- - - - secretes
        
        FSH
        
        stinulate follicle growth and estrogen production during menstural cycle
        
        LH
        
        stimulate ovulation and corpus lute formation
        
        control production of estrogen and progesterone from corpus luteum
        
        PRL
        
        Nontropic hormones
        
        stimulates lactation and growth of mammary glands and production of milk
        
        ACTH
        
        MSH
        
        skin pigmentation
        
        GH
        
        tropic and nontropic hormones
        
        promotes growth directly and diverse metabolic effects
      - controlled by RF and inhibiting hormones from hypothalamus
    - - secretes
        
        ADH
        
        osmotic pressure
        
        negative feedback mechanism: LESS WATER IN BLOOD→HYPOTHALAMUS→ADH→KIDNEY→DILUTE WATER→CONCENTRATE URINE
        
        enhances water reabsorption from collecting ducts in kidneys resulting less water in urine.
        
        ADH deficiency leads to syndrome of DIABETES INSIPIDUS production of large amount of clear urine
        
        OXYTOCIN
        
        positive feedback
        
        Release of milk
        
        induces utrine constractions
        
        suckling
  - - - thyroxine
        
        TSH
        
        tropic hormones
        
        stimulate metabolism
        
        Malfunctions of thyroxine
        
        Hypothyroidism
        
        Goiter
        
        Cretinism
        
        Hyperthyroidism
        
        Graves
      - calcitonin
        
        decreases the Calcium level of blood
        
        to balance calcium in the blood of mammals
  - - - norepinephrine
      - epinephrine
    - - corticosteroids
        
        Mineralocorticoid/Aldosteron
        
        reabsorbtion of sodium and water into the blood and excrete potassium
        
        low level of aldosterone result in ADISSON DISEASE
        
        salt and water balance
        
        Androgens
        
        small amounts of steroid sex hormones; estrogen progesteron and testosterone
        
        Glucocorticoids/ Cortisol
        
        stimulates production of glucose
        
        glucose metabolism and immune system
        
        high level of cortisol result in CUSHING SYNDROME
  - - - released
    - - precipitation of Ca with PO in kidneys cause kidney stones.
      - tetany is the result of low calcium level in the blood
  - - - Alpha cells
        
        glucagon
        
        Increases blood glucose level
        
        conservation of glycogen glycogen
        
        stimulate fat breakdown
        
        increases absorption of glucose in ileum
      - Beta cells
        
        Insulin
        
        conservation of glucose to lipids/glycogen
        
        increase permeability of cells
        
        decrease blood glucose level
        
        Diabetes mellitus
        
        Type (no insulin )
