hormones secreted by the thyroid T4, T3, and calcitonin T4 and T3 increases metabolism in the body cells calcitonin lowers blood calcium hyperthyroidism (graves disease) fast heart rate, exophthalmos, weight loss, hyperactivity hypothyroidism in adults myxedema (slower heart rate, wt gain, fatigue) hypothyroidism in children and infants cretinism (slower heart rate, wt gain, fatigue) hormones secreted by the parathyroids parathyroids parathyroids increases blood calcium hormones secreted by the adrenal cortex cortisol, aldosterone, sex hormones hormones secreted by the adrenal medulla epinephrine, norepinephrine hormones secreted by the pancreas islet cell glucagon, insulin hormones secreted by the pituitary anterior lobe growth hormone, thyroid stimulating hormone, ACTH, follicle stimulating hormone, luteinizing hormone, prolactin hormones secreted by the pituitary posterior lobe antidiurtetic hormone, oxytocin hormones secreted by the ovaries estrogen, progesterone hormones secreted by the testes testosterone cortisol increases blood sugar aldosterone increases reabsorbtion of Na sex hormones secondary sex characteristics epinephrine and norepinephrine sympathomimetic insulin decreases blood sugar glucagon increases blood sugar growth hormone increases bone and tissue growth TSH stimulates the thyroid gland ACTH stimulates the adrenal cortex especially cortisol follicle stimulating hormone oogenesis and speratogenesis luteinizing hormone pormotes ovulation and testosterone secretion prolactin promotes growth of breast tissue and milk antidiuretic hormone stimulates reabsorbtion of H2O by kidneys oxytocin stimulates contraction of the uterus estrogens development of ova and secondary sex characteristics progesterones prepares and maintains the uterus during pregnancy testosterone sevelopment of the sperm and secondary sex characteristics cushing syndrome adrenal cortex hypersecretion excessive hair growth, buffalo hump, moon face addison disease hyposecretion of the adrenal cortex Diabetes Mellitus Type I juvenile onset little or no insulin production Diabetes Mellitus Type II adult onset, decreased insulin production acromegaly hypersecretion of the anterior lobe of the pituitary gland in adulthood causes increased growth of the hands, feet and face gigantism hypersecretion of the anterior lobe of the pituitary gland causeslong bones to grow during childhood dwarfism hyposecretion of the anterior lobe of the pituitary gland smaller in stature diabetes insipidus hyposecretion of the posterior lobe of the pituitary lobe causes polyuria and polydipsia
