Explanation / Answer

a) ADH: The negative feedback mechanism of ADH is by the atrial natriuretic factor. It is produced when the concentration of water in the blood is high.This hormone inhibits the release of ADH which causes the kidney to produce dilute urine. 3 receptors-AVPR1A, AVPR1B,AVPR2 Storage and release -posterior pituitary but controlled by hypothalamus -------------------------------------------------------------------------------- b) ACTH: The negative feedback mechanism is by glucocorticoids. These hormones act negatively on the hypothalamus which directs the pituitary gland to stop its production of ACTH. Receptors are present on adrenocortical cells of adrenal cortex Released by the anterior pituitary but controlled by the hypothalamus -------------------------------------------------------------------------------- c)Calcitonin: It is produced by the thyroid gland.. Receptors are present on osteoclasts Feedback mechanism is the low levels of calcium in the blood. -------------------------------------------------------------------------------- d) Oxytocin: REceptors are G protein coupled receptors It is released by the posterior pituitary but controlled by hypothalamus Positive feedback by suckling of the child stimulates the posterior pituitary to produce more amount of hormone. -------------------------------------------------------------------------------- e) Cortisol: Hypothalamus is the control Negative feedback is by cortisol on the hypothalamus and the pituitary -------------------------------------------------------------------------------- f) Aldosterone: Intracellular receptors The negative feedback mechanism of Aldosterone is by the atrial natriuretic factor. It is produced when the concentration of sodium in the blood is high.This hormone inhibits the release of aldosterone which causes the kidney to excrete sodium ions. -------------------------------------------------------------------------------- g)Adrenalin: Hypothalamus is control This is released during periods of stress
