Lecture 29: Male Reproductive System

Question 1

is bladder retro or intra

Answer 1

retroperitoneal. peritoneum covers superior of bladder and base, reflects and starts to cover rectum. this forms the rectovesical pouch

Question 2

fxn testes

Answer 2

produce sperm and T

Question 3

epididymis fxn

Answer 3

the head receives sperm from seminferous tubules. maturation sperm. the tail continuous with VD

stores spemr for several months

highly convuluted ube

Question 4

vas (ductus) deferens

Answer 4

carries sperm from epididymis, goes behind urinary bladder

starts frmo tail epiidmys, ascends thru spermatic cord. ends at base urinary bladder

joins duct of seminal vesicle to form ejaculatory duct

Question 5

seminal vesicle

Answer 5

two coiled tube
produces 60% of fluid part of semen

joins the VD to form ejaculatory duct that opens into prostatic urethra

Question 6

major differences btw M and F repro

Answer 6

1. F repro is anatomically related to urinary system, M is not
2. most of F repro system is located within true pelvc cavity, whereas most parts of M are outside pelvic
3. F repro system connects peritoneal cavity with the exterior as a conduit, but M repro has no connection with peritoneal cavity

Question 7

what are the male repro ducts

Answer 7

epidydmis, VD, ejaculatory duct

Question 8

what are male accessory sex glands

Answer 8

seminal vesicles, prostate, bulbourethral gland

Question 9

structure testes

Answer 9

posterior border has hilum, blood, lymphatic, nerves travel thru

tunica albuginea covers testis, invaginates into its posterior border to form mediastinum of testis

250 lobules in each teste, each lobule contains 1-3 seminiferous tubules

Question 10

seminiferous tubules

Answer 10

produce sperm, devlier into epididymis

Question 11

developement of testes

Answer 11

develop in abdo cavity behind peritoneum. descend via inguinal canal, enter scrotum efore birth.m as testes go thru inguinal canal, they carry parts of ant abdo wall layers with them, surround them in scrotum. fforms the spermatic cord

Question 12

prostate

Answer 12

below bladder
behind pubic symphysis and in front of rectal ampulla
two ducts pass thru: urethra and ejaculatory duct, and they go into prostatic urethra

Question 13

bulbourethral gland

Answer 13

two small galnds on either side of membranous urethra

secretions during sexual arousal empty into spongy urethra to lubricate

Question 14

Answer 14

1. epididymis
   2.VD
   3.bulbourethral gland
   4.prostate
   5.ejaculatory duct
   6.seminal vesicle
   7.rectovesical pouch
   8.peeeeeen

Question 15

ejaculatory duct

Answer 15

formed by fusoin of lumen VD and seminal vesicle. joins to prostatic urethra

Question 16

rectovesical pouch

Answer 16

formed due to peritoneal reflection
lowest point of peritoneal cavity in M

Question 17

Answer 17

1.tail epididymis
2.body epi
3.ductus deferens
4.head epi
5.spermatic cord
6.rete testis
7.efferent ductules
8.septum
9.lobule
10.tunica albuginea
11. seminiferous tubule

Question 18

tunica albuginea

Answer 18

dense irregular connective tissue surrounding testis. sends septum into tissue of testes, divides into lobules

also covers columns of erectile tissue in penis

Question 19

how many lobules in testes? what is in them

Answer 19

250. each one contains 2-3 seminiferous tubules, which produce sperm and T

Question 20

efferent ductulrs

Answer 20

collects sperm.
comes together to form network at centre of testis= rete tesis

Question 21

efferent ductulrs

Answer 21

collects sperm.
comes together to form network at centre of testis= rete tesis

Question 22

rete testis

Answer 22

network of efferent ductulres in testi.

drains into epididymis

Question 23

three division of epididymis

Answer 23

head: receives sperm from seminiferous tubules
tail: continuous with VD
body

Question 24

what view is this? label

Answer 24

posterior view bladder

1.membranous urethra
2.prostatic urethra
3.prostate
4.ampulla of VD
5.ureter
6.VD
7.seminal vesicle
8.ejaculatory duct
9.pelvic floor
10.bulbourethral gland

Question 25

what is ampulla of VD

Answer 25

an enlargement of the vas deferens at the fundus of the bladder which acts as a reservoir for sperm

(#4)

Question 26

what 3 columnar structures make up penis

Answer 26

• Pair of corpus cavernosa
  
  • Corpus spongiosum (ventral surface)
    ○ Urethra passes through (penile urethra AKA spongy urethra)

Question 27

Answer 27

1. corpus cavernosa
2. corpus sponguiosum

three columnar structures of errectile tissue

Question 28

what is at center of corpus spongiosum

Answer 28

penile urethra (aka spongy urethra)

Question 29

what are columnar structures of penis attached to

Answer 29

pelvic floor and ischiopubic rami at the root of penis

remaining part (known as body) is freely movable

Question 30

root of penis

Answer 30

fixed.

formed by three masses of erectile tissue: a bulb in middle and two crura on each side
