Flashcards in Non-Testicular Structures of Male Reproductive Tract Deck (27):
1

where is most of the volume of ejaculate derived from

the seminal vesicles and prostate gland

2

what does the bulbourethral gland produce

a clear fluid that is released before ejaculation

3

what is the function of the fluid produced by the bulbourethral gland

lubrication of the urethra

4

what are the three segments of the urethra

prostatic, membranous and penile

5

what are the seminal vesicles

a sac with a coimplete array of folds lined by pseudostratified columnar epithelium and smooth muscle surrounding the folds

6

what do the ducts from the seminal vesicles join

the vas deferens

7

what does the joining of the seminal vesicles and vas deferens form

the ejaculatory duct

8

what does the ejaculatory duct pierce/empty into

the prostate gland and urethra

9

what surround the prostate gland

a thin fibromuscular capsule

10

what defines the capsule of the prostate

the fibromuscular septa that form spaces lined by a heterogeneous secretory epithelium

11

what is the urethra lined by

transitional epithelium

12

what does the urethra pass through within the prostate

fibrous stromal tissue at the centre of the gland

13

what other than the urethra passes through the prostate

the ejaculatory ducts

14

what does the prostate produce

a watery fluid

15

what are the three zones of the prostate

the transitional, central and peripheral zones

16

what is common in older men within the prostate

prostatic concecrations

17

what is characteristic of the skin of the penis

it has a richly vascularised subcutaneous layer with a fibrocollagenous capsule

18

what is the fibrocollagenous capsule of the penis known as

tunica albugina

19

what are the 3 erectile tissue within the tunica albugina

two corpora cavernosa and the corpus spongiosum

20

which erectile tissue does the urethra go through

the corpus spongiosum

21

which erectile tissue contains more erectile tissue

cavernosa

22

what is the penile urethra lined by

stratified columnar epithelium, chaning to non-keratinised stratified squamous near the tip of the penis

23

what does the erectile tissue consist of

blood sinuses surrounded by fibromuscular tissue containing smooth muscle

24

what are the blood sinuses of the penis supplied by

helicine arteries

25

where are the veins draining the blood sinuses of the penis

just below the fibrocollagenous capsule

26

what does parasympoathetic stimulation cause within the penis

dilation of the helicine arteries which causes the sinuses to become engored with blood (erection)
POINT

27

what does sympathetic stimulation cause within the penis

ejaculation
