Hind brain
- Medulla
- Cerebellum
- Mesencephalon
- Thalamus and hypothalamus
- Cerebral cortex
Oligodendrocytes form myelin sheaths that protect one or more axons
Astrocytes are heavily branched cells attached to neurons that act as supply lines to absorb
and secrete things
Microglial cells monitor health of neurons can perform phagocytosis
Ependymal cells, typically ciliated, line the central cavities of the brain and spinal cord,
forming a barrier between cerebrospinal fluid and surrounding CNS cells
Blood vessel walls within the brain are not permeable. Molecules like oxygen and glucose
can. Endothelial cells in these blood vessel walls form tight junctions which is what restricts
the permeability.
