  • Hormone-Receptor Binding

  • Positive and Negative Feedback System

  • Negative FeedbackGland X releases hormone X this stimulates target cells to release hormone YWhen there is an excess of hormone Y gland X senses this and inhibits it release of hormone X

  • Hypothalamus

  • Endocrine Glands: Adrenal GlandsAdrenal cortexmineralocorticoids (aldosterone), corticosteroids (cortisol)Adrenal medullacatecholamines (norepinephrine and epinephrine)

  • Thyroid Gland Control of metabolismCalcium and phosphorus balance

  • Parathyroid GlandParathyroid hormone (PTH)CalciumPhosphorous

  • Pancreas

  • Assessment MethodsPatient history

    Nutrition history

    Family history

    Genetic risk

    Current health problems

  • Assessment Methods Current health problems including any changes in:Energy levelsEliminationSexual and reproductive functionsPhysical appearance

  • Physical AssessmentExamine for:Prominent forehead or jawRound or puffy faceDull or flat expressionExophthalmosVitiligoAbdominal StriaeHirsutism

  • PalpationOnly gland that can be palpated

  • Laboratory TestsStimulation/suppression tests

    AssaysAllows for many different hormones to be analyzed at the same time

    Urine tests24 hour

    Tests for glucoseHbA1C

    Imaging assessment

    Other diagnostic assessmentNeedle biopsy
