Across
  1. 2. The type of neuron that receives information from the muscles and organs within the body and transfers the messages to the central nervous system.
  2. 5. Combines the information from the neuron's many dendrites and sends it down the axon.
  3. 7. A thin extension of the cell that receives information from other cells.
  4. 8. The entire network of nerves located outside the central nervous system.
  5. 10. The nervous system that sends messages between the CNS and the internal muscles and organs to regulate automatic functions.
  6. 11. The nervous system consisting of the spinal cord and brain.
  7. 12. The thin, tube-like part of a neuron that transmits the neural information from the soma down to the axon terminals.
  8. 14. The nervous system responsible for carrying sensory messages to the CNS and motor messages from the CNS.
  9. 16. Callosum, the band of nerves that connects the left and right hemisphere.
  10. 17. ____________________ specialisation: the understanding that the left side of the brain controls different functions to the right side.
  11. 18. The type of neuron that only exists in the central nervous system.
  12. 19. The lobe of the brain responsible for planning, organisation, goal setting and personality.
  13. 20. The lobe of the brain responsible for processing visual information.
Down
  1. 1. An individual nerve cell that receives, processes and/or transmits information to other cells.
  2. 3. The main feature of this lobe is memory. It also contains the Primary Auditory Cortex.
  3. 4. ______________ sheath: protects the axon and enables the message to pass quickly from the soma to the axon terminals without interference from other neurons.
  4. 6. The long, thin bundle of nerve tissue that extends from the base of the brain to the lower back.
  5. 9. Primary __________________________ Cortex which is responsible for touch sensations. More space is allocated the the sensitive areas of the body.
  6. 13. The type of neuron that transfers the message from the central nervous system to the skeletal muscles to cause movement.
  7. 15. Axon _______________________ are small branches at the end of a neuron that contain neurotransmitters, which are released into the synaptic gap and are received by another neuron's dendrites.
