scrotal sac (scrotum)
protective container;divided into two sacs by a frenulum; one testis per sac
cremaster muscle
in scrotum; contracts to pull the temperature sensitive testes toward the body; responds to temperature
dartos muscle
muscular folds in the scrotum; aind in maintaining temperature
spermatic cord
one per testis; collective it is all of the arteries, veins, nerves, lymphatic vessels, cremaster and dartos muscle, and vas deferens wrapped together in one bundle
seminiferous tubules
site where sperm is produced (spermatogenesis); connects to the duct system in the testes
male reproductive gamete, 50-150 million per ml of semen
male infertility
less than 20 million/ml
sperm and seminal fluid (2.5-5 ml per ejaculate
rete testis
a network of ducts that contain mature sperm cells
a single duct in each testis through which sperm passes
vas deferens
stars at the end of the epdidmus; comes out of the testes; 18 inches long; carries sperm to and connects with the urethra
ejaculatory duct
site of the union of duct from the seminal vesicle and vas deferens; it passes through the prostate; site of large peristaltic waves to propel sperm into the urethra
seminal vesicle
secretes thick fluid inot ejaculatory duct; adds 60% of semen volume
prostate gland
donut shaped gland under the urinary bladder; secretes more fluid into urethra (25%)
bulbourethral (Cowper's) gland
located uner the prostate; addes 15% of ejaculate; alters the pH of the urethra to be suitable for sperm
urethra (male)
common passageway for semen and urine
male copulatory organ; composed of erectile tissue called the corpus cavernosa that is highly vascular
arteriole blood fills the corpus cavernosa, causing it to press against veins, resulting in more blood entering than leaving and engorgement
corpus spongiosum
lines the penile urethra; keeps urethra open during ejaculation
glans penis
the enlarge tip (meatus) of the penis
prepuce (foreskin)
loose fitting skin covering the glans penis in uncircumcised men
main female reproductive organ; produce mature oocyte (egg); secrete estrogen, progesterone, and inhibin; almond shaped
uterin/fallopian tubes
surround the ovary and snatch up oocyte when it is released
fingerlike projections that help sweep the oocyte into the fallopian tube
opening of the fallopian tube about which the fimbriae are arranged
site of menstruation, implantation of fertilized ovum, development of fetus, and labor
opeing to the uterus
layers of the uterus
perimetrium, myometrium, endometrium
inner layer of uterus; highly vascular; site of embyro attachment (functional layer); shed during menstruation
vulva (pudendum)
general term for the external female genitalia
mons pubis
an elevation of fat tissue that cushions the pubic symphysis during childbirth; site of anterior pubic hair attachment
labia majora
two large folds of skin; homologus to the scrotum; help close the vagina
labia minora
medial to the labia majora; close the vestibule
the region between the labia minora, contains the hymen (if present) and vaginal orifice
small mass of erectile tissue and nerves; homologous to the glans penis in males
urethra orifice
opening to the urethra; only urine exits in females
secondary female sex characteristic; provide milk for newborns
site where milk emerges from the breast
dark circle surrounding the nipple
mammary glands
modified sweat glands that produce milk
suspensory ligament (Cooper's ligament)
support the weight of the breast; become loose with age and excessive strain
graafian follicle
a mature follicle containing a secondary oocyte
corpus luteum
remnants of the mature follicle after ovulation; degenerates if fertilization doesn't occur; produces progesterone if pregnancy occurs
corpus albicans
remnants of corpus luteum after implantation does not occur
