Q

What is the function of GnRH and where is it released from?

A

Stimulates the anterior pituitary to release LH and FSH, it is released by the hypothalamus

24
Q

What 2 hormones are released from the anterior pituitary gland that affect male development?

A

lutenizing hormone and follicle stimulating hormone

25
Q

What is the function of LH in male development?

A

stimulates the release of testosterone from the cells of Leydig

26
Q

What is the function of FSH in male development?

A

stimulates sertoli cells to increase the rate of spermatogenesis

27
Q

Where is inhibin released from and what is its function?

A

it is released from the sertoli cells and it inhibits FSH

28
Q

What are the male sex hormones called?

A

androgens

29
Q

What is the most important male sex hormone?

A

testosterone

30
Q

What are the functions of testosterone?

A

development of male characteristics,

31
Q

What are three general principles of meiosis?

A

1) start with one diploid (2N) cell
2) One diploid (2N) becomes two haploid (1N) cells
3) two haploid (1N) become four haploid (1N) cells and are genetically different

32
Q

What are some differences between mitosis and meiosis?

A

Mitosis starts with one diploid cell and creates two more diploid cells (from basic cell division) that are genetically identical

33
Q

What is the function of the sustentacular cells or Sertoli cells?

A

support, nourish and regulate spermatogenic cells

34
Q

What is the function of the acrosome of a sperm cell?

A

help sperm penetrate the oocyte due to the enzyme it contains

35
Q

What is the function of the mitochondria of a sperm cell

A

provide ATP

36
Q

what is the function of the epididymus

A

support stored sperm and promote maturation

37
Q

what does the epididymis secrete?

A

glycogen

38
Q

What is the function of the ejaculatory duct?

A

combine fluids from vas deferens and seminal vesicles and take it to the prostate

39
Q

What is the function of the vas deferens?

A

transport sperm to the ejaculatory duct

40
Q

What all is secreted by the seminal vesicles and what is the function of these?

A

alkaline fluid- regulates pH; fructose- energy for sperm; prostaglandins- muscular contractions in female

41
Q

What is secreted by the prostate gland?

A

thin, milky, alkaline fluid

42
Q

What is BPH

A

benign prostatic hypertrophy

43
Q

What is secreted and what is the function of the bulbourethral glands?

A

mucus-like fluid, lubricates end of penis for intercourse

44
Q

What components make up semen?

A

sperm and secretions from seminal vesicles, prostate gland and bulbourethral glands

45
Q

What is the total volume of sperm cells in the amount of semen released at one time?

A

2-5 mL; 120 million sperm per mL

46
Q

What is capacitation?

A

activation of a sperm cell to fertilize an egg

47
Q

What are the three columns of erectile tissue?

A

corpora cavernosa, corpus spongiosum, tunical albuginea

48
Q

What is the glans penis?

A

enlargement of corpus spongiosum at the end of the penis

49
Q

Describe how an erection occurs

A

upon sexual stimulation, arteries that supply the penis dilate and blood enters the penile sinuses in the erectile tissue

50
Q

How do parasympathetic impulses aid in erection?

A

initiate and maintain an erection, and release nitric oxide

51
Q

How does the function of the sympathetic impulses in regards to erection?

A

causes the smooth muscle sphincter at the bladder to close, semen is propelled into the penile portion and powerful peristaltic contractions culminate the release of semen

52
Q

andr-

A

male, masculine

53
Q

ejacul-

A

to expel

54
Q

genesis-

A

to originate

55
