1. When I saw the title of the exhibition, I thought it was youth education with pictures and words, knowing the body, understanding the gender differences, and educating myself to care for myself. Who knew it was so fierce!

2. It looked strange at first, but I looked very carefully, especially the organs and tissues, which were integrated with the junior high school science pictures and looked very difficult. Baby specimens are not so terrible, and it is impossible to restore them if you think about it. It is certain that they are all true.

3. But then I was really scared to see the skeleton and the general teacher, and I also saw the face under the stockings. Gee, I remember very clearly ... The specimens were all stitched, cut and bruised, so it must be true.

4, so, adolescent children, don't watch this exhibition, I am in college, and I am still a little scared after reading it. Who can withstand this visual impact in adolescence?

Stripped sample

The muscles, bones, viscera and subcutaneous fat of animal remains were completely hollowed out, leaving only fur, scales and horns on the body surface. After tanning fur, put on 1: 1 animal "prosthesis" made of resin, gypsum or glass fiber reinforced plastic to make plump specimens, which are mainly used for mammals, birds and some large reptiles that are not suitable for making soaking specimens.

Mold sample

Plastic materials are injected into animal cavities, and after curing and molding, redundant tissues and organs are removed, leaving only specimens made of fillers (like peeling cakes). The shape is vivid and intuitive, which fully shows the true shape of cavities in animals (such as cardiovascular, digestive, respiratory and urinary system cavities and bird airbag cavities). ), and organs can be distinguished by color and can be preserved for a long time. This is an important method to study the morphological structure of animal lumen.

Plasticized sample

Fresh animal carcasses were soaked in formalin for disinfection, then soaked in acetone solution for dehydration and degreasing, and acetone in tissues was replaced by liquid epoxy resin and silicone rubber, and then the specimens were shaped and solidified by spraying curing agent for many times, so that the animal tissues and organs and the overall shape could still be kept in the original state. Because the material has changed from organic matter to "plastic", the plasticized specimen can be preserved for a long time.

Transparent specimen

Filling agents are injected into the tubes, cavities and sinuses of animal organs to make the tissues transparent, and at the same time, the internal morphological structure and blood supply characteristics of the organs are clearly and intuitively displayed while maintaining the appearance integrity of the organs. In the actual operation process, the casting mold and transparent specimen making process are often combined to make transparent specimens.
