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
This quiz reviews the regulation of hormone secretion, particularly in the thyroid gland, and the roles of TRH, TSH, and Calcitonin.
