Reproductive System Flashcards
The power stroke in the smooth muscle that will allow for seminal flow will be facilitated by what structure? Why?
The seminal vesicle secretes fructose which can be converted to ATP
What structure of the male reproductive system secretes a milky, slightly acidic fluid containing citric acid, acid phosphatase and several proteolytic enzymes?
The prostrate gland
If you are male and having difficulty urinating, or are urinating frequently, what could be the problem?
Prostatitis
How many varieties of apples exist?
Over 6000
What do proteolytic enzymes in the semen do?
Seminal liquefaction
With age, male ears, noses and prostrates enlarge. When the prostate enlarges to a symptomatic level it is called…
BPH Benign Prostatic Hyperplasia
The Cowper’s glad is also called ____________, and produces _____________________.
Bulbourethral; mucus for lubrication and an alkaline substance that neutralizes acid
Seminal fluid functions to:
- transport sperm/help with motility
- provides nutrients to sperm
- neutralize the vagina
5 min after ejaculation the semen ____________ because of ____________, then 10-20 min later it is ____________ by ____________.
Coagulates; clotting proteins; re-liquefy; PSA and other proteolytic enzymes
Semen fertility is affected by:
- abnormally shaped sperm
- sperm motility
- low count
The three erectile tissue masses of the penis contain:
- blood sinuses
- endothelial cells
- smooth mm
- cxn tissue
Which erectile tissue mass of the penis is paired? Which is unpaired?
Paired - corpus cavernosa
Unpaired - corpus spongiosum
The four anatomical parts of the penis are:
- root (bulb + crura)
- body
- glans penis
What does the tunica albuginea layer encase?
Corpus cavernosa and spongeousum of the penis
The ext urethral sphincter is controlled by what type of mm?
Skeletal
What colour was Bassam’s tie on male reproductive day?
Forest green? Teal green? Simply dark green? I don’t know, the circumcision talk is happening.
Process of erection is controlled by what nervous system? How does it happen?
PNS; vasodilation through nitric oxide, veins are compressed so blood is trapped
Ejaculation is controlled by what nervous system? How does it happen?
SNS; mm contraction closes sphincter at base of bladder, peristaltic contractions down the semen rabbit hole, ischiocavernous and bulbospongiosus promote emission
What is our quiz, taking place on Monday July 27th, covering?
The male reproductive system diagrams
When the paper towel runs out, who is our conduit messenger? What does that make him?
John; either nitric oxide or a penis
Rate your knowledge level of mitosis and meiosis
Yeah, you could still use review.
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
C E A F D B
What is the single conduit for semen to exit the testes?
Ductus epididymis
Where do sperm mature?
Ductus epididymis
Soren can be stored for 1-2 months, in which time it is either __________ or ____________
Expelled; degenerated and reabsorbed
Sperm motility increases over a _________ period
2 week
Where is sperm stored? (hint: this structure also propels them toward the urethra during ejaculation)
Ductus (vas) deferens, aka seminal duct
What does the spermatic cord contain?
- ductus deferens
- testicular artery
- autonomic nerves
- veins and lymphatic vessels
- cremaster mm
What’s happening with pale ischemia (of balls or any tissue)?
The artery is occluded
What is happening with red ischemia? What happens if it occurs over an extended period of time?
The vein is occluded; necrosis
Which gonadal vein is more likely to occlude? Why?
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
The seminal vesicles and ducti deferens come together to form the ____________, which functions to _____________.
Ejaculatory ducts; eject spermatozoa into the prostatic urethra
What three subdivisions is the urethra subdivided into?
Prostatic, membranous and spongy (cavernous)
What type of epithelium is the ductus (vas) deferens? Why?
Pseudostratified columnar epithelium, covered with a heavy coating of mm; convey sorry by peristaltic contractions, stored sperm remain viable for several months
What tube passes through the prostate?
Urethra
How are men like birds?
Their excretory duct also functions reproductively
In a vasectomy, what duct is cut and tied?
Vasectomy
What complication makes an inguinal hernia painful?
Fecal obstruction
What anatomical feature allows for inguinal hernias?
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
What’s the difference between an indirect an a direct hernia?
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
I don’t care where you are, interpretive dance an inguinal hernia right now.
Look at ch’yo bad self! You’ll never forget that now!
What component of seminal vesicle secretion contributed to sperm motility and viability? A - semenogelin B - nitric oxide C - prostaglandins D - fructose (pronounced frUCK-tose)
Prostaglandins
What protein causes coagulation of semen after ejaculation? A - LH B - FSH C - GnRH D - semenogelin
You better have gotten that. I’m not even going to tell you the answer.
Have you studied the diagrams? What male anatomy structure are a pair of pouch like organs posterior to the base of the bladder?
Seminal vesicles
What do seminal vesicles secrete?
An alkaline, viscous fluid containing fructose, prostaglandins and cloying proteins
What is hydrocele?
Collection of fluid in the tunica vaginalis (male)
What is the tunica vaginalis? The tunica albuginea? Which is internal to the other?
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
