Flashcards in Reproductive Anatomy Deck (29):
1

5 layers of penis (from superficial to deep)

1. outer dermis
2. Superficial (dartos) fascia
3. deep (Buck's) fascia
4. tunica albuginea (encases erectile tissue and separates corpora cavernosa from corpora spongisum)
5 urethra

2

what structure does the male urethra run through

corpus spongiosum

3

pathway of sperm during ejaculation (6)

1. Seminiferous tubules
2. Epididymis
3. Vas deferens
4. Ejaculatory ducts
5. Urethra
6. Penis

4

which nerve is responsible for erection? what branch of NS

Pelvic n.--> parasympathetic

5

what substance is proerectile? which is antierectile?

1. NO--> increases cGMP --> SM relaxation and vasodilation
2. NE--> increases intracell Ca--> SM contraction/ vasoconstriction

6

what is emission

when sperm moves from testes to prostatic urethra to mix with seminal fluid

7

what nerve is responsible for emission? branch of NS

1. hypogastric n.--> sympathetic

8

what nerve responsible for ejaculation/ what branch of NS

1. Pudendal n.--> visceral and somatic nerves

9

connects cervix to side wall of pelvis

Cardinal ligament

10

connects ovaries to lateral pelvic wall

suspensory ligament of ovaries (infundibulopelvic ligament)

11

contains ovaries, fallopian tubes, and round ligament of ovaries

Broad ligament

12

connects medial pole of ovary to lateral uterus

Ligament of the ovary

13

contains ovarian vessels

Suspensory ligament of the ovaries (infundibulopelvic ligament)

14

contains uterine vessels

Cardinal ligament

15

3 pudendal nerve branches

1. inferior rectal nerve
2. Dorsal nerve of penis (or clitoris)
3. Perineal nerves

16

perineal nerves give rise to

posterior scrotal or posterior labial nerves

17

ovaries and testis drain to what lymph nodes

para-aortic

18

distal 1/3 of vagina/ vulva/ scrotum drain to what nodes

superficial inguinal nodes

19

proximal 2/3 of vagina/uterus drain to what nodes (imp; where vaginal or ovarian cancer would met)

1. obturator
2. external iliac
3. hypogastric nodes

*these not palpable

20

left ovary/testis drain to what vein

left gonadal vein--> left renal vein

21

right ovary/ testis drain to what vein

right gonadal vein--> IVC

22

what side is varicocele more common on and why

left--> venous pressure is higher due to the 90 degree angle the left gonadal vein connects to the left renal vein with

23

vagina has what kind of tissue

stratified squamous, non keratizined

24

ectocervix has what kind of tissue

stratified squamous

25

endocervix has what kind of tissue

simple columnar

26

uterus has what kind of tissue

simple columnar, pseudostratified tubular glands

27

fallopian tube has what kind of tissue

simple columnar, ciliated

28

ovary has what kind of tissue

simple cuboidal

29

what landmark is palpated for when giving pudendal nerve block in labor

ischial spine--> pudendal nerve runs right by it after coming out form underneath sacrospinous ligament
