Q

paired dorsal erectile bodies bound by fibrous tunica albuginea

A

Corpora cavernosa

23
Q

Highly coiled tube; about 20 feet long, but only 1.5 inches long in its highly coiled condition; site of sperm storage (up to several months) and site where sperm undergo maturation to become fully functional and active reproductive cells.

A

Epididymis

24
Q

The duct of the epididymis has microvilli that:

A

Absorb testicular fluid 

Pass nutrients to the sperm

25
Q

Nonmotile sperm enter, pass through its tubes and become

A

motile

26
Q

Upon ejaculation the epididymis ?

expelling sperm into the

A

contracts

ductus deferens

27
Q

Ductus Deferens & Ejaculatory Duct: Runs from the ?through the ? into the ?

A

epididymis
inguinal canal
pelvic cavity

28
Q

Ductus Deferens & Ejaculatory Duct terminus expands to form the ? and then joins the duct of the seminal vesicle to form the ?

A

ampulla

ejaculatory duct

29
Q

Ductus Deferens & Ejaculatory Duct Propels sperm from the ? to the ?

A

epididymis to the urethra

30
Q

Conveys both urine and semen (at different times)

A

urethra

31
Q

urethra consists of three regions called

A

prostatic
membranous
spongy/penile

32
Q

Lie on the posterior wall of the bladder and secrete 60% of the volume of semen

A

Seminal Vesicles

33
Q

viscous alkaline fluid containing fructose, ascorbic acid, coagulating enzymes, and prostaglandins

A

semen

34
Q

Sperm and seminal fluid mix in the ejaculatory duct and enter the ? during ejaculation

A

prostatic urethra

35
Q

Doughnut-shaped gland that encircles part of the urethra inferior to the bladder

A

prostate gland

36
Q

function of prostate gland

A

Its milky, slightly alkaline fluid, which contains citrate, enzymes, and prostate-specific antigen (PSA), accounts for one-third of the semen volume
 Plays a role in the activation of sperm and dissolves clot 
Fluid enters the prostatic urethra during ejaculation

37
Q

Pea-sized glands inferior to the prostate

Produce thick, clear mucus prior to ejaculation that neutralizes traces of acidic urine in the urethra

A

Bulbourethral Glands (Cowper’s Glands):

38
Q

The hormone that enhances sperm motility

A

relaxin

39
Q

Prostaglandins (hormone-like substance) in semen: functions

A

Decrease the viscosity of mucus in the cervix  Stimulate reverse peristalsis in the uterus 
Facilitate the movement of sperm through the female reproductive tract

40
Q

Make female gametes

A

ovaries

41
Q

Embedded in the ovary cortex are ovarian follicles  Each follicle consists of an immature egg called an

A

oocyte

42
Q

one layer of squamous like follicle cells surrounds the oocyte

A

Primordial follicle

43
Q

two or more layers of cuboidal granulosa cells enclose the oocyte 

A

Primary follicle

44
Q

has a fluid-filled space between granulosa cells that coalesces to form a central antrum 

A

Secondary follicle

45
Q

follicle at its most mature stage that bulges from the surface of the ovary

A

Graafian follicle

46
Q
