Nervous tissue - Describe the locations and functions of the various types of neuroglia

6 important questions on Nervous tissue - Describe the locations and functions of the various types of neuroglia

What are the four types of neuroglia in the central nervous system?

  • Astrocytes
  • Ependymal cells
  • Oligondrocytes
  • Microglia

What is the function of microglia?

Microglia remove cell debris, wastes, and pathogens by phagocytosis.

What are satellite cells?

Satellite cells surround neuron cell bodies in ganglia. They regulate the interstitial fluid around the neurons, much as astrocytes do in the CNS.

What are Schwann cells?

Schwann cells, or neurolemmocytes, either form a thick myelin sheath or intented folds of plasma membrane around peripheral axons in all parts of the peripheral nervous system.

List the neuroglia of the central nervous system.

  • Astrocyte
  • Oligodendrocyte
  • Ependymal cells
  • Microglia

Which type of neuroglia would increase in number in the brain tissue of a person with a CNS infection?

The small phagocytic cells called microglia occur in increased numbers in infected (and damaged) areas of the CNS.
