pampiniform plexus

testicular artery

testicular nerve

21
Q

how long does it take for sperm to develop

A

2 weeks

22
Q

path of sperm

A
  1. seminiferous tubules
  2. rete tesis
  3. efferent ductules
  4. epididymis
  5. ductus deferens
  6. ampula
  7. ejaculatory duct
  8. prostatic urethra
  9. spongy urethra
23
Q

long flattened organ attached to the posterior of the testis

A

epididymis

24
Q

where is sperm stored until they are fully mature and capable of being motile

A

epididymis

25
Q

this undergoes muscular peristaltic contractions during ejaculation

A

ductus deferens (vas deferens)

26
Q

the terminal portion of the ductus deferens travels along the posterior portion of the bladder to form what

A

ampulla

27
Q

the ampulla joins with exits of the seminal vesicles to from what

A

ejaculatory duct

28
Q

what does the ejaculatory duct empty into

A

prostatic urethra

29
Q

what is the urethra subdivided into

A

prostatic urethra
membranous urethra
spongy urethra

30
Q

these secrete a viscous, whitish-yellow, alkaline fluid containing both fructose and prostaglandins

A

seminal vesicles

31
Q

provides fluid to support the sperm and is located at the base of the bladder. The urethra passes through its center

A

prostate gland

32
Q

benign hypertrophy of the prostate

A

enlarged prostate that compresses the urethra which exits the bladder

33
Q

how can you diagnose benign hypertrophy of the prostate

A

manual palpation through the rectum

34
Q

releases lubricating fluid out the urethra early in sexual excitation and prior to ejaculation. This can contain lost sperm that can impregnate a female

A

bulbourethral (cowpers) glands

35
Q

coitus interruptus

A

pull out method

36
Q

seminal fluid mixed with sperm

A

semen

37
Q

composed mostly of erectile tissue and when distended serves as the copulatory organ during intercouse

A

penis

38
Q

head of the penis

A

glans

39
Q

what is removed in circumcision

A

foreskin

40
Q

3 cylindrical columns of erectile tissue in the penis

A

corpus canvernosa penis (2)
corpus spongiosum penis

41
Q

this ensheaths the erectile bodies in the penis

A

tunica albuginea

42
Q

what is parasympathetic innervation is responsible for what in the penis

A

erection (point and shoot)

43
Q

sympathetic innervation is responsible for what in the penis

A

ejaculation (point and shoot)
