reproductive system Flashcards
What are the primary sex organs (gonads) for male and female?
testes and ovaries
What is the tunica albuginea?
A Pouch in the testes. white sheath = albuginea
What is the tunica vaginalis?
sac-like pouch of peritoneum that kind of cups the testes
What are the semineferous tubes?
tubular structures filling up the tunica albuginea
What is the function of the semineferous tubes?
to produce sperm
Where does the sperm go after its made in the semineferous tubes?
goes into the striaght tubes and then into the rete testis
What is the rete testis?
a channeling pool where the sperm gets deposited after the straight tubes and then is directed towards the efferent ductule.
What is the efferent ductule?
tubes that lead the sperm into the head of the epididymis
What is the epididymis?
comma shaped structure that sits along the superior and posterior aspects of the testes
What is the ductus deferens?
after the epididymis takes a hair pin turn at the most inferior point, it becomes the ductus deferens or the vas deferens.
-travels up the spermatic cord. where sperm travels.
What is the scrotum?
where the testes are held.
a sac of skin and muscle.
What is the dartos muscle?
smooth muscle intimately associated with the skin of the scrotum. when contracted, it crinkles the skin to thicken the scrotum and brings in the testes closer.
What is the cremaster muscle?
bands of skeletal muscle that extend inferiorly from the internal oblique muscles of the trunk. elevates the testes. VOLUNTARY CONTROLE
How do the testes sit in the body?
one is lower than the other.
What is the pampiniform plexus?
counter-current heat exchange
a plexus of venous structures that are taking the heat away from the arterial blood coming down.
-occurs in the spermaticord.
What are the male accessory glands?
seminal vesicles (2)
- prostate gland (1)
- bulbourethral glands
Describe the travel of the vas deferens
goes up the spermaticord, travels anterior to the pubic crest keeps going and then goes towards the bladder and travels over the superior aspect of the bladder and makes its way to the posterior aspect of the bladder and then drops inferiorly.
What is the ampula of the vas deferens?
an enlargement of the vas deferens at the posterior inferior end of the bladder.
How many ampula of the vas deferens do we have?
2 because we have 2 testes, 2 vas deferens
What combines with the ampula of the vas deferens? and what do the form?
the seminal vesicle; the ejaculatory duct we have two of them
Where do the two ejaculatory ducts dump into?
the prostatic urethra
What erectile tissue does the urethra travel through?
the corpus spongiosum
Where is the bulbourethral gland and what is its function?
found at the base of the penis (base of the erectile tissue) and it will produce a slippery slimy substance that will neutralize the acidic nature of the urethra due to the passage of urine.
