Document Summary
Chapter 2: neurons and glia: tissues and organs are made up of cells. These cells determine the organ function: there are two types of cells in the nervous system, neurons, glia (both are broad categories) They are both roughly equal in capacity with roughly 80 billion of both present in the body. Neurons sense changes in the environment and respond to them. Glia insulate and support neighboring neurons: think of them as the glue that suspends neuron cells. Histology is the study of the structure of tissues: color coding of brain tissue cells: The nissl stain was developed to distinguish neurons from glia. It allows others to study cytoarchitecture, or the neurons of different areas of the brain. The golgi stain is developed by soaking sections of the brain in chromate. It reveals that the cell is much longer and complex than originally suspected.
