or flight response is a response to a stimulus that could threaten the survival of an organism. During the fight or flight response the hypothalamus sends signals to the sympathetic nervous system. This causes the body to tense up and become more alert. The hypothalamus also releases CRF which activates the adrenal cortical system. The anterior pituitary gland begins the secrete adrenocorticotropic hormone directly into the bloodstream. When the ACTH reaches the adrenal cortex it stimulates the release

Panic Disorder . . . When the Wires Get Crossed in Our Sympathetic Nervous System It all begins when the heart starts racing and then pounds as if coming out of the chest.

of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The regulation of breathing is the result of a complex interaction involving a system of sensors‚ a respiratory control center‚ and an effector system to carry out its commands

Chronic Stress Chronic stress occurs when the body experiences so many stressors that the autonomic nervous system rarely has a chance to activate the relaxation response. (We were built to handle acute stress‚ not chronic stress.)
