- - - - One of the major functions of the hypothalamus is to maintain homeostasis,
      - The hypothalamus responds to a variety of signals from the internal and external environment.
    - - is at the base of the brain.
        
        Two parts
        
        Front Anterior
        
        TSH
        
        stimulates thyroid gland.
        
        ACTH
        
        stimulates the adrenal cortex part of adrenal gland.
        
        STH
        
        affects all the body cells.
        
        FSH
        
        Female
        
        stimulates ovarium.
        
        Male
        
        provides the creation of sperm cells.
        
        LH
        
        Female
        
        stimulates ovulation.
        
        Male
        
        stimulates testis.
        
        LTH
        
        provides the development of milk glands.
        
        MSH
        
        stimulates skin and provides the secretion of melanin.
        
        Back Posterior
        
        Oxytocin
        
        provides the contraction of uterus smooth muscles.
        
        ADH
        
        provides the reabsorption of water while the creation of pee.
    - - Thyroxine
        
        Lack of thyroxine hormone causes simple goiter and myxedema.
      - Calcitonin
        
        stimulates when the amount of calcium in the blood is excessive
        
        provides the transition of calcium from blood to the bones.
    - - Parathormon
        
        provides the balance between calcium and phosphate.
        
        provides the transition of calcium from bones to the blood.
        
        increases the calcium reabsorption from kidney.
    - - Outside of the gland cortex
        
        adrenal cortex
        
        cortisol
        
        increases the amount of glucose in blood.
        
        aldosteron
        
        provides the reabsorption of sodium and throwing of potassium.
        
        sex hormones
        
        androgen (testosterone and a small amount of estrogen)
      - inside of the gland medulla
        
        adrenal medulla
        
        adrenalin
        
        increases the blood pressure.
        
        increases the heart rate.
        
        increases the demolition in the liver and skeletal muscles.
        
        noradrenalin
        
        provides capillaries to narrow.
        
        increases the blood pressure.
    - - insulin
        
        decreases the level of sugar in the blood.
      - glucagon
        
        increases the level of sugar in the blood.
    - - estrogen
        
        increases mitosis in the cells of the uterus wall.
      - progesterone
        
        provides the hold of embryo to the uterus wall.
    - - produces testosterone hormone.
        
        provides the creation of sperm.
    - - Thymus
        
        is effective in the functioning of t lymphocytes.
        
        located in the chest area.
      - Pineal gland
        
        located between the brain hemispheres.
        
        produce melatonin hormone.
  - - - control self-perpetuating events that can be out of control.
        
        Example of Positive feedback
        
        Oxytocin hormone
        
        As the baby moves toward the vagina (birth canal), pressure receptors within the uterus and send messages to the brain to produce oxytocin.
    - - decreases the deflection from normal value.
  - - - Pancreas don't produce enough insulin or don't produce insulin.
    - - Body resists the effects of insulin.
    - - causes bones to become weak.
    - - occurs in the cells of the thyroid where just below your Adam's apple.It can grow rapidly or slowly.
  - - - Example of antagonistic mechanism
        
        Curare blocks binding sites for acetylcholine.
