on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability changes or production of a substance inside the cell. Other hormones diffuse into the cell and cause new proteins to be produced. The secretion of hormones is controlled by negative-feedback mechanisms. The major endocrine glands

Osmoregulation is the active regulation of the osmotic pressure of an organism’s fluids to maintain the homeostasis of the organism’s water content; that is‚ it keeps the organism’s fluids from becoming too diluted or too concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis. The higher the osmotic pressure of a solution‚ the more water tends to move into it. Pressure must be exerted on the hypertonic side of a selectively permeable

consequences of denying that opportunity. Love is as important to the individual as it is to their society and our world. At the time of birth‚ and for about an hour following birthing‚ the mother and her newborn baby are swamped in a cocktail of hormones.

of the antidiuretic hormone. Diabetes insipidus doesn’t produce enough ADH or respond to it‚ thus produces too much urine. SIADH is the opposite and retains too much water‚ rather than excreting it excessively in DI. 8. Polyuria-sickle cell diseases‚ pyelonephritis.

their feeding young. Lactation occurs with the help of two hormones‚ prolactin (PRL) and oxytocin. While PRL and oxytocin act independently on different nerve receptors‚ their combined actions are essential for successful lactation; prolactin for the production of milk and Oxytocin to open the milk ducts. Oxytocin‚ the bonding hormone‚ permits the mother to bond with her child when still in her wound and when breastfeeding. This special hormone also helps to contract the uterus and expel the placenta

Neurogenic DI- is caused by a deficiency of antidiuretic hormone Nephrogenic DI- is caused by insensitivity of the kidneys to effect the antidiuretic hormone Dispogenic DI- is caused by being really thirty and drinking way too much liquid of any kind. Gestagenic DI- is only during pregnancy and it is causd by a deficiency of the antidiuretic 4. How is pituitary diabetes insipidus diagnosed? It is diagnosed with a urinalysis‚ a
