- This term has multiple meanings in the literature, all o which underscore its adaptive function. Here, defense response refers to sensory detection and multisubsystem, self-organizing arousal to tissue injury or threat of tissue injury. Related physiological changes facilitate fight, flight, or freezing. Although the defense response can mean the psychophysiological response to wounding the term incorporates the anticipation of wounding and appraisal of threat. The nervous system plays a strong role in defense by detecting threat in the external environment, cognition (anticipation, appraisal), signaling of incurred tissue injury, and through motor responses geared to escape or fighting. The endocrine system mounts a major physiological arousal response that maximizes the chances for survival, ie, the stress response. The immune system detects microbial invasion and toxins and initiates complex inflammatory responses that protects against microbial threat and promote wound healing. Thus, the term defense response designates purposeful, coordinated activity in 3 interdependent subsystems.
