Document Summary
*the gap between the terminal button and the receiving membrane is know as the synaptic cleft. Glia, the support cells of the nervous systems. Critical in immune response in the nervous system. Serve as microphages - eat and destroy other cells (foreign substances, diseases, etc. ) Located specifically in the central nervous system (also the most abundant). Provide physical support for neurons as they create a matrix that holds neurons in place. Connect to blood vessels in the brain, acquire glucose, either store the glucose or turn it to lactate, ultimately providing nourishment to neurons. Control chemical composition of fluid surrounding neurons. Astrocytes keep viruses and drugs and toxins out of the brain but allow nourishing elements in. Schwann cell - myelinating glia located in the peripheral nervous system. Oligodendrocytes - myelinating glia in the central nervous system. Can myelinate different axons of different neurons. Causes coordination and motor problems due to pathways of the nervous system working at different speeds.
