The Nervous System chart is an overview of one of the most complex system of the human body. The central image of the chart shows the brain and the major nerves of the body. The cranial nerves, spinal structure, functional brain areas and the neuron and synaptic cleft are shown through other images. Heavy gauge 3ml lamination with sealed edges and two metal eyelets for hanging makes chart highly durable. Write-on/wipe-off with dry erase marker (not included).
