PSL201Y1 Final: endocrine physiology
Document Summary
growth hormone enters blood and binds to growth hormone receptors on fat cell/adipocytes. this energy supplies the energy demands of exercise. *endocrine physiology = hormone action ((endocrine system controls body functions)) binding triggers signalling pathways within individual or groups of cells. the signalling pathways cause changes in cell activity. cell activity changes result in body function because cells communicated with each other and regulate body function. \body systems need to communicate with each other to regulate body function example: endocrine system and nervous system controls energy balance. *insulin action in the brain lowers liver glucose production in rodents obesity & diabetes. hypo = too little insulin => increased glucose levels, increased appetite. S binds to a receptor in the brain. S sends a signal via the efferent vagus that runs between the brain and liver. S binds to a receptor on the liver. Effects: controls glucose production, controls glucose levels by controlling production in the liver.
