Flight/fight response

In blood vessels these cause vasoconstriction. Blood vessels with i-receptors are present in the skin and the gastrointestinal system, and during the flight-or-fight response there is decreased blood flow to these organs. This is the reason people can appear pale when they have been frightened.

The overall importance of octopamine in insects is emphasised by the destructive influence of the formamidines and PIIs. Thus octopamine orchestrates appropriate behaviors and "prepares" the insect for stressful conditions. It mediates a "flight or fight" response. Disturbing octopamines homeostasis results in behaviors occurring at inappropriate times. Clearly a complete understanding of octopamine in insects may well lead to the development of... 

The circulatory system is controlled by epinephrine released into the circulation from the adrenal medulla, and NE released from nerve endings of neurons projecting from the locus ceruleus to the cerebral cortex, limbic system, and spinal cord. NE stimulates the conversion of glycogen to glucose in the liver, increases conversion of fats to fetty acids, and relaxes bronchial smooth muscles. These actions are part of the body s response to stress in what has been called the flight or fight response.

The sympathetic nervous system assists the body in managing the stresses and requirements of the external enviromnent. It is responsible for the "flight or fight" response. Reactions are constantly moderated and adjusted in response to information received by higher centers. Visceral function is fine-tuned Circulation, metabolism, smooth muscle tone, intestinal motility, cardiac function, and pulmonary response are regulated. 

Psychostimulants are able to induce a number of dose-dependent behaviour-activating features including the activation of fight-or-flight-type responses. A fine line can exist between therapy and potential for misuse or abuse and sometimes the differentiation appears to be somewhat arbitrary. Psychomotor stimulant pharmacology involves an augmented release of noradrenaline, dopamine, and to a lesser extent serotonin, into the synaptic cleft. Increased availability of monoamines is predominantly caused by inhibition of the corresponding monoamine...
