%, the identification rate was highest if they had observed it in static images, followed by animated and actual images, in this order. Based on these results, in order to increase the identification rate, it may be appropriate to instruct students to pay attention to organs they have not previously observed in static, animated, and actual images, in this order, and lighter ones when the target organ weighs 6 g or less.
