The autonomic nervous system is a control system that acts largely unconsciously and regulates heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response and its role is mediated by two different components: the sympathetic nervous ...
Defense physiology is a term used to refer to the symphony of body function changes which occur in response to a stress or threat.. When the body executes the "fight-or-flight" reaction or stress response, the nervous system initiates, coordinates and directs specific changes in how the body is functioning, preparing the body to deal with the threat.

The EPPM outlines two primary appraisals an individual makes in response to a fear appeal: a threat appraisal, followed by an efficacy appraisal. Low threat appraisal When a threat appraisal is perceived to be low, i.e., there is a lack of imminent threat, the fear appeal is rejected immediately. Moderate to High threat appraisal
FFS is often referred to as the threat system.

The combination of perceived severity and perceived susceptibility is referred to as perceived threat. [7] Perceived severity and perceived susceptibility to a given health condition depend on knowledge about the condition. [4] The HBM predicts that higher perceived threat leads to a higher likelihood of engagement in health-promoting behaviors.
Antishock phase: When the threat or stressor is identified or realized, the body starts to respond and is in a state of alarm. During this stage, the locus coeruleus and sympathetic nervous system activate the production of catecholamines including adrenaline, engaging the popularly-known fight-or-flight response.
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire ...
Threat appraisal consists of the perceived severity of a threatening event and the perceived probability of the occurrence, or vulnerability. Coping appraisal consists of perceived response efficacy, or an individual's expectation that carrying out the recommended action will remove the threat, and perceived self efficacy , or the belief in one ...
