Question Answer
what gland in known as the butterfly glandthyroid gland
what 2 hormone does the thyroid produceparafollicular cells and follicular cells
what does the parafollicular cell producecalcitonin
what does the follicular cell producethyroid hormone T3- T4
what are the functions of T3 and T4 hormonesuse of glucose and fatty acids, temperature, increase BMR
