If a patient is hypoglycemic, which of the following physiological processes will occur in an attempt to correct this situation? A). ACTH will be released by the posterior pituitary gland to stimulate the adrenal gland, B).glucocorticoid will be released by the adrenal cortex and increase serum glucose levels, C). mineralcorticoids will be released by the adrenal cortex and potentiate catecholamine effects, D). epinephrine will be secreted by the adrenal cortex in an attempt to increase blood serum glucose levels.
a) How does the body's hormonal response to short-term stress differ from the
body's hormonal response to long-term stress? In your answer, provide the names of
the hormones released, the glands from which they are released, and the effects on
the body.
b) Provide 2 reasons (as discussed in class) why long-term stress is harmful to our
physical health.
Tumors of the adrenal medulla, called pheochromocytomas, cause hypersecretion of catecholamines. Describe the expected signs and symptoms of this tumor.
