Lesson 6C (Part 6) Flashcards
What are 8 examples of male reproductive organs?
- Testes
- Scrotum
- Ductus deferens
- vas deferens - Ejaculatory duct
- Seminal vesicles
- Prostate
- Bulbourethral glands
- Penis
What are the two male reproductive organ that is not located in the pelvic cavity?
- Testes
2. Penis
What is the primary male reproductive organ?
Testes
- paired
Scrotum
Suspends the testes in a sac of skin
What is each teste covered by?
By the tunica albuginea
Tunica albuginea
A tough, fibrous connective tissue
- covers the testes
What do extensions of the tunica albuginea create?
Inward projections that divide each teste into roughly 300 lobules
What do each lobule in the testes contain?
1-3 tightly coiled seminiferous tubules
Where does spermatogenesis take place?
In the seminiferous tubules
What superficially covers the testes?
The tunica vaginalis
What is the tunica vaginalis derived from?
Peritoneum
What is the visceral layer of the testes?
Tunica vaginalis
- 2 layers
Where do testes develop?
In the abdomen
Where is the testes blood supply and drainage?
In the abdomen
Why is it important for the testes to descend into the scrotum?
Because spermatozoa cant survive that warm temperature of the abdominal cavity
What do spermatids produce?
The seminiferous tubules
Where do the seminiferous tubules pass through?
The rete testis to the efferent ducts
Where does the seminiferous tubules go after the efferent ducts?
Into the epididymis
What happens to the seminiferous tubules once it reaches the epididymis?
They go through maturation and then storage
Epididymis
Is a flattened, tightly coiled tubular structure
Where is the epididymis located?
On the posterior surface of each teste
What is the epididymis continuous with?
With the ductus deferens
What does the vas deferens do?
It transports the sperm to the ejaculatory duct
What does the scrotum do?
It holds the testes
What is the scrotum divided by?
By the median raphe
- septum
Where do the testes drain?
Into the gonadal veins
- the right goes straight to the IVC
- the left goes to the left renal vein
What happens to the epididymis as it matures?
The coils become looser
