Hormones: Sources, Targets and FunctionsSource Hormone Target Physiologic Effect
Anterior pituitary
Follicle-stimulatinghormone (FSH)
Ovary and Testes
Growth ofovarian follicles orseminiferous tubules
Anterior pituitary
Luteinizing hormone(LH)
Ovary and Testes
Production ofestrogen and progesteroneor testosterone
Anterior pituitary
Prolactin (LTH)Ovary and Mammary
Stimulate milk production in breastmaintain secretion of estrogen and progesterone by ovary
Anterior pituitary
Thyroid stimulatinghormone (TSH)
ThyroidStimulates secretion of thyroid hormones
Anterior pituitary
Adrenocorticotropichormone (ACTH)
Adrenal cortexStimulates secretion of adrenal cortex hormones
Anterior pituitary
Growth hormone (GH) General Stimulates growth
Anterior pituitary
Melanocyte-stimulatinghormone (MSH)
MelanocytesStimulates dispersal of pigment in chromatophores
Hypothalamus viaposterior pituitary
OxytocinUterus and Mammary
Stimulates contraction andsecretion of milk
Hypothalamus viaposterior pituitary
Antidiuretic hormone (ADH)
KidneyStimulates reabsorption of water
Thyroid glandThyroxin andtriodothyroxin
GeneralStimulates metabolism, growth and development
Thyroid gland Calcitonin BoneLowers blood calcium level byinhibiting bone breakdown
Parathyroid gland
Parathyroid hormoneBone, kidneydigestive tract
Increases blood calcium bystimulating bone breakdown
Adrenal cortexMineralocorticoids(aldosterone)
KidneyMaintain sodium and phosphate balance
Adrenal cortexGlucoocorticoids(cortisol)
GeneralRaise blood-glucose leveladapt to long-term stress
Adrenal cortexDehydroepiandrosterone(DHEA)
Stimulate sex driveinduce labor
Adrenal medulla
Epinephrine(adrenalin)
Muscle, liverStimulates glucose releaseshort term cope with stress
Adrenal medulla
Norepinephrine Blood vesselsConstricts blood vesselsincrease heart rate
Pineal gland MelatoninGonads, pigment cellsother cells
Control biorhythmsinfluence reproduction
Pancreasalpha cells
GlucagonLiverfatty tissue
Raise blood glucose concentrationstimulate gluconeogenesis
Pancreasbeta cells
Insulin GeneralLower blood glucose concentrationstimulate glycogen synthesis
OvaryEstrogenestradiol
Generaluterus
Develop/maintain female characteristicsstimulate growth of uterine lining
Ovary ProgestrogenUterusbreast
Stimulate development of uterine lining
Ovary andplacenta
RelaxinPelvic ligaments
Relaxes pelvic ligaments
PlacentaChorionicgonadotropin
Anterior pituitary
Stimulates release of FSH and LH
Testes TestosteroneGeneral andreproductive structures
Develops and maintains male sex characteristicspromotes spermatogenesis
Testes InhibinAnterior lobeof pituitary
Inhibits FSH release
Testes TestosteroneGeneral andreproductive structures
Develops and maintains male sex characteristicspromotes spermatogenesis
Duodenal mucosa
Secretin PancreasStimulates secretion of pancreatic juice
Duodenal mucosa
Cholecystokinin GallbladderStimulates release of bile by gallbladder
