Model of brain & spinal cord
Реферат: 173,684. Brook, T. Dec. 7, 1920. Models. - A model of the human brain and spinal cord, showing the inner constituents and nerve connections, is made of steel wire and wire mesh sections constructed from enlarged tracings of the structures seen in successive sections of a brain. The sections are fixed in their relative positions and show the outer configuration of the central nervous system and its inner constituents, each considerable structure being labelled. The nerve fibres are represented by strings of distinct colours threaded through the sections. Fig. C shows a typical section modelled from a brain section near the occipital pole and behind the splenium. The sections may be cast in metal. An electric bulb may be placed within the model.
