Glial cells are also known as neuroglia which means "glue"
what are some of the functions of glial cells? For support. Supply nutrients and oxygen to neurons. Insulation. Kill pathogens and remove dead neurons
Do neuroglia conduct nerve impulses? Neuroglia do not generate nerve impulses
Can glial cells regenerate if injured? YES, glial cells can regenerate if injured unlike neurons
what are glial cells glial are specialized cells that nourish and support neurons
what are satellite glial glial cell that provide nutrients for neurons in the PNS
what are astrocytes cells a neuroglial cells in the shape of a star in the brain
what are radial glial this are glial cells that act as a bridge for developing neurons as they move to their end destination
what are schwann cells the only glial located in the PNS. myelination of axons
what are microglia cells in the brain that function as phagocytes to remove debris left by dead or degenerating neurons and glial cells
what are oligodendroglia glia that provide layers of membrane that insulate axons in the brain and spinal cord, able to contribute myelin to several axons
what are basal ganglia basal ganglia is a structure of the brain that plays a role in the initiation of movements.
what are radial glia direct neurons during development
what are the four types of CNS neuroglia cells? Astrocytes, Ependymal cells, microglial cells, Oligodendrocytes
Where does Astrocytes get their name from? their name come from the fact that they look like a star
Where are Astrocytes mostly found? Astrocytes are mostly found in the brain
The Astrocytes cell body sites between the _______ and _____ of the brain between the blood capillary and neurons of the brain
What are the function of Astrocytes? They function as the blood brain barrier
How do Astrocytes behave as blood brain barriers?, They regulate the flow of ions, sugars and oxygen in and out of neurons. Also regulate waste elimination
When neurons in the brain are injured they are replaced with scar tissue made up of ______ Astrocytes in a process called gliosis
what is the function of oligodendrocytes? Oligodendrocytes are responsible for myelination of axons within the CNS
where are Oligodendrocytes found? Oligodendrocytes are found in the nervous system of invertebrates and vertebrates. Also in rows between axons
Oligodendrocytes are subdivided into ________ and _______ they are subdivided into interfascicular and perineuronal types
How can Oligodendrocytes be diferenciated from astrocytes? Oligodendrocytes have a greater density of cytoplasm and nuclear, large numbers of microtubles
what kind of cells are Ependymal cells? They are cells that line the cerebral spinal fluid containing cavities of the brain
what are Ependymal cells? They are neuroglia cells that form epithelial lining of ventricles in the brain and spinal cord
what is the function of satellite cells? They regulate the oxygen, carbon dioxide, and nutrients around neurons in ganglia
what is the function of schwann cells? They help in the repair process after injury. Also responsible for myelination of peripheral axons
where are schwann cells found? They surround axons in the PNS
Schwann cells create?, nodes of ranvier
what is the function of nodes of ranvier? they allow electrical impulses to jump from one node to another faster than unmyelinated neuron
what is the function of microglia? They perform housekeeping functions.They remove cell debris. Remove pathogens and phagocytosis. Remove dead cellular materials and bacteria
What kind of cells are Microglia? they are phagocytic cells similar to macrophages
Microglia cells are also known as? mesoglia
where do microglia originate from? They originate from the bone marrow and enter the CNS through the blood
when are microglia activates? Microglia are present in small numbers, but proliferate and activate if there is a disease or injury
