Brain-Body Pathways
• Two Brain-Body Pathways control our physiological responses to stress
1. The Catecholamine Pathway – hypothalamus activates sympathetic
system; adrenal glands release catecholamines that mobilize the body
for action.
2. The Corticosteroid Pathway – hypothalamus signals pituitary gland to
secrete ACTH; adrenal cortex to release corticosteroids that increase
energy.
