o B) The parasympathetic system and the sympathetic system
o C) The afferent system and the efferent system
o D) The somatic motor nervous system and the autonomic nervous system
2. The ANS can be affected by conscious thought but it cannot be controlled by
conscious thought.
o True
o False
3. Both the somatic nervous system and the autonomic nervous system are
involuntary.
o True
o False
4. The somatic nervous system does not have inhibitory capabilities.
o True
o False
5. The sympathetic division
