Glial Cells Flashcards
Function of nerve cells or neurons?
Responsible for the transfer and processing of information in the nervous system
Function of supporting cells or neuroglia?
Support and isolate the neurons
The 3 functions of neuroglias is?
- Providing the framework for the neural tissue
- Maintaining the intercellular environment
- Acting as phagocytes
What are the names of the 6 classifications of neuroglia?

True
T/F
Astrocytes are the largest and most numerous glial cells.
True
What are the functions of the astrocytes?
- Maintaining the blood-brain barrier.
- Creating a 3-D framework for the CNS
- Performing repairs in damages neural tissue
- Guiding neuron development
- Controlling the interstitial environment
T/F
Oligodendrocytes produce myelin sheath in PNS.
False. They produce myelin sheath in the CNS.
