A & P 2 Lab (reproductive)

1. Scrotum | temperature and regulation

2. Testes | produce sperm

3. Epididymis | maturation of sperm

4. Vas (ductus) deferens | transport sperm to ejeculatory duct

1. Seminal vesicles = produce 60% of semen

2. Ejaculatory duct = transport sperm to urethra

3. Prostate gland = produce 25% of semen

4. Cowpers gland = produce 10% of semen

1. Urethra

2. Corpora cavernosa } penis

3. Corpus spongiosum } penis

1. Ovary = produce oocytes (eggs)

2. Fimbrae = catch oocytes

3. Fallopian tube = fertilization site

4. Uterus

Uterus

1. Cervix

2. Endometrium = menstruation/implantation (targeted by estrogen)

3. Myometrium = labor (targeted by OT)

1. Vagina

2. Labia minor

3. Labia major

1. Clitoris

2. Mons pubis

3. Pubic symphysis

   targeted by relaxin

A = mammary gland (purple) | milk production ( targeted by PRL)

B v mammary duct (black line) | milk ejection = let down reflex (targeted by OT)

Cell = interstitial cells

Targeting hormone = LH

hormone produced = testosterone

Action of hormone = spermatogenesis (produce sperm)

Cell = spermatogonia

Cell = spermatid

Structure = primary follicle w/ primary oocyte

Targeting hormone = FSH

Hormones produced & their targets = estrogen targets endometrium

Action of hormones = regulate uterine cycle

Structure = mature follicle w/ secondary oocyte

Targeting hormone = FSH (LH surge = ovulation)

Hormone produced & their targets = Estrogen targets endometrium

Action of hormone = regulate uterine cycle

Structure = corpus luteum

Targeting hormone = LH & HCG

Hormone produced & their targets = estrogen & progesterone & relaxin

• estrogen / progesterone targets endometrium

• Relaxin targets pubic symphysis / cervix

Actions of hormone = regulate uterine cycle

• relaxin = relax

Process A > B = spermatogenesis

Where this occurs = seminiferous tubules of testes

A # of chromosomes = 46

B # of chromosomes = 23

Process A > B = oogenesis

Where this occurs = ovaries

A # of chromosomes = 46

B # of chromosomes = 23
