Part 1—Knowing Key Terms (4 points):
Fill in the blanks using key terms from the textbook and/or lecture notes.
-In the female, a pair of glands on either side of the urethra that
in some women may produce a fluid that is expelled during orgasm; also known
as the paraurethral glands.
-A widening of the inner two-thirds of the vagina during sexual arousal.
-The swelling of erectile tissues due to increased blood flow
during sexual arousal.
-In males, the buildup of sperm and semen in the urethral bulb just prior
to being expelled through the urethra.
-Masters and Johnson’s approach to explaining the process of sexual
response, encompassing four arbitrarily divided phases: excitement, plateau,
orgasm, and resolution.
-Mythical substances that are thought to enhance sexual arousal and
Dual Control Model of Sexual Response
-A theory that sexual arousal is
controlled by a combination of excitatory and inhibitory processes.
-In males, the sensation produced during the emission
phase of ejaculation that expulsion of semen is imminent, reflexive, and cannot be
stopped; often referred to as the “point of no return.”
-The fourth and last stage in the EPOR model, during which
sexual structures return to their unaroused state; also referred to as
Erotic Stimulus Pathway Theory
-A model of human sexual response based on
the psychological and cognitive stages of seduction, sensations, surrender, and
New View of Women’s Sexual Problems
-A model of female sexual response
incorporating a larger variety of factors than previous models, including physical,
cognitive, social, and relationships issues.
-The third stage in the EPOR model, during which sexual
excitement and pleasure reach a climax.
-The second phase in the EPOR model, during which sexual
arousal levels off (reaches a plateau) and remains at an elevated level of
-The first phase in the EPOR model, in which the first physical
changes of sexual arousal occur.
-In males, the contraction of pelvic muscles that force semen through
the urethra and out of the body through the penis.
-In some women, an area of tissue on the anterior (upper) wall of the vagina
that, when stimulated, may cause a woman to experience enhanced sexual
arousal and more intense orgasms.
Hypoactive Sexual Desire
-A persistently low level or lack of sexual fantasies or
desire for sexual activity; also known as inhibited sexual desire.
Kaplan’s Three-Stage Model
-An alternative to Masters and Johnson’s EPOR
