1

what doe the basic structure consist of?

- The primary sex organs: the testes
- various ducts/tubules : epididymis, vas deferens(sperm duct) and urethra
- Accessory glands: prostate gland,cowpers gland and seminal vessicles
- external genitalia : penis

2

What is structure and function of seminal vesicle?

S: sac-like glands
F: secrete sugary substance that is an energy source for sperm

3

What is the structure and function of the prostate gland?

F:
- produces milky alkaline fluid, make sperm more active
- Neutralises the acidic vaginal secretions and acidic PH of urethra

4

what is the structure and function of Cowper's gland?

S: a pair of small glands

F: secretions help to lubricate the head of penis, clear urethra of urine residues and maximise sperm motility.

5

What is the structure and function of vas deferens?

S: muscular duct

F: transports sperm by peristalsis from epididymis to the urethra

6

what is the structure and function of the penis?

S: made of erectile tissue that fills with blood, making penis erect.

F: Transfer semen to females vagina

7

What is the function of epididymis?

Stores sperm

8

What is the function of the testis?

Produce sperm and testosterone

9

What is the function of the scrotum?

Protects the testes
Regulates temperature, keeps testes 2 to 3 C lower than body temp for sperm production

10

What is the function of the urethra?

Transports semen and urine through the penis to exterior

11

What is the structure of the testis?

-Epididymis
- Seminiferous tubule
- Septum
- lobule

12

What is the function of the epididymis in the testes?

store sperm for 2-3 months, where it matures

13

What is the function of the seminiferous tubule?

where sperm are formed.
Tubules join to form epididymis

14

What is the function of the septum?

Divides testis into compartment or lobules

15

what is the function of lobule?

compartment in testis that contains one - three seminiferous tubules

16

What is the structure of the seminiferous tubules?

- Germinal epithelial cells
- Spermatogonium
- Primary spermatocyte
- Secondary spermatocyte
- sperm cell
- cell of sertoli
- spermatid
- interstitial cells (cells of leydig)

17

What is the function of the germinal epithelium cells?

divide to form new sperm cells

18

what is the function of the spermatogonium?

formed by mitosis of germinal epithelium; the start of sperm production

19

what is the function of a primary spermatocyte?

a mature spermatogonium ready for spermatogenesis?

20

what is the secondary spermatocyte?

haploid cell formed from the primary spermatocyte in the first meiotic division

21

what is the sperm cell?

Immature sperm cell formed by the maturation of the spermatids

22

what is the function of cells of Sertoili?

Provides food to developing sperm

23

what is a spermatid?

Formed from a secondary spermatocyte in second meiotic division

24

What are cells of Leydig and what is its function?

Endocrine cells that secrete testosterone.

25

what is the structure of the penis?

-Dorsal vein
- Dorsal artery
- erectile tissue
- connective tissue capsule
- erectile tissue

26

What is the function of the dorsal vein?

Carries blood away from the penis

27

What is the function of the dorsal artery?

Carries blood to the penis

28

What is the function of the erectile tissue?

Fills with blood, penis become erect

29

What is the function of connective tissue capsule?

Maintains erection by preventing blood leaving penis

30

What is the function of erectile tissue?

During erection, prevents urethra from being pinched closed , so stays open for ejaculation.
