6. What system is made up of the neurones that carry impulses into and out of the CNS?

  • The Peripheral Nervous System
  • The Central Nervous System

7. Which sub-division of the Peripheral Nervous System carries impulses from the CNS to cardiac muscle

  • The Autonomic Nervous System
  • The Somatic Nervous System

8. Which sub-division of the Autonomic Nervous System is most active during times of relaxation?

  • The Parasympathetic Nervous System
  • The Sympathetic Nervous System

9. Which is the true statement about the Parasympathetic Nervous Systemt?

  • Ganglion are in target tissue so pre-ganglionic neurones are very long
  • Ganglion are in target tissue so pre-ganglionic neurones are very short
  • Ganglion are just outside the spinal cord so pre-ganglionic neurones are very short
  • Ganglion are just outside the spinal cord so pre-ganglionic neurones are very long

10. Which of these is a similarity between Synapses and Neuromuscular Junctions?
