|
Pituitary Gland
|
Controls activity of many other endocrine glands
|
|
|
Adrenals
|
maintains salt levels in the blood, maintains BP, controls kidney function and helps control fluid concentration in the body
|
|
|
Pancreatic islet cells
|
helps maintain glucose metabolisim
|
|
|
Thyroid
|
controls metabolisim
|
|
|
Parathyroid
|
controls calcium levels in the body
|
|
|
Stimulation Test
|
stimulus provided to see if the gland is capable of normal production, failure of level to rise = hyposecretion
|
|
|
Supression Test
|
used when levels are high, failure to supress production indicates hypersecretion
|
|
|
Assays
|
levels of hormones in blood or body fluids
|
|
|
Anterior Pituitary: Growth hormone
|
Hypo=dwarfisim
Hyper= gigantisim and acromegaly |
|
|
Posterior Pituitary: Vasopressin(ADH)
|
hypo=diabetes insipidus
hyper= SIADH |
|
|
Adrenal Gland: Cortex
|
Hypo= Addisons and Adrenal Crisis
Hyper= Cushings |
|
|
Adrenal Gland: Medulla
|
Hyper= Pheochromocytoma
|
|
|
Parathyroid (PTH)
|
Hypo= tetany, arrythmias and muscle spams
Hyper= renal stones and signs of heart block |
|
|
Thyroid (t3 & t4)
|
Hypo= Cretinism, Myxedma and Goiter
Hyper= Graves Disease and Thyroidtoxosis/Thyroid storm |
|
|
Pancreas: Insulin
|
Hypo= Diabetes Mellitus and Diabetic Ketoacidosis
Hyper= hypoglycemia and Insulin Shock |
|
|
Tropic Hormones
|
hormones whose secretions stimulate tissue or glands
|
|
|
Target Glands
|
Tissue that is affected by the hormones
|
|
|
Pituitary Gland Hormones
|
Posterior--> GH, TSH, ACTH, LH, FSH, PRL and MSH
Anterior--> Vasopressin(ADH) and Oxytocin |
|
|
Adrenal Gland Hormones
|
Cortex--> Mineral Corticoids(Aldosterone), Glucocorticoids(corticostroids, cortisone and cortisol) and Gonadicorticoids(androgens)
Medulla: Epinephrine and Norepinephrine |
|
|
Thyroid Gland Hormones
|
t4 thyroxin, t3 ttriodonthyroine and thyrocalcitonin
|
|
|
Parathyroid Hormones
|
PTH
|
|
|
Pancrease Hormones
|
Glucagon (alpha cells), Insulin (beta cells) and Somatostatin (delta cells)
|
|
|
Hypopituitarisim
|
Deficiency of pituitary hormones,focus on replacement of hormones
|
|
|
Gonadotropin Replacement
|
give testosterone to males and progesterone and estrogen to females
|
|
|
Growth Hormone Replacement
|
Give GH subQ
|
|
|
TSH replacement
|
Replace with thyroid hormone and glucocorticoids (cortisol)
|
|
|
ACTH replacement
|
Replace with hydrocortisone, cortisone, prednisolone and prednisone
|
|
|
Hyperpituitarisim
|
Hpersecretion of GH --> Acromegaly and gigantisim and cushings and sexual dysfunctions
|
|
|
Pharmacologic treatment for hyperpituitarisim
|
Stimulate dopamine receptors and inhibit PRL and GH. Parlodel and Dostinex
Somatostatin Analog: Sandostatin |
|
|
Surgery for hyperpituitarisim
|
Hypophysectomy--> removal of the pituitary gland and/or tumor.
|
|
|
Hyposecretion Posterior Pituitary: Diabetes Insipidus treatment
|
Diabinese: increases action of exsisting ADH(monitor for hypoglycemia)
Vasopressin replacement |
|
|
Hypersecretion Anterior Pituitary: SIADH
|
Excessive ADH
Drugs that cause it= tricycle antidepressants, opiods and chlorpropamide |
|
|
Hypersecretion Anterior Pituitary: SIADH Treatment
|
NaCl replacement, diuretics, lithium and declomycin
|
