Endocrine gland hormones at target cells "Permissiveness" is the situation in which a hormone cannot exert its full effects without the presence of another hormone. "Synergism" occurs when two or more hormones produce the same effects in a target cell and their results are amplified. "Antagonism" occurs when a hormone opposes or reverses the effect of another hormone. The endocrine glands belong to the body's control system. The hormones which they produce help to regulate the functions of cells and tissues throughout the body. Endocrine organs are activated to release their hormones by humoral, neural or hormonal stimuli. Negative feedback is important
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
