Across
  1. 1. produce myelin sheaths that insulate the neurone and increase the speed of nerve transmission in the CNS
  2. 3. provide structural support to neurones and regulate the EXC environment by maintaining the blood-brain barrier and ion balance. They can also supoort synapse formation
  3. 4. they provide support and nutrition to neurones in the PNS
  4. 6. these act as the immune cells of the CNS and defend against pathogens and remove cellular debris
  5. 7. the cavities of the brain where CSF rests
  6. 8. produce myelin sheaths that insulate the neurone and increase the speed of nerve transmission in the PNS
Down
  1. 2. they are found in the ENS of the digestive tract, regulate digesttive processes and interactions with gut microbiota
  2. 5. line the cavities of the brain and the spinal cord and produces cerebrospinal fluid which provides cushioning/nutrition for the CNS
  3. 9. the cavity within the vertebrae wherein CSF is transported to provide nutrients to the spinal cord
