Question | Answer |
---|---|
male internal reproductive organs | testes, epididymis, vas deferens, seminal vesicle, ejaculatory duct, prostate gland, bulbourethral glands |
structure of testes | paired, bilateral ovoid shaped suspended by spermatic cord, contained within scrotum |
function of testes | production of sperm & testosterone |
structure of epididymis | tightly coiled tube that emerges from top of each testis, leads to vas deferens |
function of epididymis | stores sperm cells until they mature |
structure of vas deferens | muscular tube passes along the medial side of the testis into abdominal cavity makes up spermatic cord ends behind urinary bladder |
function of vas deferens | transports sperm |
structure of seminal vesicle | convoluted, sac-like structure, 5 cm long attached to each vas deferens at bse of the bladder |
function of the seminal vesicle | secretes slightly alkaline fluid consisting of fructose & other nutrients for sperm cells produces 60% of volume of sperm |
structure of ejaculatory duct | short tube (1 inch) beginning at seminal vesicle & ending in the prostate gland |
function of ejaculatory duct | transport sperm & seminal fluid to urethra |
structure of prostate gland | firm structure the size of a chestnut composed of muscular glandular tissue |
function of prostate gland | secretes thin, milky, alkaline fluid which contributes to the motility of sperm |
structure of cowper's gland | 2 pea-sized glands under the male urethra |
function of cowper's gland | provide lubrication during sexual intercourse |
structure of scrotum | sac like 2 seperate chambers each chamber encloses a testis |
function of scrotum | provides a cooler home for the testes |
structure of penis | shaft is composed of 3 columns of erectile tissue -2 corpora cavernosa -corpora spongiosum |
function of penis | specialized to become erect for insertion into the vagina during sexual intercourse |
structure of ovaries | solid, ovoid shaped structures subdivided into 2 sections - medulla, cortex |
location of ovaries | lie bilateral to the uterus inferior to fallopian tubes |
function of ovaries | at puberty, they release progesterone & produce the female sex hormone estrogen releases a mature egg cell during the menstrual cycle |
structure of fallopian tubes (oviducts) | pair of ducts forms a funnel shaped region near the ovary called the infundibulum infundibulum surrounded by fringe of finger-like projections called fimbrae |
function of fallopian tubes (oviducts) | cilia along with peristaltic contractions of its wall move the egg cell on the uterus |
structure of uterus | muscular, hollow, shaped like an inverted pear uterine wall has 3 layers -endometrium -myometrium -perimetrium |
function of uterus | receives & sustains developing fetus capable of enlarging up to 500 times |
structure of vagina | thin walled muscular tube-like structure lined with mucous membranes |
funciton of vagina | receives the erect penis during intercourse converys uterine secretions transports offspring during birth |
structure of labia majora | large folds of fatty tissue extending from the mons pubis to the perinial floor |
function of labia majora | protects inner structures contains sensory nerve endings, secaceous & sudoriferous glands |
structure of labia minora | smaller folds, devoid of hair that merge anteriorly to form the prepuce of the clitoris |
funciton of labia minora | protect the openings of the vagina & urethra |
structure of clitoris | composed of erectile tissue |
function of clitoris | sexual arousal |
structure of vestibule | space enclosing the structures beneath labia minora |
function of vestibule | contains the clitoris, urethra, hymen, & vaginal opening |
paraurethral or Skene's glands | responsible for secretions of mucus & are similar to the male prostate gland |
Bartholin's glands or vestibular | lubricates the vagina for sexual intercourse |
perinuem | diamond shaped area from the symphysis pubis & extends to the anus region that contains the reproductive structures |
structure of mammary glands | located in subcutaneious tissue of the anterior thorax composed of about 15-20 lobes nipple surrounded by areola |
function of mammary glands | specialized to secrete milk following pregnancy under the influence of prolactin, milk is formed oxytocin allows the milk to be released |
