    • What part of the nervous system does the autonomic nervous system belong to?
      Peripheral nervous system
    • What organs does the autonomic nervous system supply?
      Internal organs like heart and lungs
    • How does the autonomic nervous system operate?
      Automatically, without conscious effort
    • What are the two main divisions of the autonomic nervous system?
      Sympathetic and parasympathetic
    • How many neurons connect the CNS to effectors in the autonomic nervous system?
      Two neurons
    • What are the names of the two neurons in the autonomic nervous system pathway?
      Preganglionic and postganglionic neurons
    • Where does the synapse between the preganglionic and postganglionic neurons occur?
      In an autonomic ganglion
    • What is the role of the preganglionic axon in the autonomic nervous system?
      Forms a synapse with postganglionic neuron
    • What are the three kinds of autonomic ganglia?
      Sympathetic ganglia, prevertebral ganglia, terminal ganglia
    • Where are sympathetic ganglia located?
      Close to the spinal cord
    • What is another name for the sympathetic system?
      Thoracolumbar division
    • Where do the cell bodies of preganglionic neurons in the sympathetic division occur?
      In the lateral horns of gray matter
    • Where are terminal or intramural ganglia located?
      Near or within target organs
    • What is another name for the parasympathetic system?
      Craniosacral division
    • What cranial nerves are associated with the parasympathetic division?
      III, VII, IX, and X
    • What does the sympathetic division prepare the body for?
      Stressful or emergency situations
    • What physiological changes occur during sympathetic activation?
      Increased heart rate and dilated airways
    • What does the parasympathetic division control?
      Body processes during ordinary situations
    • How does the parasympathetic division affect heart rate and blood pressure?
      Slows heart rate and decreases blood pressure
    • What is the primary function of the parasympathetic division?
      Conserves and restores energy
    • What does the parasympathetic division stimulate in the digestive system?
      Processes food and eliminates wastes
    • What additional effects does the sympathetic division have on the body during stress?
      Causes sweating and pupil dilation
    • How does the parasympathetic division contribute to tissue health?
      Restores and builds tissues
    • What is the significance of energy release during sympathetic activation?
      Increases muscular strength for emergencies
