Document Summary
Brain-body relationships: the role of obesity (deborah schwartz) Autonomic ns: parasympathetic (rested state, slows body down) & sympathetic (non-essential fns on hold; stress response: quick response, unconscious, direct synapses from brain onto muscles. Hypothal secretes crh anterior pituitary releases acth . Adrenal cortex releases cortisol (recs everywhere strong effects) Increases body fat: regulates glucose (blood sugar) levels, helps to defend the body against infection, helps the body respond to stress. Hormone: a chemical msger produced in 1 part of the body & travels via blood to a target organ or cell: the target organ or cell has recs specific to certain hormones. Slower response: takes time for hormone to be created, excreted, to travel thru blood, systemic reaction any cell in the body can react to the hormone as long as it has the receptor for it. Sympathetic ns stimulates adrenal medulla ne, e systemic effects on multiple tissues. Beta cells in pancreas release insulin when blood-glucose.
