Q

Ejaculation is controlled by what nervous system? How does it happen?

A

SNS; mm contraction closes sphincter at base of bladder, peristaltic contractions down the semen rabbit hole, ischiocavernous and bulbospongiosus promote emission

Q

What is our quiz, taking place on Monday July 27th, covering?

A

The male reproductive system diagrams

20
Q

When the paper towel runs out, who is our conduit messenger? What does that make him?

A

John; either nitric oxide or a penis

21
Q

Rate your knowledge level of mitosis and meiosis

A

Yeah, you could still use review.

22
Q 
Put the seminal flow in the correct order
A - efferent ducts
B - ductus (vas) deferens
C - seminiferous tubules
D - rete testes
E - straight tubules
F - ductus epididymis
A

C E A F D B

23
Q

What is the single conduit for semen to exit the testes?

A

Ductus epididymis

24
Q

Where do sperm mature?

A

Ductus epididymis

25
Q

Soren can be stored for 1-2 months, in which time it is either __________ or ____________

A

Expelled; degenerated and reabsorbed

26
Q

Sperm motility increases over a _________ period

A

2 week

27
Q

Where is sperm stored? (hint: this structure also propels them toward the urethra during ejaculation)

A

Ductus (vas) deferens, aka seminal duct

28
Q

What does the spermatic cord contain?

A
  • ductus deferens
  • testicular artery
  • autonomic nerves
  • veins and lymphatic vessels
  • cremaster mm
29
Q

What’s happening with pale ischemia (of balls or any tissue)?

A

The artery is occluded

30
Q

What is happening with red ischemia? What happens if it occurs over an extended period of time?

A

The vein is occluded; necrosis

31
Q

Which gonadal vein is more likely to occlude? Why?

A

Left; it has a more vertical route to the inferior vena cava (vs the right which is more oblique) and therefore has a higher downward blood pressure

32
Q

The seminal vesicles and ducti deferens come together to form the ____________, which functions to _____________.

A

Ejaculatory ducts; eject spermatozoa into the prostatic urethra

33
Q

What three subdivisions is the urethra subdivided into?

A

Prostatic, membranous and spongy (cavernous)

34
Q

What type of epithelium is the ductus (vas) deferens? Why?

A

Pseudostratified columnar epithelium, covered with a heavy coating of mm; convey sorry by peristaltic contractions, stored sperm remain viable for several months

35
Q

What tube passes through the prostate?

A

Urethra

36
Q

How are men like birds?

A

Their excretory duct also functions reproductively

37
Q

In a vasectomy, what duct is cut and tied?

A

Vasectomy

38
Q

What complication makes an inguinal hernia painful?

A

Fecal obstruction

39
Q

What anatomical feature allows for inguinal hernias?

A

The weak portion of the anterior abdominal wall (mm) where the inguinal canal allows the spermatic cord to pass from the abdomen to the pelvis

40
Q

What’s the difference between an indirect an a direct hernia?

A

Indirect - the hernia/loop of intestine comes through the deep ring, or the top of the inguinal canal
Direct - the hernia/loop of intestine pushes through the posterior wall of the inguinal canal

41
Q

I don’t care where you are, interpretive dance an inguinal hernia right now.

A

Look at ch’yo bad self! You’ll never forget that now!

42
Q 
What component of seminal vesicle secretion contributed to sperm motility and viability?
A - semenogelin
B - nitric oxide
C - prostaglandins
D - fructose (pronounced frUCK-tose)
A

Prostaglandins

43
Q 
What protein causes coagulation of semen after ejaculation?
A - LH 
B - FSH
C - GnRH
D - semenogelin
A

You better have gotten that. I’m not even going to tell you the answer.

44
Q

Have you studied the diagrams? What male anatomy structure are a pair of pouch like organs posterior to the base of the bladder?

A

Seminal vesicles

45
Q

What do seminal vesicles secrete?

A

An alkaline, viscous fluid containing fructose, prostaglandins and cloying proteins

46
Q

What is hydrocele?

A

Collection of fluid in the tunica vaginalis (male)

47
Q

What is the tunica vaginalis? The tunica albuginea? Which is internal to the other?

A

Tunica (like a shirt) vaginalis (invaginated) - serous membrane derived from the peritoneum that partially covers the scrotum; tunica albuginea - dense white capsule creating 200-300 lobules/teste; albuginea is internal to vaginalis
