Levator Glandulae Thyroideae
increases metabolic activity of most cell in body
(Thyroid Gland)
Hormones Thyroxine and Triiodothyronine
produced by parafollicular cells that lower the level of blood calcium
(Thyroid Gland)
Thyrocalcitonin
small ovoid, lie external to the fibrous thyroid capsule
Parathyroid Gland
lie middle of the posterior border of the thyroid gland
Superior parathyroid glands
close to the inferior pole of thyroid gland
inferior parathyroid glands
stimulates osteoclastic activity in bone causing mobilization of bone calcium and increase calcium level in blood
(Parathyroid)
Parathyroid Hormone
