AP PSYCHOLOGY

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: -The current study found that cortical arousal tended to occur when HR was slower, suggesting that this HR-related brain activity is mediated by the parasympathetic, rather than the sympathetic, nervous system.

Detailed explanation-3: -Often called the emotional brain, the amygdala pings the hypothalamus in times of stress. The hypothalamus then relays the alert to the sympathetic nervous system and the signal continues on to the adrenal glands, which then produce epinephrine, better known as adrenaline.

Detailed explanation-4: -The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing. This system works automatically (autonomously), without a person’s conscious effort. Disorders of the autonomic nervous system can affect any body part or process.

Detailed explanation-5: -The sympathetic component tends to inhibit erections, whereas the parasympathetic system is one of several excitatory pathways. During arousal, excitatory signals can originate in the brain, either by the sight or thought of an appealing sexual partner or by physical genital stimulation.
