Hormonal Communication Flashcards
Type 2 diabetes
Body unable to respond to insulin effectively or beta cells don’t produce enough
Diet/ excerise
Type 1
Beta cells don’t produce insulin
Regular insulin injections
Hypoglycaemia
Blood glucose conc too low
Too much insulin injected
Lead to unconsciousness
Hyperglycaemia
-Blood glucose conc too high
-Too little insulin
-If untreated could lead to death
Stem cell treatment
Advantages-
- good donor availability as stem cell source = unlimited
- no need to take insulin injection
- less likelihood for reinjection
Stem cell transplant to treat diabetes
Transplant risk is greater than having diabetes
Immunosuppressant drugs needed for rest of life= more susceptible to infection
Adrenal medulla
Adrenaline and noradrenaline
Releases hormones when sympathetic nervous system is stimulated
Noradrenaline
Respond to stress
Adrenaline
Increases heart rate
Adrenal cortex
Androgens
Aldosterone
Mineralcorticoids
Glucocorticoids
Androgens
Male and female sex hormones
Aldosterone
Control blood pressure
Mineralocorticoids
Immune system regulation
Works with cortisol
Glucocorticoids
Corticosterone
Cortisol-
- regulate metabolism
- regulate blood pressure
- regulate cardiovascular response to stress
