Zoological models and educational zoology models

	ZoS 54/1 - Models of the Hearts of Vertebrates Separable, made in SOMSO-Plast®. The internal structure is shown in all its detail, the direction of the blood flow is marked. Altogether 7 models, in natural size and slightly enlarged, individually mounted on a stand with base. 1. Fish (Esox lucius), 2. Frog (Rana esculenta), 3. Tortoise (Emys orbicularis), 4. Crocodile (Crocodylus niloticus),, 5. Bird (golden eagle) - (Aquila chrysaetos), 6. Dog (Canis lupus familiaris) and 7. Human Being (Homo sapiens). Altogether 14 parts.

	ZoS 58 - Equal Cell Division and the Formation of the Nuclear Membrane in the Branchiostoma Lanceolatum Amphioxus, Lancelet, model enlarged approx. 500 times, made in SOMSO-Plast®. Nine models (A - J) on stands with bases show the various stages in cell division, the formation of the blastula and original membrane. Model in one piece.

	ZoS 59 - Lancelet Branchiostoma lanceolatum, model enlarged approx. 150 times, made in SOMSO-Plast®. The 4 models (K - N) show the formation of the nuclear membrane in the larva of the lancelet and its final structure in longitudinal and cross section. Individually mounted on a stand with base.

	ZoS 101/1- Globorotalia menardii Original size 0,5 mm ø, made in SOMSO-Plast®. Model in one piece.

	ZoS 103 - Structure of Chicken's Egg The model shows an unincubated, fertilised chicken's egg, model enlarged 6.5 times linearly, made in SOMSO-Plast®. Model in one piece, on a stand and base with explanatory notes. Height: 43 cm., width: 39 cm., depth: 26 cm., weight: 3.5 kg

	ZoS 103/1 - Germinal Disc of a Fertilised but Unincubated Egg The model shows the germinal disc in the stage of the formation of the yolk membrane - linearly enlarged 70 times, made in SOMSO-Plast®. Model in one piece, on a stand with base.

	ZoS 103/2 - Chicken's Embryo After approx. 20 Hours Incubation This separable model shows a section of the membrane enlarged 56 times linearly, made in SOMSO-Plast®. Model separates into 4 parts, on a stand with base.

	ZoS 103/3 - Chicken's Embryo After Approx. 33 Hours Incubation enlarged 53 times linearly. In SOMSO-Plast®. A concentric part of the embryo can be removed from the yolk, Somites and chorda are visible through a ventral window. Model separates into 2 parts, on a stand with base.

	ZoS 103/4 - Chicken's Embryo After Approximately 50 Hours Incubation enlarged 54 times linearly. In SOMSO-Plast®. The embryo separated from the vitelline mass shows the changes of position caused by the bending of the neck and turning of the anterior body. Model in one piece, on a stand with base.

	ZoS 103/5 - Chicken's Embryo After Approximately 4 Days Incubation enlarged 45 times linearly. In SOMSO-Plast®. The embryo opened on the right gives a general view of the detailed regions of the central nervous system and the structure of the cerebral nerves. Model in one piece, on a stand with base.
