Q

increased FSH and LH levels in puberty lead to the release of _________ and _________

A

testosterone and estradiol

17
Q

testosterone and estradiol are responsible for ____________ _______ characteristics

A

secondary sex

18
Q

these are primarily responsible for pubic and axillary hair development

A

adrenal androgens

19
Q

in males, LH stimulates primarily what cell type?

A

leydig cells

20
Q

in males, FSH typically stimulates what cell type?

A

Sertoli cells

21
Q

where does speratogenesis occur?

A

testes

22
Q

spermiogenesis is the loss of ______ and formation of _______

A

cytoplasm
flagella

23
Q

the nucleus of the sperm contains what?

A

23 chromosomes

24
Q

the acrosome of the sperm contains what?

A

vesicle filled with oocyte penetrating enzymes

25
Q

the middle piece of the sperm contains what?

A

mitochondria to provide ATP energy

26
Q

Sertoli cells are stimulated by these 2 molecules

A

FSH
testosterone

27
Q

Sertoli cells also synthesize and secrete _______ into seminiferous tubules to bind testosterone to keep levels high for sperm development

A

androgen binding protein (ABP)

28
Q

Sertoli cells release ______ to inhibit FSH release without inhibiting LH release

A

inhibin

29
Q

what 3 structures produce semen?

A

1- seminal vesicle
2- prostate
3- bulbourethral gland

30
Q

why does BPH impact urination?

A

the prostate surrounds the urethra

31
Q

erection is due to what part of the the NS?

A

PS

32
Q

is emission and ejaculation sympathetic or PS?

A

sympathetic

33
Q

explain the positive feedback mechanism of an erection

A

blood fills penis–> compression of veins–> prevents blood from draining–> further maintains erection

34
Q

this is the accumulation of sperm cells and secretions of the prostae gland and seminal vesicles in the urethra

A

emission

35
Q

this occurs when skeletal muscles and the base of the penis contracts and forces semen out of the urethra

A

ejaculation

36
Q

what prevents semen and urine from mixing?

A

sympathetic constriction of urinary bladder internal sphincter during ejaculation
