Background and Aim: Teaching human anatomy, at any level, relies not only on the expertise of a tutor but also on the availability and use of good teaching aid. Plastination specimens have unique position as a teaching aid to exhibit accurate anatomical structures and easy to be stored and handled by students. The aim of this study was to prepare plastinated specimen of trunk, by Survey of vessels color ability rate via colored polymer in S10 plastination technique. Materials and Methods: This study performed on a human body after fixation of the cadaver .The colored polymer was prepared by mixing red colored paste with polyester and the cobalt (accelerator) and peroxide (hardening material) was added to it. The prepared colored material was injected into the body through femoral artery by the naso-gastric catheter with the help of the hydraulic pump. After a few days when the colored polymer dried up, dissection (Posterior trunk, spinal cord and medulla oblongata), dehydration, defatization and impregnation of the body was carried out. Finally the prepared plastinated specimen was compared with the standard plastinated model. Results: The prepared plastinated specimen was dried, in toxic and without noxious fumes also spinal cord and medulla oblongata have showed a normal anatomical position of structure and flexibility, elasticity and traction was compared with a similar one of standard specimen. The obtained result showed that the P-value was 0.05 and the standard error was (0.382±-0.4600). Colored polymer into the arteries and colored vein was easy for detection. Conclusion: According to this study, the P-value was greater than 0.05, which shows no significant difference statistically. The plastinated specimen prepared by injecting colored polymer into the arteries, provided an excellent opportunity to demonstrate and reduction in toxic and noxious fumes of formalin, durability and safety.
