Chapter 5 - Sexual Arousal & Response Flashcards
Pheromones
Chemical substances secreted externally by certain animals, which convey information to, or produce specific responses in, other members of the same species.
Erogenous Zones
Pares of the body that are especially sensitive to tactile sexual stimulation.
Primary Erogenous Zones
Erogenous zones that are particularly sensitive because they are richly endowed with nerve endings.
Secondary Erogenous Zones
Erogenous zones that become especially sensitive through experience.
Aphrodisiacs
Drugs or other agents that are sexually arousing of that increase sexual desire.
Anaphrodisiacs
Drugs or other agents whose effects are antagonistic to sexual arousal or sexual desire.
Antiandrogen
A substance that decreases the levels of androgens in the bloodstream.
Hormone
A chemical that is secreted directly into the bloodstream by a ductless gland, and which influences the functions of the body and/or behavior.
Estrus
A brief period of fertility that corresponds to ovulation.
Ovariectomy
Surgical removal of the ovaries.
Sexual Response Cycle
Masters and Johnson’s model of sexual response, which consists of four phases.
Vasocongestion
The swelling of the genital tissues with blood, which causes erection of the penis and engorgement of the area surrounding the vaginal opening.
Myotonia
Muscle tension.
Excitement Phase
The first phase of the sexual response cycle, which is characterized by erection in the male, vaginal lubrication in the female, and muscle tension and increases in heart rate in both males and females.
Sex Flush
A reddish rash that appears on the chest or breasts late in the excitement phase of the sexual response cycle.
Plateau Phase
The second phase of sexual response cycle, which is characterized by vasocongestion, muscle tension, heart rate, and blood pressure in preparation for orgasm.
Sex Skin
Reddening of the labia minor that occurs during the plateau phase.
Orgasmic Phase
The phase of the sexual response cycle that is characterized by a rapid succession of muscular contractions in the genital region of both males and females, and also by ejaculation by the male.
Resolution Phase
The fourth phase of the sexual response cycle, during which the body gradually returns to it’s pre-aroused state.
Refractory Period
A period of time following a response (e.g., orgasm) during which an individual is no longer responsive to stimulation (e.g., sexual stimulation).
Multiple Orgasms
One or more additional orgasms following the first, which occur within a short period of time and before the body has returned to a pre-plateau level of arousal.
