Glial Cells Flashcards
What glial cells are found in the CNS?
Astrocytes
Oligodendrocytes
Microglia
Ependymal cells
What glial cells are found in the PNS?
Schwann cells
Satellite cells
These cells maintain the extracellular environment, remove excess neurotransmitter, direct neural growth, and maintain the blood brain barrier
Astrocytes
These cells maintain the extracellular environment, remove excess neurotransmitter, and direct neural growth in the PNS
Satellite cells
These cells myelinate CNS neurons
Oligodendrocytes
These cells myelinate PNS neurons
Schwann cells
These cells are involved in immune activity and phagocytosis in the CNS
Microglia
These cells create and circulate CSF
Ependymal cells
What do astrocytes do to blood vessels in the brain?
Tighten cell junctions in the walls of the vessel to prevent substances from diffusing into the brain from the blood
What structure in the ventricles of the brain is created by ependymal cells?
Choroid plexus
This structure surrounds blood vessels in the ventricles of the brain to filter blood into CSF
Choroid plexus
What differs oligodendrocytes from Schwann cells?
Oligos are in the CNS and have processes that myelinate multiple cells; Schwanns are in the PNS and only surround a portion of a single neuron axon
