sexual intelligence
involves self understanding, interpersonal sexual skills, scientific knowledge, and consideration of the cultural context of sexuality
the external genitals of the female including the pubic hair, mons veneris, labia majora, labia minora, clitoris, and urinary and vaginal openings
mons veneris
a triangular mound over the pubic bone above the vuvla
the foreskin or fold of skin over the cliotoris
a highly sensitive structure of the female external genitalia, the only function of which is sexual pleasure
shaft (female)
the length of the clitoris between the glans and the body
glans (female)
the head of the clitoris , which is richly endowed with nerve endings
the innermost tips of the cavernous bodies that connect to the pubic bone
a cheesy substance of glandular secretions and skin cells that sometimes accumulates under the hood of the clitoris
cavernous bodies
the structures in the shaft of the clitoris that engorge with blood during sexual arousal.
the area of the vulva inside the labia minora, both the urinary and vaginal openings are located within the vestibule
the tube through which urine passes from the bladder
the opening to the vagina
tissue that partially covers the vaginal opening
vestibular bulbs
two bulbs, one on each side of the vaginal opening that engorge with blood during sexual arousal
bartholins glands
two small glands slightly inside the vaginal opening that secrete a few drops of fluid during sexual arousal.
a streachable canal in the female that opens at the vulva and extends about 4 inches into the pelvis
the area between the vagina and anus in female and scrotum and anus in male.
collective term for the mucus membranes. moist tissue that lines certain parts such as penile urethra, vagina and mouth
the folds of tissue in the vagina
the engorgement of blood vessles in particular body parts in response to sexual arousal.
Grafenberg spot
glands and ducts in the anterior wall of the vagina. some women experience sexual pleasure, arousal, orgasm and an ejaculation of fluids from stimulation of the g spot
the small end of the uterus, located at the back of the vagina
the opening in the cervix that leads to the interior of the uterus
an instrument used to open the vagina walls during a gynocological exam,
a pear shaped organ inside the female pelvis , within which the fetus developes
the thin membrane covering the outside of the uterus
the smooth muscular layer of the uterine wall
the tissue that lines the inside of the uterine wall
Fallopian tubes
two tubes, extending from the sides of the uterus in which the egg and sperm travel.
fringelike ends of the fallopian tubes into which the released ovum enters
ectopic pregnancy
a pregnancy that occurs when a fertilized ovum implants outside the uterus, most commonly in a fallopian tube
female gonads that produce ova and sex hormones
the release of a mature ovum from the ovary
the sloughing off of the built-up uterine lining that takes place if conception has not occured
Menstral synchrony
simultanious menstral cycles that sometimes occur amoung women who live in close proximity
Follicle Stimulating hormone (FSH) - female
a pituitary hormone secreted by a female during the secretory phase of the menstral cycle. FSH stimulates the development of ovarian follicles. in males it stimulates sperm production
Luteinizing horome (LH)
the hormone secreted by the pituitary gland that stimulates ovulation in the female. in males it is called the interstital cell hormone (ISCH) and stimulates production of androgens by the testes.
Corpus luteum
a yellowish body that forms on the ovary at the site of the ruptures follicle and secretes progesterone.
pain or discomfort before or during menstration. primary dysmenorrhea is usually caused by the overproduction of prostaglandins. secondary is characterized by spasmic lower abdominal pain extends to lower back and thighs. can be caused by IUD, pelvic inflamitory disease, benign uterine tumors, obstruction of the uterine opening and endometriosis
hormones that induce uterine contraction
a condition in which uterine tissue grows on various parts of the abdominal cavity
the absence of menstration. anorexic or athletes often suffer from this. primary and secondary. women who experience athletic amenorrhea also have decreased estrogen levels.
physiological changes that occur during the transition period from fertility to infertility in both sexes.
the time period before menopause when estrogen is decreasing. usually starts around 40 years of age. 90% of women experience a change in menstral patterns and sexual response during this time period.
ceassation of menstration as a result of the aging process or surgical removal of the ovaries. mean age of 51
inflammation of the vaginal walls caused by a variety of vaginal infectoins. symptoms include: irritation or itching of the vagina and vulva, redness of the introitus and labia, unusual dishcharage, and sometimes a disagreeable odor. includes yeast infections, bacterial infections, and trichomoniasis
surgical removal of the uterus
surgical removal of the ovaries.
mammory glands
glands in the female breast that produce milk
surgical removal of the breast(s)
the portion of the penis that extends internally into the pelvic cavity
the length of the penis between the glans and the body
the head of the penis; it is richly endowed with nerve endings
cavernous bodies -male
the structures in the shaft of the penis that engorge with blood during sexual arousal
Spongy body
a cylinder that forms a bulb at the base of the penis, extends up into the penile shaft and forms the penile glans
the rim of the penile glans
a highly sensitive thin strip of skin that connects the glans to the shaft on the underside of the penis
male gonad inside the scrotum that produces sperm and sex hormones.
Spermatic cord
a cord attached to the testis that contains the vas deferens, blood vessles, nerves, and cremasteric muscle fibers
a condition in which the testis fail to descend from the abdominal cavity to the scrotal sac
Seminiferous tubules
thin coiled structures in the testis in which sperm are produced
Interstitial cells
cells located between the seminiferous tubules that are the major source of androgen in males
the structure along the back of each testis in which sperm maturation occurs
Vas deferens - male
a sperm carry tube that begins at the testis and ends at the urethra
male sterilization procesure that involves removing a section from each vas deferens
ejaculatory ducts
two short ducts located within the prostate gland
Urethra - male
the tube through which urine passes from the baldder to the outside of the body
Seminal vessicles - male
small glands adjacent to the terminals of the vas deferens that secrete an alkaline fluid (conducive to sperm motility) that constitutes the greatest volume of seminal fluid released during ejaculation
prostate gland
a gland located at the base of the bladder that produces about 30% of the smeinal fluid released during ejaculation.
Cowpers glands
two pea sized glands located alongside the base of the urethra in the make that secrete an alkaline fluid during sexual arousal (precum)
Semen or seminal fluid
a viscous fluid ejaculated through the penis that contains sperm and fluids from the prostate, seminal vesiclesand cowpers glands
the process by which the penis or clitoris engorges with blood and increases in size
Emission phase
the first stage of male orgasm in which the seminal fluid is gathered in the urethral bulb
Expulsion phase
the second stage of male orgasm during which the semen is expelled from the penis by muscular contractions
retrograde ejaculation
the process by which semen is expelled into the bladder instead of out the penis
genital retraction syndrom GRS
unusual culture bound phenomenon in which a male believes his penis is shrinking and retracting into his body
a widley used term for the genital retraction syndrom
a condition characterized by an extremely tight penile foreskin

Neuropeptitde hormones
chemicals produced in the brain that influence sexuality and other behavioural functions
a neuropeptide produced in the hypothalamus that influences sexual response and interpersonal attraction
