Quiz 7: Sexual Response

Orgasmic phase

This phase involves a highly pleasurable response involving the feeling of physiological and psychological release from maximum levels of sexual excitement. The sympathetic part of the nervous system is most dominant in this phase

Research has shown, that during penetration additional clitoral stimulation is more than often (more than 70% of the cases) needed for orgasm to occur. (true or false)

True

When engaging in penetrative behaviors, it is important to remember that it often takes longer for the vagina and/or anus to reach the state where penetration is comfortable and pleasurable in comparison to the relatively short time it takes for the penis to become erect and ready for penetration. Communication is essential in this process making sure that sufficient levels of arousal and excitement have been reached before penetration begins to ensure that both the receiver and the inserter derives pleasure from the penetration. (true or false)

True

Due to lowers levels of __________ that are common after menopause or for some people on hormonal contraception, the vaginal walls tend to get dry and sometimes itchy.

estrogen

According to Freud, women experienced two types of orgasms:

mature vaginal orgasms, and immature clitoral orgasms

The Skene's glands are homologous to what tissue?

prostate gland

What are the two largest sex organs in the body?

skin and brain

Vaginal penetration may be uncomfortable or painful if the ________ has not yet occurred as this allows the vagina to widen and lengthen

tenting effect

From the two films about human sexual response, we learned that:

-The release of oxytocin during the orgasmic phase can cause mild to moderate mydriasis, which is the dilation of the pupils. -Penile ejaculation occurs in several spurts, the first or second spurt is typically the largest and can contain 40 percent or more of the total ejaculate volume. -A sex flush may appear during the excitement phase, usually on the cheeks of the face or the chest.

Possible erogenous zones include (but are not limited to)?

-anus -ears -neck -feet -genitals -breasts -inner thighs -mouth

The experience of an orgasm can be triggered by stimulation of the:

-anus -the mouth -penile glans -vagina -clitoris

Orgasm...

-involves rhythmic muscular contractions that include the myometrium of the uterus. -is often accompanied by penile ejaculation which occurs in two stages; emission and expulsion. -is not always essential for a pleasurable and fulfilling sexual experience

Ejaculation from the Skene's Gland:

-is thought to be associated with G-spot stimulation. -is expelled through the urethra -is not urine

According to Masters and Johnson, during the excitement phase of the sexual response cycle...

-the clitoris engorges with blood and becomes erect; most tumescence in females occurs internally. -vaginal lubrication occurs due to vasocongestion. -the penis becomes erect due to vasocongestion

What happens during the tenting effect?

-vagina widens -vagina lengthens -uterus pulls up

Masters and Johnson identified four stages of human sexual response. Please rank them in the correct order of appearance:

1. excitement 2. plateau 3. orgasm 4. resolution

About how long does the average orgasm last?

10-20 seconds

Penile ejaculation occurs in how many stages?

2

The medication Viagra is one of the most widely known prescription drug names on the U.S. market, and is often referred to as "the little blue pill". It is a tremendously popular drug used to help treat erectile dysfunction, and as a result, Pfizer, the medical company that sells Viagra earns about$2 billion annually in profit. The effective ingredient in Viagra is called, sildenafil citrate, what does this ingredient do?

Blocks PDE5

Which of the following organs have the sole purpose of producing pleasure?

Clitoris

Helen Singer Kaplan criticized Masters and Johnson's four-stage model of sexual response and stated that humans have what she refers to as a "brain appetite" for sex. To illustrate this, she developed a tri-phasic model of sexual response that included a phase to recognize this brain appetite, what is the name of this phase?

Desire

Resolution phase

During this phase, detumescence occurs. The pulse, heart, and respiratory rates drop, and muscles begin to relax. A deep sense of bodily satisfaction occurs. The parasympathetic part of the nervous system is most dominant in this phase

Plateau phase

During this phase, there is an increase in pulse, respiratory, and heart rates. The testes elevate closer to the body and there is an increased tenting effect. The sympathetic part of the nervous system is most dominant in this phase

Excitement phase

During this phase, tumescence begins causing the penis to become erect and the vagina begins to widen and lengthen. The parasympathetic part of the nervous system tends to be most dominant, particularly in the early stages of this phase

What is tumescence?

Engorgement with blood (vascular congestion) of the erectile tissues, marking sexual excitation, and possible readiness for sexual activity.

The refractory period is the recovery phase that is often associated with penile ejaculation. During this time it is physiologically impossible for penile erection and ejaculation to occur. The length of the refractory period will decrease with age. (true or false)

False

Masters & Johnson published their findings in a book that was released in 1966, what was their book about?

Human sexual response

What happens when the cremasteric reflex is triggered?

It causes the cremaster muscle to contract and elevate the testis
