Glial Cells Flashcards
What are oligodendrocytes?
Provide myelination in the CNS
Oligodendrocytes are a type of glial cell that wrap axons in the central nervous system with myelin, facilitating faster signal transmission.
What is the function of Schwann cells?
Provide myelination in the PNS
Schwann cells are responsible for myelination of peripheral nerves, ensuring efficient nerve signal conduction.
What role do astrocytes play in the CNS?
Provide various support functions to neurons in the CNS
Astrocytes maintain the blood-brain barrier, provide nutrients to neurons, and support overall brain architecture.
What do ependymal cells produce?
Cerebrospinal fluid in the CNS
Ependymal cells line the ventricles of the brain and the central canal of the spinal cord, helping to produce and circulate cerebrospinal fluid.
What is the function of satellite cells?
Control the microenvironment around cell bodies in ganglia in the PNS
Satellite cells provide structural support and regulate the chemical environment of neurons in peripheral ganglia.
What are microglia?
Similar to Macrophages, that clean out microbes and debris in the CNS
Microglia act as the immune cells of the central nervous system, responding to injury and disease by removing waste and pathogens.
What are glial cells?
Supportive cells in the nervous system
Glial cells, or neuroglia, are non-neuronal cells that provide support, nourishment, and protection for neurons.
