What hormones does the anterior pituitary secrete?

Prolactin
Thyroid Stimulating Hormone
Luteinizing Hormone
adrenocorticotropic hormone
Follicle Stimulating Hormone
Growth Hormone
Melanin Stimulating Hormone

Function of this hormone

Oxytocin

causes uterine contractions especially during labour

milk let down reflex in nursing mothers

Function of this hormone

Anti - duiretic

increase in water reabsorption in the collecting duct of the nephrons of the kidneys (when dehydrated)

Function of this hormone

Luteinizing hormone

stimulates ovulation
stimulates testes (makes sperm shape)

Function of this hormone

follicle stimulating hormone

helps to develop the primary follicles to be ready for ovulation
helps with production of androgen binding protein

Function of this hormone

Melanin Stimulation Hormone

stimulates melanin/pigment

Function of this hormone | Growth hormone

assist in growth via cell replication

Function of this hormone | Prolactin

Breast development | milk production

Function of this hormone | thyroid stimulating hormone

stimulates thyroid | controls production of T3/T$

Function of this hormone | T3/T4

Increase in metabolism, calcotin (blood calcium) | increase in body temp

Function of this hormone | Parathyroid Hormone

increase in blood calcium levels

Function of this hormone | Aldosterone - mineralocorticoid

blood pressure and sodium level

Function of this hormone | glucocorticoid

long term stress | increase blood sugar, supress the immune system, decrease in bone formation

function of gonadocorticoid

contribute to secondary sex characteristic

Function of this hormone | Adrenaline and Noradrenaline

increase heart rate, blood pressure, metabolic rate | short term response - fight and flight

Function of this hormone | Glucagon

increase blood glucose

Function of this hormone | pancreas

decrease in blood glucose | influences protein and fat metabolism

melatonin

involved in sleep processes | inhibits GnRH secretion from the hypothalamus

Adrenocorticotropic Hormone

Stimulates adrenal cortex

Insulin

Uptake glucose

Glucagon

Releases stored glucose

Aldosterone

Sodium reabsorption/Maintain BP/BV
