1-26 Flashcards
___ Releasing Hormone
Hypothalamus
Tells Ant. Pituitary to increase effect of a hormone
___Inhibiting Hormone
Hypothalamus
Tells Ant. Pituitary to decrease effect of a hormone
Human Growth Hormone (hGH)
Ant. Pituitary
Stimulates cell growth, Releases glucose into blood
Thyroid-stimulating Hormone (TSH)
Ant. Pituitary
Tells thyroid gland to release T4 and T3
Follicle-stimulating Hormone (FSH)
Ant. Pituitary Stimulates Gonads (Ovary, Testis) to make Gametes
Lutenizing Hormone (LH)
Ant. Pituitary
Causes ovulation, Tells Gonads to release Sex Hormones
Prolactin (PRL)
Ant. Pituitary
Tells Mammary Glands to make milk
Adrenocorticotropic Hormone (ACTH)
Ant. Pituitary
Tells Adrenal Gland to secrete glucocorticords (Cortisol)
Melanocyte-stimulating Hormone (MSH)
Ant. Pituitary
Role in brain activity, probably learning and memory
Oxytocin (OT)
Post. Pituitary
Stimulates contractions of uterus, release of milk
Antidiuretic Hormone (ADH)
Post. Pituitary
Body to retain NA+ and then by water, decreases urine
Triiodothyronine (T3)
Thyroid Gland
Increase metabolic rate, most potent
Thyroxine (T4)
Thyroid Gland
Increase metabolic rate, most made, Body converts to T3
Calcitonin (CT)
Thyroid Gland
Lowers serum levels of Calcium (Ca++)
Parathyroid Hormone (PTH)
Parathyroid gland
Raises serum levels of Calcium (Ca++)
Aldosterone (mineralocorticord)
Adrenal cortex zona glomerulosa
Increase Na+ retention (retain water)
Cortisol (glucocorticord)
Adrenal cortex zona fasciculate
Role stress, inflammation, immunity, raises serum glucose
dihydroepiandrosterone (androgens) (DHEA)
Adrenal cortex zona reticularis
Role axillary & pubic hair growth, libido (esp. in females)
Epinephrine (Epi)
Adrenal medulla
Role in sympathetic responses
Norepinephrine (Nor)
Adrenal medulla
Role in sympathetic responses
Glucagon
Panceas (alpha)
Raises serum glucose (Fasting hormone)
Insulin
Pancreas (beta)
Lowers serum glucose (digesting hormone)
Melatonin
Pineal Gland
Role in sleep cycle, increased in sleep, decreased awake
Estrogen
Ovary
Stimulates female 2’ sex characteristics
Role menstrual cycle and pregnancy
Progesterone
Ovary
Role menstrual cycle and pregnancy
Testosterone
Testis
Stimulates male 2’ sex-characteristics, gamete production
