Astrocytes are star shaped glial cells because of cytoplasmic processes that extend from the cell body.
They play a role in regulating the extracellular composition of brain fluid. They release chemicals that promote the formation of tight junctions between the endothelial cells of capillaries.

Four types of neuroglia in the cns?
The four types in the CNS are microglia, astrocytes, ependymal, and oligodendrocytes. *microglia= phagocytes *astrocytes= form the blood brain barrier *ependymal= produce CSF (cerebral spinal fluid) *oligodendrocytes= form the myelin sheath that wraps around the axon
The production and release of lactate to provide energy to the neurons is a function of the?
astrocytes
Function of stellate reticulum?
Stellate only means that its cytological appearance is that of a star. Astrocytes (astro- means 'star' as well as stella--I think of stellar) are stellate cells, but so are Kupffer cells.
What cells remove neurotransmitters from receptor sites?
Cells known as astrocytes can remove neurotransmitters from the receptor area.
Specialized supporting cells in the CNS?
The neuroglia ("nerve glue"), or glial cells, which in the CNS include Astrocytes, Ependymal cells, Microglia, and Oligodendrocytes.
What neuroglial cell has phagocytes?
Microglia function as phagocytes.
What are the four types of glial cells?
astrocytes, microglia, ependymal, and oligodendrocytes.
What are found in the CNS and act as the glue that binds axons and blood vessels to each other?
Astrocytes (glial cells hence the glue)
What type of cells anchor neurons to blood vessels?
Astrocytes anchor neurons to blood vessels!
What are the four types of neuroglia in the CNS?
Astrocytes, Microglia, Ependymal cells, and Oligodendrocytes
What cells cover the outer surface of the CNS?
Astrocytes.
Neuroglial cells that are star-shaped are called?
Astrocytes
What would happen if the glial Cells stopped working?
Glial Cells and Astrocytes provide the bi-Cellular support structures that maintain and support Neuronal tissues. Neurons would cease to function.
Astrocytes line the central cavities of the brain?
no but ependymal cells does
