Clues

  • A neuron which carries messages from the PNS to the CNS (7)
  • A neuron which connects sensory neurons to motor neurons (5)
  • A neuron which connects the CNS to effectors such as muscles and glands (5)
  • At the end of the axon that communicate with the next neuron in the chain across the synapse (8, 6)
  • Branch-like structures that protrude from the cell body (9)
  • Chemicals that diffuse across the synapse to the next neuron in the chain (17)
  • Each neuron is separated from the next by a tiny gap (7)
  • Fatty layer that protects the axon (6, 6)
  • Gaps in the axon which speed up the transmission of the impulse (5, 2, 7)
  • Includes a nucleus which contains the genetic material of the cell (4, 4)
