PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-2: -Generalized CNS arousal (GA) is the most elementary function of vertebrate nervous systems. It is a non-specific neuronal ‘force’ that activates ascending and descending systems, facilitating the initiation of any behavior responding to external stimulation and emotional expression.

Detailed explanation-3: -arousal of the autonomic nervous system, particularly its sympathetic nervous system functions, resulting in the physiological symptoms associated with anxiety and fear (e.g., sweating, palpitations, dry mouth, lightheadedness, upset stomach).

Detailed explanation-4: -Such primary arousal responses are largely governed by the sympathetic nervous system, but responses of the parasympathetic nervous system may compensate or even overcompensate for the sympathetic activity. Physiological arousal includes but is not limited to sexual arousal.
