Ependymal cells:epithelial cells, they dialyse blood to make csf. Astrocytes: form the blood brain barrier, only let"s particular gases and nutrients in and out. Different than oligodendrocytes because they have many hands to make many myelin sheaths. Blood: t-cells, macrophages etc. helps get rid of pathogens. Neurons are postmitotic and gilia inhibit axon growth. Schwann cells promote axon growth (1mm a day) Neurons can sprout collaterals and regenerate (neurons that aren"t damaged can make their branches innervate target organs. you don"t get the exact same function back although you get most of it) Glia produce growth factors, glial cells help prevent cells from making new/weird connections) Diencephalon: inside the brain, where the hypothalamic sits.
