    T3/T4 needs iodine to synthesize.
    T3: strong; speeds up metabolism.

    T4: weak; maintains steady metabolism.

    calcitonIN: decrease serum Ca++ levels by pulling Ca++ and depositing it into bone.
  2. Labs & Diagnostics.

    What does the Pituitary gland secrete when thyroid hormone is low?
    • TSH: (in pituitary) stimulates the secretion of thyroid hormone.
    • Serum T3/T4

    • Thyroid Scan
    • Biopsy
    • *RAI (radioactive Iodine Uptake): how good the thyroid is taking up the iodine.
