Endocrine system "krīnō", "to separate, distinguish". The human endocrine system consists of several systems that operate via feedback loops. Several important feedback systems are mediated via the hypothalamus and pituitary. Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into interstitial spaces and then absorbed into blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The hypothalamus and pituitary gland are neuroendocrine organs. There are many types of cells that comprise the endocrine system and these
Endocrine bone disease Endocrine bone disease An endocrine bone disease is a bone disease associated with a disorder of the endocrine system. An example is osteitis fibrosa cystica. The thyroid, parathyroid, pituitary, or adrenal glands, and the pancreas are parts of the endocrine system, and, therefore are associated with the endocrine bone disease. Some common endocrine disorders are hypothyroidism, hyperthyroidism, Paget’s disease, Osteoporosis, and diabetes. The thyroid gland produces thyroxin (T3, and T4) which is necessary for normal development of the nervous system. Its functions include: promoting growth, increasing basal metabolic rate and controlling body temperature. Adequate iodine intake is necessary for the
