    Study Notes

    Hormone Regulation

    • GnRH (Gonadotropin-Releasing Hormone) regulates hormone secretion in the uterus
    • TRH (Thyrotropin-Releasing Hormone) stimulates the release of TSH (Thyroid-Stimulating Hormone) from the anterior pituitary gland

    Thyroid Hormones

    • Calcitonin is the most abundant hormone in the thyroid gland
    • T3 (Triiodothyronine) and T4 (Thyroxine) are produced by the thyroid gland
    • T3 is used before thyroid surgery
    • T4 cannot be used for weight loss and must be checked for thyroid levels

    Thyroid Disorders

    • Hyperthyroidism can be caused by cancer
    • Treatments for hyperthyroidism include propylthiouracil, methimazole, or surgery
    • BID (twice a day) and QD (once a day) are medication schedules for thyroid treatment

    Pregnancy and Thyroid

    • Thyroid storm can occur during pregnancy, causing weight gain, chills, and fever

    Bone Health

    • Phosphate is essential for bone health
    • VitD is essential for Phos absorption, and diet plays a crucial role
    • Ent (enteral nutrition) and Cart (cartilage health) are related to bone health

    Anterior Pituitary

    • The anterior pituitary gland regulates hormone secretion, including TSH
    • Labor and vasoconstriction are related to anterior pituitary function
