Urogenital System Study Deck

ovaries/uterus

female sex parts

testes/penis

male sex parts

urogenital system

the system that includes all organs involved in reproduction and in the formation and voidance of urine

retroparitoneal

kidneys are surrounded by this mesentary

retroperitoneal

is behind the parietal peritoneum

bladder

a distensible membranous sac containing urine

ureter

either of a pair of thick-walled tubes that carry urine from the kidney to the urinary bladder (paired)

urethra

duct through which urine is discharged in most mammals

kidney

either of two bean-shaped excretory organs that filter wastes from the blood and excrete them and water in urine

medulla

PURPLE

ureter

RED

renal pelvis

ORANGE

renal pyramid

DARK BLUE

renal pelvis

LIGHT BLUE

renal artery and veins

blood supply to the kidneys

renal corpuscle

cluster of capillaries, the blood-filtering component of the nephron of the kidney

fibrous capsule

surrounds the kidney (outlines)

Hilus of kidney

"indentation" of kidney

cortex

contains renal corpuscle

medulla

contains collecting ducts

renala pelvis

common basin where urine drains out of kidney

females

is the urethra shorter or longer in males or females

ductus deferens

conveys spermatozoa

epididymis

maturing spermatozoa

adipose tissue

fat cells inside the kidney

ruminants

these have multiple renal cortexs for each renal pyramids

bladder sphincter

the sphincter muscle of the urinary bladder; made up of a thickened muscular layer of bladder around the urethral opening

made from smooth muscle and elastic tissue

bladder

pelvic portion of urethra

female portion of urethra

testis

produces spermatozoa

urogenital opening

YELLOW

urethra

RED

ductus deferens

ORANGE

epididymis

GREEN

testes

BLUE

inguinal canal

in males it is the passage through which the testes descend into the scrotum and it contains the spermatic cord

ductus deferens

identified by the ureter wraps around each other

cryptorchidism

failure to descend testes

gubernaculum

a fetal ligament attached to the caudal epididymis and guides testis and the bottom of the scrotum

spermatic fascia

the outer most connective tissue layer of the scrotum, slippery on the outside

cremaster muscle

muscle layer that lines the scrotum, continuous with abdominal muscles

parietal vaginal tunic

inside the scrotum, continuous of the parietal peritoneum

visceral vaginal tunic

lines right against the testes

vaginal process

potential space inside the scrotum

head of epididymis

GREEN

ductus deferens

RED- joins the tail

tail of epididymis

YELLOW

body of epididymis

LIGHT BLUE

testicular vessels

DARK BLUE

pampiniform plexus

blanket network sitting on top of testicular artery snake like features, heat exchanger

testicular artery

a branch of the aorta supplying the testicles

ductus deferens, testicular vessels, testicular nerves, vaginal tunics

spermatic cord

cremeter muscle

associated with the spermatic fascia, muscle that is makihng up the spermatic cord

mesorchium

suspends the testis and pampiniform plexus

mesoductus

suspends the ductus deferens

visceral vaginal tunic

the walls surrounding direclty the pampiniform plexus

parietal vaginal tunic

the outer most layer of the scrotum

genital glands

aid passaes of spermatozoa and adds extra fliud and bulk to sperm

prostate gland

where the ductus deferens joins in with the urethra

corpus spongium

the urethra is surrounded by this layer of erectile muscle, responsible for enlargement, interacts with glands

glans of penis

the end of the penis

urethra

the narrow tube that in inside the penis and connects the bladder and ductus deferens together

corpus caverosum

additional muscules that help support the penis, anchors onto the pelvis

crus

the corpus cavernosum surrounded by white connective tissue sheath where they diverge and leads to the pelvis attachment

corpus cavernosum

will be most prominant in the caudal end of the penis

corpus spongiosum

will be most prominant in the cranial end of the penis

tunica albuginea

the white connective tissue surrounding the

bulbospongiosus muscle

covers the bulb of the penis (the base), responsible for releasing sperm out

ischiocavernosus muscle

covers the crura (one "leg" of the crus), connects to the ischium

os penis

in many mammals that reenforces the penis with a section of bone

prepuce

the outer most layer of skin surrounding the sheath of the penis

flaccid state

another word for non erect

cornified barbs on the surface glans

may be present in cats which "anchors" them when have intercourse

fibroelastic penis

present in sheep and cows, that is very fibrous and doesn't change much in diameter, has a sigmoid flexure

retractor penis muscle

smooth muscles that will help withdraw the penis back into the prepuce

infundibulum

hold the ovaries in place with the uretine tube, funnel-like
open end of the uterine tube

ovary

produces ova(eggs) and hormones in females

uterine horn

the two branches of the female reproductive system making up the base of the uterine tubes

cilia

lines the lumen of the uterine tube

fimbriae

finger-like processes fringing the infundibulum

ovary

DARK BLUE

infundibulum

RED

uterine tube

ORANGE

ovulation

when ova is released via the ovary, where fertilization takes place in the uterine tube

uterus

consists of paired horns (at the uterine body) and a central body

cervix

is the caudal, thick walled portion of the body of uterus, ball like shape, connects the uterus with the vagina

uterine horn

RED

cervix

GREEN

fornix

GREEN- depression around the muscular cervix

vulva

includes the labia (skin folds on either side) and clitoris (female equivalent to the penis)

vagina

RED

urethra

GREEN

vestibule

BLUE- the joining of the vagina and urethra
