hormones are secreted by what
glands and cirluate the body
3 of 92
hormones target what
specific organs and tissues in the body
4 of 92

organs for secondary endocroine functions
5 of 92

at the base of the brain in the bony cavity. the anterior and posterior
6 of 92
what is the function of the pituitary gland in the endocrine system

7 of 92

8 of 92
the anterior pituitary gland coordinates signals from where
the hypothalamus and endocrine organs
9 of 92
what does the anterior pititary gland secrete

28 of 92
treatment for hyperthyroidism
medication such as thionamides e.g. carbinmazole. Radioactive iodine, destroys the thyroid cells limiting the amount of thyroid hormone produced. Surgery to remove part or all of the gland. Removal of all would lead to meds required for life

36 of 92
what are the parathyroid glands
4 peasized glands beind the thyroid gland in the neck which produces parathyroid hormones
37 of 92
function of the parathyroidn gland
control the levels of calcium in the blood for bone strength and function of nervous system and muscle
38 of 92
If the ca levels are low in the blood what happens
the parathyroid hormone is secreted, causing the bones to release ca into the blood and the kidneys stop losing ca in the urie and stimulates the increase of vit d metabolism

42 of 92
treatment for primary hyperparathyroidism
monitor ca levels in blood. or a parathyroidectomy, the number of glands removed will be determined by the blood test
