Flashcards in 5 LE Pelvic Viscera (Reproductive System) Deck (43):
1

rectum

end of digestive system
- begins S3
- ends @ tip of coccyx
- becomes anal canal below pelvic diaphragm
- blood supply: rectal artery

2

distal urinary system

ureters
urinary bladder
urethra

3

ureters

connects kidneys to urinary bladder

4

urinary bladder

holds urine b4 urination
- detrucer muscle
- blood supply: vesical arteries
- N: SNS (L1-L2) + PNS (S2-S4)

**adult bladder holds up to 1 liter of urine

**important for bladder control in spinal cord injury

5

location of urinary bladder in children (

completely in abdomen

6

location of urinary bladder in adults (empty)

in pelvis

7

location of urinary bladder in adults (full)

rises in greater pelvis + hypogastric region

8

female urethra

btwn clitoris + vagina
- 4cm long

9

male urethra

neck of bladder to external urethral orifice
- 18-22cm long
- parts: prostatic, membranous, spongy

10

scrotum

sac that encloses the testes
- "hangs" from the spermatic cord
- FCN: keeps tests @ 35˚ C (body T = 37˚ C)

11

spermatic cord

passes through inguinal canal to testes

12

scrotum contains

ductus defereus
testicular artery
lymphatic vessels
dartos + cremaster muscle
pampiniform venous plexus

13

cremaster y dartos muscles

contract when cold
relax when warm

**testes closer to or farther from body

14

pampiniform plexus

counteract heat exchanger so that blood to testes is 35˚ C

15

creation + passage of sperm

(1) testes - male gonads

(2) seminiferous tubules

(3) rete testis

(4) efferent ductules

(5) epididymis

(6) ductus (vas) deferens

16

male gonads

product sperm y testerone
- located in testes

17

vasectomy

cut ductus (vas) deferens
- severed + tied
- reversible but increases success if

18

cell types in testes

Leydig (interstitial) cells

Sertoli cells

19

descent of testes

from internal abdominal oblique to cremaster muscle
- gubernaculum

20

gubernaculum

tough cord that anchors testes in scrotal sac

**equivalent to (female) round ligament of uterus

21

seminal vesicles (2)

(male accessory structure) posterior to bladder
- oriented obliquely to prostrate
- joins ductus deferens to form ejaculatory duct

22

prostate

(male accessory structure) largest accessory gland
- btwn bladder neck + deep transverse perineal muscle
- size of walnut
- surrounds prostatic urethra

23

bulborethral (Cowper's) glands

male accessory structure

24

penis

copulatory organ
- outlet for urine + semen
- blood supply: internal iliac artery (branches)
- N: pudendal nerve

25

erectile tissues of the penis (3)

corpus spongiosum (1)
corpus cavernosa (2)

26

parts of the penis

root
bulb
shaft
glans

27

female external genitalia

mons pubs
labia majora
labia minora
clitoris
vaginal orifice
vestibular bulbs
vestibular glands
paraurethral glands

28

female internal genitalia

ovaries
uterine tubes
uterus
vagina

**enclosed in pelvic cavity

29

ovary

- size of almond
- female gonads (produce eggs/estrogen/progesterone)
- blood supply: ovarian artery

30

ovarian ligaments (3)

- suspensory ligament of ovary
- broad ligament of uterus (mesovarium)
- ligament of ovary

31

suspensory ligament of ovary

connects ovary to pelvic wall
- contains VAN

32

broad ligament of uterus (mesovarium)

connects ovary to uterus + uterine tube

33

ligament of ovary

connects ovary to uterus

34

uterine tubes (2)

fallopian tubes
- 10cm long
- upper border of broad ligament
- 4 parts
- blood supply: ovarian + uterine artery

35

uterine tube parts (4)

infundibulum (fibibriae)
ampulla
isthmus
uterine

36

most common fertilization cite

junction btwn ampulla + isthmus b/c very narrow

37

uterus

womb
- (empty) walnut
- (full term) watermelon
- 3 parts
- 3 layers
- blood supply: uterine supply

38

parts of the uterus

fundus (cap)
body
cervix (neck)

39

layers of the uterus

perimetrium

myometrium (muscle)

endometrium (sheds during menstrual cycle)

40

uterus support (3)

levator ani muscle
broad ligament
round ligament

41

round ligament

anchors uterus into labia majora
- homolog of (male) gubernaculum

42

vagina

copulatory organ
- distal portion of birth canal
- upper 1/2 = above pelvic floor
- greater/lesser vestibular glands
- blood supply: vaginal artery

43

greater + lesser vestibular glands

(vagina) secrete lubricating mucus
