Adh targets which organ

By nerve cells neurones. By the bloodstream. Muscles or glands. Target cells in particular tissues. Muscle contraction or secretion. Chemical change. Very rapid. Short until nerve impulses stop. Clearly, robust control systems must be in place to prevent over or under-secretion of hypothalamic and anterior pituitary hormones.

A prominent mechanism for control of the releasing and inhibiting hormones is negative feedback. Details on the control of specific hypothalamic and anterior pituitary hormones is presented in the discussions of those hormones. The following table summarizes the major hormones synthesized and secreted by the pituitary gland, along with summary statements about their major target organs and physiologic effects.

Keep in mind that summaries are just that, and ongoing research continues to delineate additional, sometimes very important effects. A final point to be made is that individual cells within the anterior pituitary secrete a single hormone or possibly two in some cases. Endocrine Gland Hormone Exercise effect Target organ Major function Hypothalamus Releasing hormones Increases with anticipation of exercise Pituitary gland Stimulates the pituitary gland to release hormones Inhibiting hormones Increases with cessation of exercise Pituitary gland Inhibits release of pituitary gland hormones.

Nor adrenaline Nor epinephrine Increases with increasing exercise intensity or duration Acts on most cells in the body prolonging and intensifying the sympathetic nervous system response to stress Mobilises glucose, increases heart rate, heart contractility, oxygen use and blood flow to skeletal muscles Constricts blood vessels and elevates blood pressure.

Cortisol Increases with heavy exercise Most cells in the body Increases blood sugar levels, aids the metabolism of fats, CHO and proteins, suppresses the immune system, has an anti-inflammatory action. Endocrine Gland Hormone Exercise effect Target organ Major function Pancreas Insulin Decreases with increasing exercise All cells in the body Controls blood glucose by lowering blood glucose levels Glucagon Increases with increasing exercise All cells in the body Increases blood glucose, stimulates breakdown of glycogen and fat Kidneys Renin Increases as blood pressure lowers Adrenal Cortex Assists in blood pressure control Gonads: Testes Testosterone Increases with increasing exercise Sex organs Development of male sex organs, facial hair and change in voice Muscle Promotes muscle growth Ovaries Oestrogen Sex organs Development of female sex organs, regulates menstrual cycle Adipose tissue Storage of fat.

Like the nervous system, hormones can control the body. The effects are much slower than the nervous system, but they last for longer. There are important differences between nervous and hormonal control. The glands in the body produce a range of different chemical hormones that travel in the bloodstream and affect a number of different organs in the body.

The diagram below shows this in detail. Important hormones released into the bloodstream include ADH anti-diuretic hormone , adrenaline and insulin. The pituitary gland in the brain is known as a 'master gland'. It secretes several hormones into the blood in response to the body's condition, such as blood water levels.
