Study Notes
Thyroid Gland Function
- The thyroid gland regulates growth, development, and metabolic rate.
Thyroid Hormone Regulation
- The hypothalamus and pituitary gland control the secretion of T3 and T4 hormones through a negative feedback mechanism.
Calcitonin Production
- The C cells of the thyroid stroma produce Calcitonin, a hormone that regulates calcium levels in the blood.
Thyroid Gland Structure
- The thyroid gland consists of 2 lateral lobes connected by an isthmus.
Thyroid Hormone Storage
- T3 and T4 hormones are stored in the thyroid gland in the form of thyroglobulin, a protein-bound complex.
