What is the position of the female urethra

Answer 9

embedded into the anterior wall to the vagina

-at the perineal muscle

Question 10

What is the glandthat secretes a lubricant and changes the pH of the female urethra

Answer 10

periurethral gland

Question 11

What composes the male reproductive system

Answer 11

testes, ducts ( epididymis , ductus deferens, ejaculatory duct) , accessory sex glands (seminal vesicles, prostate and bulbourethral gland) and penis + scrotun

Question 12

What combines to form the ejaculatory duct

Answer 12

vas deferens and seminal vesicle’s duct

Question 13

where does the ejaculatory duct open to

Answer 13

prostatic urethra

Question 14

Where is the bulbourethral gland located

Answer 14

perineal muscle

Question 15

describe the relation of the vas deferens with the bladder

Answer 15

it is located near the sides of the urinary bladder and the base ( posterior) end of the urinary bladder

Question 16

What is the rectalvesical pouch

Answer 16

between the rectum and the bladder, deepest part of the peritoneum cavity in males

Question 17

Are testes glands?

Answer 17

yes

Question 18

How many surfaces, border and poles does the testes have

Answer 18

2 surface: lateral and medial
2 borders: anterior and posterior
2 poles: superior and inferior

Question 19

when the testes finishes it’s migration, what covers it, what does it leave behind

Answer 19

covers:3 layers of muscle,

leaves behind: inguinal canal (muscular tunnel)

Question 20

What is the tunica albuginea

Answer 20

fibrous capsule that surrounds the testis and it gives rise to the septum that enters the testes and divides the testes into lobules

Question 21

What is found in the lobules of the testes

Answer 21

seminiferous tubule

Question 22

What does the seminiferous tubule do?

Answer 22

produces sperms and delivers them to the epididymis

Question 23

How do we divide the epdidymis

Answer 23

head, body and tail, attached to the superior, posterior and inferior part of testes

Question 24

functio of epididymis

Answer 24

maturation of the sperm

Question 25

How long for sperm maturation

Answer 25

64 days

Question 26

Which part of the epididymis receives the sperm from the seminiferous tubule

Answer 26

head of epididymis

Question 27

Which part of the epididymis gives the sperm to the ductus deferens

Answer 27

tail of epididymis

Question 28

what is the course of the ductus deferens

Answer 28

it starts from the tail of the epididymis and ascends through the spermatic cord and ends at the base of the posterior surface of the bladder. enters the pelvic cavity

Question 29

What is the spermatic corde

Answer 29

it is the layer of 3 muscles that surround the ductus deferens, testicular vessel, nerve and lymphatics

Question 30

What is the dilation of the ductus deferens after it passes over the ureter

Answer 30

ampulla

Question 31

What does the ampulla connect to form the ejaculatory duct

Answer 31

ducts of the seminal vesicle

Question 32

Where is the start of the ejaculatory duct contained within

Answer 32

prostate gland

Question 33

What is the function of the bulbourethral gland

Answer 33

secretes fluid for sexual arousal - changes pH +lubricates

Question 34

function of the seminal vesicle

Answer 34

secretes most fluid of the semen, nourishes the sperm

Question 35

where does the bulbourethral glands open to

Answer 35

penile urethra

Question 36

what are the 2 parts of the penis

Answer 36

root and body

Question 37

what forms the root of the penis

Answer 37

3 erectile tissue (2 crura [crux of penis] and 1 bulb)

Question 38

where do the crux of penis attach to

Answer 38

ischiopubic ramus - provide support for the penis

Question 39

Where does the bulb of penis attach to

Answer 39

attaches to interior surface of the inferior surface of perineal muscle

Question 40

what is the continuation of the crux within the shaft

Answer 40

corpus cavernosa

Question 41

What is the continuation of the bulb within the shaft of the penis

Answer 41

corpus spongiosum

Question 42

what is the position of the corpora cavernosa and corpus spongiosium of the penis

Answer 42

corpora cavernosa: posterior aspect of the penis | corpus spongiosium: anterior aspect of the penis

Question 43

What happens the the corpus spongiosum become at the end of the shaft

Answer 43

enlargens to form the glans of penis and it covers the ends of the corpora cavernosa

Question 44

What covers the 3 erectile tissues of the shaft of the penis

Answer 44

tunica albuginea

Question 45

what is the function of the tunica albuginea of the testes

Answer 45

maintains the pressure of the penis as blood is pumped into it -maintains the erection

Question 46

What covers the glans of the penis

Answer 46

prepuce: double layer of skin

Question 47

function of ischiocavernosus

Answer 47

squeezes the crux of penis to the ischiopubic ramus (against this bone) drains the blood and maintains erection

Question 48

function of bulbospongiosus

Answer 48

squeezes the bulb ( passage of the urethra) helps drain last drops of urine
