General Principles Contrast the terms endocrine, paracrine, and autocrine Detine the terms hormone, target cell, and receptor. Compare and contrast hormone actions exerted via plasma membrane receptors with those mediated via intracellular receptors Understand the role of hormone-binding proteins Understand the feedback control mechanisms of hormone secretion Explain the effects of secretion, degradation, and excretion on plasma hormone concentrations Understand the basis of hormone measurements and their interpretation
