DENDRITES CELL BODY AXON MYELIN SHEATH GLIAL CELL / GLIA NODE OF RANVIER

a cell that aids in the support of a neuron GLIAL CELL CNS PNS SCHWANN CELLS OLIGODENDROCYTE ASTROCYTE

wraps around the axon of neurons in the PNS multiple Schwann Cells in a row form the Myelin Sheath provides insulation -> action potential travels faster by jumping to the Ranvier nodes between Schwann cells SCHWANN CELL

a cell that aids in the support of a neuron GLIAL CELL CNS PNS SCHWANN CELLS OLIGODENDROCYTE ASTROCYTE

provides myelin insulation to multiple axons of neurons in the CNS OLIGODENDROCYTE

star-shaped glial cells that anchor neurons to their blood vessels plays an important role in the Blood Brain Barrier ASTROCYTE

semi-permeable membrane separating the brain from the blood helps maintain homeostasis for the brain protects the brain from foreign substances O 2, CO 2, glucose, alcohol, various hormones are among the few substances that can pass through the BBB BLOOD BRAIN BARRIER

Research: -Aneurysm -Alcohol Intoxication -Stroke -Multiple Sclerosis -Meningitis -Alzheimer’s Disease How does it affect neurons? -> What are symptoms? 2min Presentations Monday
