Study Notes
- Metabolic rate regulation involves body temperature and exposure to cold in adults.
- Thyroid hormone production increases when exposed to cold.
- Thyroxin release is stimulated by thyroid-stimulating hormone (TSH) from the anterior pituitary.
- Thyroid-releasing hormone (TRH) from the hypothalamus stimulates the anterior pituitary to release TSH.
Hyperthyroidism
- Hyperthyroidism is caused by excessive thyroid hormone secretion.
- Symptoms include profuse sweating, weight loss, heat intolerance, irritability, and high blood pressure.
Hypothyroidism
- Hypothyroidism is caused by low thyroid hormone secretion.
- Symptoms include weight gain, lethargy, and cold intolerance in adults.
- Children born with hypothyroidism experience stunted growth and intellectual disability, known as cretinism.
- Goiter, an enlargement of the thyroid, results from a thyroid hormone shortage, often due to iodine deficiency.
Calcitonin
- Calcitonin is a peptide hormone that maintains proper calcium (Ca++) levels in the blood.
- When blood calcium concentration is too high, calcitonin stimulates calcium uptake into bones to lower its concentration in the blood.
