功能

Produces thyroid hormones (T3 and T4) that regulate metabolic rate, protein synthesis, and sensitivity to other hormones. Also produces calcitonin, which helps regulate calcium homeostasis.

临床意义

Hypothyroidism (Hashimoto's thyroiditis) and hyperthyroidism (Graves' disease) are common endocrine disorders. Thyroid nodules and goiter affect millions. Thyroid cancer, while relatively uncommon, has excellent prognosis when treated early. Thyroidectomy risks recurrent laryngeal nerve injury.
