Bone mineral density | Measurement that is taken to determine the degree of bone loss |
Catecholamines | Hormones made in the brainstem, nervous system and adrenal glands |
Calcitonin | Thyroid hormone that helps regulate blood concentrations of calcium abd phosphate |
Cretinism | Condition in which the development of the brain and body is inhibited by congenital lack of thyroid secretion |
Cushing's disease | Syndrome caused by excessive production of adrenocorticotropic hormone |
