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 covers the regulation of hormone secretion in the uterus and thyroid gland, including the roles of GnRH, TRH, TSH, calcitonin, T3, and T4.
