Organization of the nervous system
A nerve trunk comprises many single neurones (nerve cells). Thus, the nerve cell is the basic constituent of the nervous system (figure 1.1) and there are some 1 × 1012 neurones in the human nervous system. The neurone comprises three distinct portions, the cell body, the axon and the nerve terminal.
