    13. Explain the role of cholinergic and adrenergic fibers.
    14. Explain how “fight-or-flight” reaction and the salivation-lacrimation-urination- defecation (SLUD) reactions are dependent on ANS structure and physiology.
  2. Analyze the components, organization and physiological processes of the endocrine system.
    1. List the chemical classes of hormones, and give examples of each type.
    2. Compare mechanisms of target tissue stimulation.
      1. Lipid - soluble hormones
      2. Water - soluble hormones
    3. Explain the role of the hypothalamus and adenohypophysis in regulation of hormone release.
    4. Define a tropic hormone, and use an example to illustrate its mechanism of action.
    5. List the hormone(s) released from each of these glands, and describe their actions:
      1. Adenohypophysis
      2. Pineal
      3. Thymus
      4. Thyroid
