What do we need to know about nerve tissue?
The nervous system contains nerve cells and glia cells. While glia cells serves the function of nutrition and immune response within the nervous system, nerve cells (also called neurons) are information processing devices. The architecture of each neuron is rather uniform. It consists of the cell body, the dendrite and the axon. The cell body (soma) contains the nucleus of the neuron and is, thus, the site of gene expression and protein synthesis. The main pathways are…
