<p>A model of the human head is intended for use in biology, organics lectures and uses transparent plastics elements. The model is in the form of a two dimensional cross sectional view through the head. A main sheet of plastics is of A4 size and contains a second layer formed to the shape of the head. The skull is represented by a different coloured material and all moving parts e.g. the jawbone are formed by pinning.</p> |
