CNS Neuroglia
What is an astrocyte?
What are satellite cells?
What is membrane potential?
These CNS neuroglia wrap the axons of CNS neurons with myelin.
What are oligodendrocytes?
These neuroglia form a myelin sheath around peripheral axons.
What are Schwann Cells?
The ion that causes depolarization in the process of an AP.
What is Na+ (sodium)?
These neuroglia are phagocytic and act like janitors.
What are microglia?
Clusters of cell bodies that surround neurons.
What is a ganglia?
The ion that causes repolarization.
What is potassium (K+)?
These neuroglia produce CSF and live in the central canal of the spinal cord.
What are ependymal cells?
These neuroglia release growth factors and basal lamina for regenerating nerves.
What are Schwann Cells?
The amount of mV that cause the membrane to reach threshold.
-55 mV
These neuroglia maintain the blood brain barrier.
What are astrocytes?
The name of the outer surface of a Schwann cell.
What is neurolemma?
The local change in membrane potential that spreads across a small region of the neuron and then stops.
