Endocrine System & Metabolism : Gland & Hormone Flashcards
Anterior Lobe of Pituitary
GH (growth hormone)
TT: most tissues in the body
PA: stimulates growth by promoting protein synthesis
Hypothalamus
Releasing & inhibiting hormones
TT: anterior lobe of pituitary glad
PA: stimulates / inhibits secretion of specific hormones
Anterior Lobe of Pituitary
TSH (thyroid-stimulating hormone)
TT: thyroid gland
PA: increases secretion of thyroid hormone: increases the size of the thyroid gland
Anterior Lobe of Pituitary
ACTH (adrenocorticotropic hormone)
TT: adrenal cortex
PA: increases secretion of adrenocortical hormones, especially glucocorticoids such as cortisol
Anterior Lobe of Pituitary
FSH (follicle-stimulating hormone)
TT: ovarian follicles in females; seminiferous tubules of testes in men
PA: follicle menstruation & estrogen secretion in females; spermatogenesis in men
Anterior Lobe of Pituitary
LH (luteinizing hormone)
ICSH (interstitial cell-stimulating hormone in men)
TT: ovary in women; testis in men
PA: ovulation; progesterone production in women; testosterone production in men
Anterior Lobe of Pituitary
Prolactin
TT: mammary gland
PA: stimulates milk production
Posterior Lobe of Pituitary
ADH (antidiuretic hormone)
TT: kidneys
PA: increases water reabsorption (decreases water lost in urine)
Posterior Lobe of Pituitary
Oxytocin
TT: uterus: mammary gland
PA: increases uterine contractions; stimulates ejection of milk from mammary gland
Thyroid Gland
Thyroxine (T4) & Triiodothyronine (T3)
TT: most body cells
PA: increases metabolic rate: essential for normal growth & development
Thyroid Gland
Calcitonin
TT: primarily bone
PA: decreases blood calcium by inhibiting bone breakdown & release of calcium; antagonistic to parathyroid hormone
Parathyroid Gland
PTH (parathyroid hormone / parathormone)
TT: bone, kidneys, digestive tract
PA: increases blood calcium by stimulating bone breakdown & release of calcium; increases calcium absorption in the digestive tract; decreases calcium lost in urine
Adrenal Cortex
Aldosterone (mineralocorticoids)
TT: kidneys
PA: increases sodium reabsorption & potassium excretion in kidney tubules; secondarily increases water retention
Adrenal Cortex
Cortisol (glucocorticoids)
TT: most body tissues
PA: increases blood glucose levels, inhibits inflammation & immune response
Adrenal Cortex
Androgens & Estrogens
TT: most body tissues
PA: secreted in small amounts to that effect is generally masked by the hormones from the ovaries & testes
