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.
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
Astrocytes and oligodendrocytes originate from neuroepithelial cells in the developing nervous system. Astrocytes arise from radial glial cells, which serve as neural stem cells, while oligodendrocytes are derived from oligodendrocyte precursor cells (OPCs) that migrate from the germinal zones. Both cell types play important roles in supporting and protecting neurons in the brain and spinal cord.
astrocytes in the brain. Astrocytes take up glucose and convert it to lactate, which is then released and used as an energy source by neurons. This process is known as the astrocyte-neuron lactate shuttle.
Specialized supporting cells in the central nervous system (CNS) include astrocytes, oligodendrocytes, and microglia. Astrocytes provide metabolic and structural support, oligodendrocytes produce the myelin sheath that insulates nerve fibers, and microglia are involved in immune responses and maintaining the health of the CNS.
Another name for neuroglial cell is glia cells, or supporting cells. Here are some examples. There are three types of glial cells in the mature central nervous system: astrocytes, oligodendrocytes, and microglial.The supporting cells of the Peripheral Nervous System are known as Schwann Cells.
Microglia function as phagocytes.

Astrocytes (glial cells hence the glue)
Astrocytes anchor neurons to blood vessels!

no but ependymal cells does
The four types of neuroglia in the central nervous system (CNS) are astrocytes, oligodendrocytes, microglia, and ependymal cells. Astrocytes provide structural support and regulate the chemical environment, oligodendrocytes produce myelin to insulate axons, microglia are the immune cells of the CNS, and ependymal cells line the ventricles and produce cerebrospinal fluid.
The most abundant neuroglia in the central nervous system is the astrocyte. Astrocytes provide structural support to neurons, help regulate the extracellular environment, and play a role in the blood-brain barrier function. They also contribute to the repair and scarring processes in the brain and spinal cord after injury.
