Inside CNS
cell bodies derive from neural tube
Cell bodies outside CNS
PNS=ganglia (neural crest cells)
Glial tissue (inside CNS)
Astrocytes (neural tube)
Olygodendrocytes
myelination inside CNS (neural tube)
Schwann cells
myelination PNS
neural crest cells
Spinal cord-ventral root
Motor fibers-neural tube
Spinal cord- Dorsal root
sensory- neural crest cells
Microglial cells
cleaning CNS (phagocytosis) from Mensenchyme
Mesenchyme
Meninges -Dura mater
Arachnoid and Pia
Leptomeninges (neural crest cells)
Astrocytes
- clean excess K+ in extracellular, also neurotransmitters
- Blood brain barrier
- form scar tissue inside CNS
