Reproductive System exam
1. What are the primary sex organs of the reproductive system?: •Primary sex organs
(gonads) - testes and ovaries
-Produce gametes (sex cells ) - sperm & ova
-Secrete steroid sex hormones
• Androgens (males)
• Estrogens and progesterone (females)
2. What is the different between gonads and gametes?: Gonads = sex organs
Gametes = sex cells
3. What are the accessory reproductive organs?: ducts, glands, and extern al genitalia
4. What does sex hormones play roles in?: -Development and function of reproductive organs
-Sexual behavior and drives
-Growth and development of many other organs and tissues
n scrotum) produce
5. What is the male reproductive system and its function?: •Testes (withi
sperm
,• Sperm delivered to exterior through system of ducts
6. How does sperm reach the outside?: -Epididymis (part of the testes) -> ductus deferens ->
ejaculatory duct -> urethra
7. What are the male reproductive system accessory sex glands?: -Seminal vesicles
-Prostate
-Bulbourethral glands
-Empty secretions into ducts during ejaculation
8. What is the pathway of sperm?: seminiferous tubules-->epididymis (where all the mature sperm
located)-->ductus deferens-->ampulla of ductus deferens-->seminal vesicles (1st gland secretion)-->ejaculatory
duct-->prostate gland (2nd gland secretion)-->bulbourethra glands (3rd gland secretion)-->urethra (once all three
glands secretion have been added to the sperm it now becomes semen and will travel out the male urethra)
minopelvic cavity
9. What is the scrotum?: Sac of skin and superficial fascia that hangs outside the abdo
-Contains the pair of testes
•3°C lower than core body temperature
• Lower temperature necessary for sperm production
,10. When talking about the scrotum what two muscles help regul
ate a constant
temperature for it?: -Dartos muscle - smooth muscle; wrinkles scrotal skin; pulls scrotum close to body
-Cremaster muscles - bands of skeletal muscle that elevate testes
11. Why can't sperm touches the male own blood?: The male immunity started to develop
during birth and they do not start to produce sperm until puberty which mean when since their immunity was develop
roughly 14yrs before their sperm does, their body does not recognized the sperm as "self". If sperm where to leak out
into the body and touches the blood it will be destroy by WBC.
12. What are the testes?: Male sex gland - produces testosterone in which a large number of sperm are
produced
• Sperm conveyed from (pathway of sperm until it get to he epididymis to be mature)
-Seminiferous tubules (sperm production begins here) ->
-Straight tubule ->
-Rete testis ->
-Efferent ductules ->
-Epididymis (Site where sperm mature sit)
13. What are the seminiferous tubules?: Where the sperm is produced and matured
• Interstitial endocrine cells in the soft tissue surrounding seminiferous tubules
• Produce androgens, e.g., testosterone (produce in the testes)
-Secrete it into the interstitial fluid
, 14. Where does blood supply come from to the testes?: •Blood supply
-Testicular arteries arise from abdominal aorta
ecting the testicles
15. What is the spermatic cord?: -A bundle of nerves, ducts, and blood vessels conn
to the abdominal cavity.
-Encloses nerve fibers, blood vessels, and lymphatics that supply testes
16. What happen when there is a homeostatic imbalance within the testes?: •Tes-
ticular cancer
-Rare; most common cancer in men 15-35
-Cryptorchidism (testes fail to descend outside complete into the scrotum/ outside of the body) is risk factor
-Sign - painless, solid mass in testis
-90% cured by surgical removal of testis and often radiation or chemotherapy
