Cells of the Nervous System

HideShow resource information
Glial
The most abundant cell types in the CNS. They're supportive cells - they do not conduct electrical impulses
1 of 7
Neuron
Cells that conduct electrical impulses - signalling cells
2 of 7
Astrocyte
These cells have numerous projections that link neurons to their blood supply while forming the BBB. They signal each other via gap junctions. They move around K+ ions to ensure the correct environment for action potentials (spatial buffering)
3 of 7
Oligodendrocyte
These cells myelinate multiple axons in the CNS - important for fast, efficient signalling
4 of 7
Schwann cell
These cells myelinate one axon in the PNS. They have an outer neurolemma (cytoplasm on the outer layer of the cell)
5 of 7
Microglia
Phagocytic cells involved in the immune system
6 of 7
Ependyma
These cells line the ventricular system. They are ciliated to waft away cerebrospinal fluid which circulates around the brain and down the spinal cord
