1

prostate gland

secretes portion of seamen

2

ductus deferens

contracts to propel sperm towards ejaculatory duct

3

urethra

semen passage to outside

4

germ cells

divide and differentiate to form sperm cells during spermatogenesis / gamete

5

sperm travels:

1. testis
2. epididymis
3. ductus deferens
4. ampulla
5. ejaculatory duct
6. prostatic urethra
7. membranous urethra
8. spongy urethra

6

semen (sperm cells & secretion from male reproductive glands)

1. seminal vesicles 60%
2. prostate gland 30%
3. testes 5% (sperm and spermatic duct secretions)
4. bulbourethral glands 5%

7

testis

exocrine (sperm-producing) and an endocrine (testosterone-producing) function

8

epididymis

final maturation of sperm

9

ductus deferens

forms part of spermatic cord

10

FSH

stimulates sperm & oocyte development

11

LH

release of testosterone / ovaries

12

GnRH

release of anterior pituitary hormones

13

oxytocin

causes uterine contractions

14

prolactin

milk production

15

primary oocyte

develop female gamete up through meiosis

16

functional layer

sloughs off during the menstrual cycle

17

menarche

first period bleeding

18

male accessory glands =
3 exocrine glands

- seminal vesicles
- prostate gland
- bulbourethral glands

19

ovarian cycle

1. follicular phase
2. ovulation
3. luteal phase

20

maturation and transformation of ovarian follicle

1. primordial follicle
2. primary follicle
3. secondary follicle
4. mature follicle
5. corpus lute
6. corpus albicans

21

menstrual

- spiral glands become necrotic, sloth into the uterine lumen
- necrosis of functional layer: necrotic endometrium, mucous secretions, small amount of blood released from spiral arteries make up the fluid
- constriction of spinal arteries
- contraction of uterine smooth muscle

22

hormone secretion in female

1. hypothalamus
2. pituitary gland
3. ovaries
4. uterus

23

oogonia

female stem cells gives rise to oocytes

24

acetylcholine
nitric oxide

(neurotransmitters) cause smooth muscle relaxation in the erectile tissue during erection

25

layer surround a primary oocyte:

zona pellucida

26

spermiogenesis = late spermatogenesis

differentiation of spermatid into a single, mature spermatozoon

27

spermatic cord includes:

- blood vessels/testicular artery and vein
- testicular nerves (autonomic nerve fibers)
- ductus (vas) deferens
- cremaster muscle

28

mammary glands

- organs of milk production
- located within breasts
- are modified sweat glands

29

interstitial cells / Leydig produce:

testosterone

30

what is hymen

membrane stretches across the vaginal outlet
