Panopto 32: Male Reproductive Flashcards
path the germ cells take as they move through the reproductive tract
lobules
seminiferous tubules
spermatozoa
straight tubules
rete testis
efferent ductules
epididymis
ductus deferens
seminal vesicles
prostate
semen
urethra
what is the testis covered by
tunica albuginea
What divides the testis into lobules?
connective tissue
what is found inside the lobules
coiled and twisted contents called seminiferous tubules
What do the walls of the seminiferous tubules produce?
germ cells that travel to the lumen of the seminifermous tubules
In the lumen, what state are the germ cells in?
free (not attached), non-motile and immature
Where do the convoluted tubules drain?
they drain from right to left into the non-convoluted tubules called straight tubules
What do the straight tubules do?
Drain the germ cells from the semiferous tubules to the rete testis.
What do the rete testis do?
The rete testis connects to another set of tubules called the efferent ductules.
What happens in the efferent ductules?
The non-motile germ cells leave; they are now outside the testis and in the head portion of the epididymis.
how long does it take for the germ cells to travel from the head to the tail of the epididymis?
2 to 4 weeks
What happens to the germ cells when they reach the tail of the epididymis?
The germ cells are fully mature and capable of motility and fertilization.
What portion of the epididymis are the germ cells stored in?
the tail surrounded by smooth muscle
How do the germ cells reach the ductus deferens?
Contraction of the smooth muscle in the tail of the epididymis pushes out the contents into the ductus deferens during ejaculation. This penetrates through the body wall through a passageway called the inguinal canal, eventually emerging into the abdominal cavity.
What happens when the germ cells reach the seminal vesicles?
mixes the seminal vesicle secretions with the germ cells as they pass through
