function of the testes

produce sperm and male hormones (testosterone)

function of the seminiferous tubules

produce sperm

function of the scrotum

keep the testes at the best temperature for sperm production

function of the epididymis

storage and maturation of sperm

function of spermatic cord

-Communication between the tests and the abdomen

-suspends the testes in the scrotum

function of the vas deferens

transports mature sperm to the urethra

function of the ampulla of the vas deferens

sperm stored here until ejaculation

function of the ejaculatory duct

drains seminal fluid into prostatic urethra

function of the urethra

carries urine from the bladder to the outside of the body

function of the seminal vesicles

holds the liquid that mixes with sperm to form semen

function of the prostate gland

secretes fluid that nourishes and protects sperm

function of the bulbourethral glands

secrete a mucous-like fluid which lubricates the urethra

Function of the corpora cavernosa

Expands to hold 90% of the blood involved in an erection, increasing both in length and in diameter.

function of corpus spongiosum

keeps urethra open during ejaculation

function of the ischiocavernosus

Move blood from crura into the body of the erect penis and clitoris

Function of bulbospongiosus muscle

empties male urethra

corpus spongiosum

function of the vaginal orifice

opening of the vagina

function of the external urethral orifice

opening of the urethra to the outside

function of the glans clitoris

Erectile tissue - fills with blood during arousal

function of the mons pubis

protection

enclose and protect the other external reproductive organs

function of the labia minora

forms margins of vestibule; protect openings of vagina and urethra

produce eggs and hormones

function of the fundus of the uterus

attaches to uterine tubes

function of the body of the uterus

provide nourishing environment for zygote

transport oocyte to uterus

function of the ampulla of the uterine tubes

primary site of fertilization

function of the isthmus of the uterine tubes

transport oocyte/zygote to uterus

function of the fimbriae of the uterine tube

capture the egg as it is released from the ovary

function of the vagina

entrance/exit from the uterus

function of the broad ligament

supports uterine tubes, uterus, and vagina

function of the mesovarium

suspends ovaries

function of the mesosalpinx

suspends/holds uterine tubes in place

Function of the mesometrium

supports the uterus

function of the ovarian ligament

connects ovary to uterus

function of the round ligament

attaches uterus to anterior body wall

function of the bulb of the vestibule

Erectile tissue - fills with blood during arousal

function of the crus of the clitoris

Erectile tissue - fills with blood during arousal

function of the corpora cavernosa

Expands to hold 90% of the blood involved in an erection, increasing both in length and in diameter.

function of the greater vestibular gland

secretes mucus into the vestibule, provides lubrication

function of the nipple

Discharge of milk, sucking, sensory

function of the areola

discharge sebum to protect nipple

function of the lobules of the mammary glands

produce milk

function of the lactiferous duct

transport milk from lobules to the nipple

function of the lactiferous sinus

store milk near the nipple

what opening of the vulva is most anterior

external urethral orifice

what opening of the vulva is most posterior

vaginal orifice

vagina-->cervix-->uterus-->isthmus-->ampulla

structures traveling through the inguinal canal in an xx individual

round ligament of the uterus

are xx or xy individuals more likely to have an inguinal hernia

xy because of the spermatic cord
