The approach to the study of human anatomy is the subject of discussion by teachers and students. Nowadays, the debate revolves around the use of cadaveric material or it's relacement with virtual technologies. It questioned how necessary is the use of preparations, the efficiency of the virtual plataforms, the cost-benefit relation, their limitations and if they would replace the cadaveric material or if they would be a complement. Traditionally, dissections are exposed in tables during practical works. Observing a persistent year through year increment in the number of entrant students to Medical School and considering the inconveniences in the attainment of dissecting material and the diminished durability of the preparations due to extensive and not always careful manipulation, the proposal for the creation of interactive bottled preparations arises organically. When they are engaged, their durability increases, while, being interactive, the capacity for indirect manipulation is maintainded. In addition, the degreee of contamination is considerably reduced because the bottle, being sealed, prevents the emission of toxic gases generated by the evaporation of formaldebyde acid, preventing direct exposure. Another questioned axis in the scientific field is the ethical aspect of the use of cadaveric material as a pedagogical tool. In opposition, the preparations fulfill the role of representing the first approach of the student with his patient, understanding that it is not an object-machine but that it is a person, being his firts physical contact with death, taking it as a biological fact. Subsequently, the individual will relate to his real patient with a greater sensitivity and a more humanitic approach
