  1. effects for cortisol
    • help with long term stress
    • protect against hypoglycemia
    • increase gluconeogenesis
    • breakdown of proteins
    • increase lipolysis
    • increase food absorption
    • surpress immune system
  2. cushing's syndrome
    • increase cortisol
    • hyperglycemia
    • hyperlipidemia
    • poor immune function
  3. complication of cushing syndrome
    • diabetes
    • arteriosclerosis/ heart disease
  4. symptoms of sudhing syndrome
    • moon face
    • abdominal fat with striations
  5. thyroid horomone functions
    • control metabolic rate and heat production
    • need it for growth
  6. thyroid gland diseases
    • hypothyroidism
    • grave's disease
    • hyperthyroidism
  7. hyperthyroidism
    • excessive thyroxin

    • symptoms: Exophthalmos (bulging eyeball)
    • treatment: medication, radiation & surgery
  9. hyperthyroidism effects
    • increase O2¬†and heat
    • increase protein catabolism (muscle weakness)
    • hyperexcitable reflexes (high HR)
  10. hypothyroidism effects
    • slow matabolic rate and O2
    • decrease protein synthesis (dont make down or making protein)
    • slow reflexes, slow speech and fatigue
    • improper nervous development
    • slow HR
  11. Hypothyroidism
    • decrease thyroxine
    • symptoms:
    • fatigue

    • thin nails
    • brittle hair
    • increase weight
    • -need horomone replacement
  12. growth depends on four factors:
    • growth horomone and several other horomone
    • diet
    • no stress
    • genetic potential for growth
  13. effect of growth horomone
    • increase plasma glucose
    • increase bone and muscle growth
    • increase protein synthesis
    • increase liver to secrete IGF's(insulin growth factor)
  14. hyperpituitarism
    • oversecretion GH
    • excessive growth bone and tissues
