types of hormones

follicle stimulatiing hormone

• F = follicle production

• M = sperm production

• anterior lobe

  

lutenising hormone

• F = ovulation

• M = testosterone production

• anterior lobe

  

grwth hormone

• Body grows

  • particularly skeleton

• Maintainance of body organs

• Rate of protein synthesis

• anterior lobe

• gh

  

thyroid stimulating hormone

• Production and release of thyroid hormones

• anterior lobe

• tsh

  

adrenocorticotropic hormone

• Production and release of adrenal gland (cortex) hormones

• acth

• anterior lobe

  

prolactin

• anterior lobe

• prl

• Initiate and maintain breast milk secretion

  

oxytocin

• posterior lobe

• OT

• F = uterine muscle contractions

• Milk let down reflex

• M = contractions of vas deferens

  

antidiuretic hormone

• posterior lobe

• adh

• Causes kidneys to reabsorb water

  • Returns to bloodstream

• Can constrict arterioles

  • Increase blood pressure

    

melatonin

• pineal

• Regulates sleep patterns

• Production stimulated by the dark, inhibited by light

  

thyroxine

• t4

• thyroid gland

• Controls the metabolism

• Breakdown and synthesis of complex molecules -> cellular metabolism

• Breakdown of molecules releases energy

  • Some as ATP - cell activity

  • Some in heat - body temp

    

parathyroid hormone

• thyroid

• PTH

• Release triggered by low levels of calcium in the blood

• Body responds to:

  • Absorbing more calcium in food in the small intestine

  • Releasing calcium stored in bones

  • Releases calcium in renal tubules

    

thymosins

• thymus

• Group of hormones

• Influences maturation of T lymphocytes

  • Type of white blood cells needed for immune response

    

corticosteroids

• cortex of adrenal glands

aldosterone

• one of main corticosteroids

• Acts on kidneys to reduce sodium increases potassium in urine

  

cortisol

• one of the main corticosteroids

• Promotes normal metabolism

• Helps withstand stress and repair or damadged tissue

  

adrenaline

• one of main corticsteroids

• medulla of the adrenal glands

• Epinephrine

• Fight or flight response

  

noradrenaline

• medulla of the adrenal gland

• Norepinephrine

• Similar to adrenaline

• Mainly increases rate and force of adrenaline

  

insulin

• endocrine pancreas gland

• Increases uptake of glucose by cells from blood

  • Lowers blood glucose levels

• Converts to glycogen

  • Storage form of fat or glucose in liver and skeletal muscle

    

glucagon

• Opposite of insulin

• Breakdown of glycogen to glucose

  • Or fat to glucose

    

androgen

• testes

• Testosterone

• Development and maintenance of male sex characteristics

  

oestrogen

• Development of female sex characteristics

• Regulates menstrual cycle

• ovaries

  

progesterone

• ovaries

• Regulates menstrual cycle

• Regulates pregnancy
