Plastination is a special technique with which people can preserve biological tissue as it is alive. The high-tech solid preservation method has all the advantages of traditional preservation methods and discards their deficiencies, so it overwhelms all the other methods. In this technique, a vacuum physical process is applied, the water and fat in biological tissue are replaced by high-molecular polymers such as silicone rubber, epoxy resin and polyester resin through an impregnation process. The finished animal specimens are non-toxic, odorless, dry, resilient, portable and durable, without the requirement for special maintenance or protection. In addition, they can not only keep the original shape and appearance of the animals(fur, etc.) but also show their interior structure, vividly presenting the various postures of animals as they are alive.
Superficial arteries of hand plastination specimen clearly shows radial artery, ulnar artery, superficial palmar arch, common palmar digital arteries, proper palmar digital artery, lumbrical, abductor pollicis brevis, abductor digiti minimi, etc.
Half head plastination dissected sagittally, includes the whole neck and 1st rib.Those parts have been removed: the lateral wall of the cranial cavity, the zygomatic arch and the mandible.
Half head plastination specimen cut sagittally.superficial dissection displays the muscles of facial expressions,arteries and nerves and the salivatory glands from the lateral aspect.Neck shows the structures within its triangles.
