Document Summary
* a neuron connects with another neuron via its synapse (7) from its axon terminal usually to a dendrite. Neurons are myelinated to change the speed of action potential conduction via oligodendrocytes in the central nervous system (1) and schwann cells in the peripheral nervous system. * blood vessels (8) are an integral part of the brain. The brain is totally reliant upon continual supply of oxygen and nutrients and without that blood supply the brain will shut down very quickly, hence the blood supply is essential for neuronal function. * glia glia comes from the term for glue were first discovered as the cells that were thought to hold the brain together (a structural role). Most of the time we are talking about glia we are talking about astrocytes (6), but there are multiple different type of glia including oligodendrocytes. * an astrocyte has a reasonably large cell body (shown in green).
