Human Sexuality

Front 1

Vagina

Back 1

tube shaped organ into which penis is inserted during coitus; receives ejaculate; birth canal; connects to cervix

Front 2

Cervix

Back 2

lower part of the uterus; flexible; expands during arousal

Front 3

Skene's gland

Back 3

female prostate; between wall of urethra and vagina; special erotic sensitivity; releases fluid into urethra

Front 4

Uterus

Back 4

holds and nourish developing fetus; 3 layers: endometrium (glands and blood vessels sloughed off during menstruation), myometrium (muscular, responsible for orgasmic and labor contractions), perimetrium (external cover)

Front 5

Fallopian Tubes

Back 5

tubes extending from uterus to ovary; pathway egg follows; fertilization occurs in infundibulum (area closest to ovary)

Front 6

Fimbriae

Back 6

finger-like projections toward ovary

Front 7

Ovaries

Back 7

two organs in the female that produce eggs and estrogen and progesterone; egg bursts out at each menstrual cycle and enters body cavity where fimbriae pick it up

Front 8

Penis

Back 8

sexual pleasure, reproduction, urination; tip: glans; shaft: main part; corona: raised ridge at end of the glans

Front 9

Corpora cavernosa

Back 9

spongy bodies running the length of the top of the penis; porous; hardened by blood during arousal

Front 10

Corpus spongiosum

Back 10

spongy body running the length of the underside of the penis; tissues of cavities that are filled with blood during erection

Front 11

Scrotum

Back 11

loose pouch of skin that contain the testes

Front 12

Testes

Back 12

gonads (reproductive glands; analogous to ovaries); manufacture sperm and testosterone

Front 13

Sperm

Back 13

mature male reproductive cell; capable of fertilizing egg

Front 14

Epididymis

Back 14

coiled tube where sperm mature located at the top and side of testes

Front 15

Vas deferens

Back 15

tube through which sperm pass on their way from testes and epididymis, out of scrotum, and to urethra

Front 16

Seminal vesicles

Back 16

saclike structures above prostate and produce about 60% of seminal fluid

Front 17

Prostate gland

Back 17

below bladder, secretes some of the fluid in semen; provide favorable environment for sperm and protects from acidity of vagina

Front 18

Cowper's gland

Back 18

glands that secrete a clear alkaline fluid in the man's urethra to neutralize acidity; site of pre-cum

Front 19

Kinsey Report

Back 19

Interview as wide of a variety of people as possible, with little regard to sampling (mostly well-educated white population living in the cities, Protestants); careful phrasing and establishment of rapport (example with the pimp); careful to keep anonymous and safe from possible prosecution; absence of probability sampling reduces accuracy (probability each member of society will have of being in sample), though refusals would still present problems

Front 20

NHSLS

Back 20

national survey using probability sampling for American patterns of sexual behavior; almost 80% response rate; face to face interviews with brief written questionnaires for sensitive topics; age range 18-59; minority group results not statistically significant

Front 21

Masters and Johnson

Back 21

recruitment of general population to have sex in lab; behavior and physiological responses observed and measured; participants interviewed (weeded out those with emotional problems or those too uncomfortable); might say something about the sexuality of those who elect to participate; also omitted sexually inexperienced; almost impossible to set up probability sample given high rate of refusal; practice round to be comfortable having sex in lab setting, physical responses then recorded for sexual intercourse, masturbation, and artificial coition (able to photograph inside via dildo); eliminates distortion, able to see what happens physically (though ignores emotional and experience aspect); may respond differently in lab setting

Front 22

Moser

Back 22

direct observation by attending S/M parties; advertised and rules communicated; did not obtain consent, though behavior was public

Front 23

Pituitary Gland

Back 23

region in brain that regulates levels of sex hormones

Front 24

Hypothalamus

Back 24

region of brain that regulates function of sex hormones (regulates pituitary)

Front 25

Follicle-stimulating hormone (FSH)

Back 25

hormone secreted by pituitary; stimulates follicle development in females and sperm production in males

Front 26

Luteinizing Hormone (LH)

Back 26

hormone secreted by pituitary, regulates estrogen secretion and ovum development in females and testosterone

Front 27

Menstruation

Back 27

shedding of endometrium, low P and E (triggered by sharp decline during luteal phase), high LH and FSH (day 1-5)

Front 28

Follicular Phase

Back 28

stimulation of follicles in ovary to bring egg to maturity; FSH increase, progesterone decrease; estrogen secretion which triggers next phase (day 5-14)

Front 29

Ovulation

Back 29

follicle ruptures, egg released, high levels of estrogen, inhibits FSH production, Estrogen triggers GnRH from hypothalamus which produces LH, low progesterone levels (day 14)

Front 30

Luteal phase

Back 30

LH stimulates follicle to turn to mass of cells which manufactures progesterone which thus inhibits LH; degeneration of mass thus lower levels of E and P; stimulates production of FSH (day 15-28)

Front 31

Gonad (embryonic source)

Back 31

homologous and analogous; ovaries and testes

Front 32

Genital tubercle (embryonic source)

Back 32

homologous and analogous (clitoris and glans penis)

Front 33

Genital swelling (embryonic source)

Back 33

homologous: outer lips and scrotum

Front 34

Müllerian Duct (embryonic source)

Back 34

homologous: degenerates in males, fallopian tubes, uterus, parts of vagina

Front 35

Wolffian Duct (embryonic source)

Back 35

Homologous: epididymis, vas deferens, seminal vesicles, degenerates in females

Front 36

Urethral primordia (embryonic source)

Back 36

homologous and analogous: prostate, Cowper's glands and skene's gland, bartholin glands
