What are the two main cells of the brain?
Generally, these would be the neurons and the supportive cells. Supportive cells, however, comprise several different kinds of cells. These include oligodendrocytes, glial cells, schwann cells, astrocytes, etc.
Why can the peripheral nervous system heal but the central nervous system can't?
the schwann cells (supportive cells) in the peripheral nervous system allow the neurons to regenerate, while the supportive cells in the central nervous system (oligodendrocytes and astrocytes) prevent neuron regeneration.
What two cells form the insulating sheaths around axons?
Schwann cells and oligodendrocytes
Neuroglial cells that are star-shaped are called?
Astrocytes
What cells cover the outer surface of the CNS?
Astrocytes.
How do Schwann cells and astrocytes differ?
A+ Students - myelin sheath A Schwann cell is a particular type of neuroglial cell, found only in the peripheral nervous system. Schwann cells produce the myelin sheath, which insulates the axons of bodily nerves, increasing the signal velocity.
What are the types of neuroglia?
There are 6 different types CNS: astrocytes, microglia, ependymal, and oligodendrocytes, PNS: satellite cells, and schwann cells
Examples of neuroglial cell?
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.
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

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!

Schwann cells and oligodendrocytes
