Abstract

A model of a living body includes a cranium as a main body; and organ components (tongue portion and ear portion) made of yieldable material, arranged on the main body, wherein an external force is applied to one of the organ components from the external of the main body to deform the organ component, and thereby the inside of the organ component can be observed from the external of the main body.

Claims

1. In an anatomical model including a main body comprising a hollow cranium portion, a mouth opening, a lower jaw portion, and a tongue portion located within said cranium portion inside of a mouth portion of said main body, the inner end of said tongue portion being attached to said lower jaw portion, the improvement wherein said tongue portion comprises a yieldable outer layer of silicone rubber and a yieldable inner body of silicone gel covered with said outer layer, a transversely extending guide rod attached to said cranium portion adjacent said lower jaw, said tongue portion extending upwardly from said lower jaw and outwardly over said guide rod toward said mouth opening whereby when an external force is applied to said tongue portion by grasping the outer end of said tongue, said tongue portion is yieldably deformed to reduce its cross section and is slideably guided by said guide rod, whereby said tongue portion and interior cranium portions can be observed from the exterior of said cranium portion.

2. A model according to claim 1 including an ear portion comprising a concha portion and a tubular portion formed integrally with said concha portion, said tubular portion being inserted into an opening of said main body and fixed to said main body.

3. A model according to claim 1 including a nose portion fixed to said main body.

4. A model according to claim 1, in which said main body is covered with at least one integument portion.

5. A model according to claim 4, in which said main body comprises polyester resin, and said integument portion comprises silicone rubber.
