Hyper & Hypopituitarism Introduction Hyperpituitarism is the result of excess secretion of adenohypophyseal trophic hormones. Hypopituitarism is the decreased secretion of one or more of the pituitary hormones. If there is decreased secretion of most pituitary hormones‚ this condition is called panhypopituitarism (pan meaning "all"). Historical Background The pituitary was known by Galen‚ and various theories were proposed about its role in the body. In the late 19th century‚ acromegaly

release the hormones into the blood stream and are transported to the various cells and body parts. When the hormones reach the target site‚ they bind to the receptor cells with a lock and key mechanism. The hormone may be present within the nucleus or on the surface of the cells. Once bound to the receptor‚ the hormones transmit a signal that triggers an action by the site. Hormones control the organ’s function and affect the growth and development of the organs. It is due to the hormones that the

The Pituitary Gland and Dwarfism The Pituitary Gland is situated at the base of the brain and it produces hormones which control growth. Too large an amount of these hormones causes giantism‚ a condition where facial features‚ hands‚ etc. become abnormally large. Too little causes dwarfism‚ where the overall stature of a person is very small. Dwarfism is the condition of being undersized‚ or less than 127 cm (50 in) in height. Some dwarfs have been less than 64 cm (24 in) in height when fully

The endocrine system is a control system of ductless glands that secrete chemical "instant messengers" called hormones that circulate within the body via the bloodstream to affect distant cells within specific organs. Endocrine glands secrete their products immediately into the blood or interstitial fluid‚ without storage of the chemical. Hormones act as "messengers‚" and are carried by the bloodstream to different cells in the body‚ which interpret these messages and act on them. Typical endocrine
