Detailed explanation-2: -1. a state of physiological activation or cortical responsiveness, associated with sensory stimulation and activation of fibers from the reticular activating system. 2. a state of excitement or energy expenditure linked to an emotion.

Detailed explanation-3: -Psychological characteristics of arousal include feelings of vigor, energy, and tension. Physiological symptoms of arousal include increased heart rate and blood pressure, among other changes.
