    1. AA) Works rapidly across very short distances
    2. BB) Structurally related to each other and their target organs
    3. CC.) Duration of action is very brief
    4. DD.) Chemical messenger is carried over long distances in the blood
    5. EE.) Coordinates very precise responses
  2. 2Hydrophilic hormone binding to a receptor with multiple transmembrane domains and which activates, via an effector protein, a second messenger system within the target cell is characteristic of a:
    1. AA.) G-protein coupled receptor
    2. BB.) Tyrosine kinase receptor
    3. CC.) Chemically gated receptor channel
    4. DD.) depolarization
    5. Ee.) Hormone response element
  3. 3Which of the following describes a lipophilic hormone?
    1. AA.) Secreted as it is synthesized
    2. BB.) Does not use transport proteins in the blood
    3. CC.) Acts solely through receptors located at the cell membrane
    4. DD.) Acts predominantly through second messenger systems
    5. EE.) Initially synthesized as a preprohormone
  4. 4Which of the following would contribute to a rise in plasma hormone concentration?
    1. AA.) Increased amounts of binding proteins
    2. BB.) Increased secretion rate
    3. CC.) Reduced activation/conversion of the inactive hormone
    4. DD.) Increased metabolism/clearance
    5. EE.) Reduced secretion of the hormone
  5. 5The situation where the output of a system opposes the input is:
    1. AA.) Antagonism
    2. BB.) Permissiveness
    3. CC.) Synergism
    4. DD.) Negative feedback
    5. EE.) Positive feedback
  6. 6Which of the following is NOT true about a circadian rhythm?
    1. AA.) Driven by the suprachiasmatic nucleus
    2. BB.) Occurs with a periodicity of every hour
    3. CC.) Involves self-starting clock proteins
    4. DD.) Can be synchronized by the environment
    5. EE.) Periodicity is influenced by melatonin
  7. 7The posterior pituitary:
    1. AA.) Is functionally, but not anatomically connected to the hypothalamus
    2. BB.) Secretes tropic hormones in response to releasing hormones
    3. CC.) Derived from Rathke’s pouch
    4. DD.) Secretes hormones originally produced in neurons of the paraventricular nucleus
    5. EE.) Is a major source of growth hormone
  8. 8Which of the following is NOT true about vasopressin?
    1. AA.) Decreased osmolarity is the biggest stimulus for its release
    2. BB.) Released in response to a large decrease in atrial volume
    3. CC.) Inserts aquaporins into kidney collecting tubules to increase water retention
    4. DD.) Has a pressor effect via arteriolar smooth muscle
    5. EE.) Release triggered by exertion in a hot environment
