Endocrine Review
| Question | Answer |
|---|---|
| Describe hypothalmus | -influences thyroid gland along with the pituitary -serves as link between endocrine and nervous systems |
| Describe pineal gland | -shaped like pine-cone -attached to posterior part of third ventricle of brain -secretes hormone melatonin |
| Describe pituitary | -aka hypophysis -pea-sized organ located at base of brain -master gland -regulates many body activities -stimulates other glands to secrete their own specific hormones |
| 2 hormones by posterior pituitary and their target | ADH-vassopressin,targets kidneys Oxytocin, targets uterus and breasts |
| Describe thyroid gland | -largest gland -H shaped organ -composed of 2 large lobes separated by isthmus |
| 6 hormones by anterior and their target | -ACTH, targets adrenal cortex -FSH, targets ovaries, testes -GH, targets bones, cartilage, liver, muscle, and other tissues -LH, ovaries, testes -PRL, breasts -TSH, thyroid gland |
| function of endocrine glands | secrete hormones directly into the blood stream |
| three types of steroid hormones secreted by the adrenal cortex | -mineralocorticoids (kidneys) -glucocorticoids (body cells) -sex hormones (female libido) |
| two hormones secreted by the adrenal medulla and their function | -epinephrine and norepinephrine function- sympathetic nervous system (SNS) |
| function of the parathyroid glands | increase blood calcium levels |
| where are the adrenal glands located | superior surface of the kidneys |
| three disorders associated with the thyroid gland | -cretinism -myxedema -Graves disease |
