. Describe the major physiological changes that occur in each stage of Masters and Johnson's model of sexual arousal. State the role of the parasympathetic and sympathetic
nervous systems in this process
The major physiological changes that occur in each stage of Master and Johnson's model of sexual arousal are the below. They were used to study a woman's sexual arousal.
1. Excitement - During the first stage the woman gets excited. Her female genitlia gets engorged with blood and get's lubricated. The woman's nipples might get hard and erect as well.
2. Plateau - If the sexual intensity continues, the female organ gets more and more sensitive.
3. Orgasm - Upon coontinued stimulation of the female genital in sensitive areas such as the G spot and the clitoris, the woman climaxes and tension is released. It involves pleasurable involuntary muscular contractions in the genital region and or the whole body.
4. Resolution - If stimulation stops, the body and sexual organs return back to normal.
The role of the Sympathetic Nervous System is to facilitate the sexual arousal of a woman during stimuation. In presence of a man or stimulus, it is the Symphatetic nervous system that facilitates the sexual arousal of the woman. The Parasympathetic nervous system facilitates the actual bodily changes that happens to a woman during sex like engorgement of the genitals, lubrication of the genital and erectness to nipples.
