Astrocytes - CNS - Supply nutrients to neurons - Surround blood capillaries - Transmit information
Microglia - CNS - Immune cells of the CNS - Engulf microorganisms and debris
Ependymal cells - CNS - Line fluid-filled spaces of the brain and spinal cord - Cilia circulate cerebrospinal fluid
Oligodendrocytes - CNS - Nerve fibre support - Provide myelin to the neurons
Schwann cells - PNS - Support peripheral nerve fibres - Provide myelin - Similar to oligodendrocytes in the CNS
Nodes of Ranvier - Gaps between myelin - Increase conduction speed
Neurilemma - Only in PNS - Where the Schwann cells nucleus and cytoplasm are pushed to the perimeter of the cell
Axodendritic synapse
Axosomatic synapse
Axoaxonic synapse
Somatic Voluntary
