Document Summary

Hormones exert their effects on target tissue. The specificity of hormone target cell interaction is determined by receptors in a lock-and-key type of mechanism. The regulation of hormone levels in the blood depends on a highly specialized mechanism called feedback. With negative feedback, the gland responds by increasing or decreasing the secretion of a hormone based on feedback from various factors. The hypothalamus and pituitary gland integrate communication between the nervous and endocrine systems. Growth hormone (gh) has effects on all body tissues. Antidiuretic hormone (adh) regulates fluid volume by stimulating reabsorption of water in the kidneys. Oxytocin stimulates ejection of milk into mammary ducts and contraction of uterine smooth muscle. Calcitonin is a hormone produced by c cells (parafollicular cells) of the thyroid gland in response to high circulating calcium levels. The parathyroid glands are four small, oval structures usually arranged in pairs behind each thyroid lobe. They secrete parathyroid hormone (pth), which regulates the blood level of calcium.
