Prostate Vs Bulbourethral gland

Members do not see this ad.

I have read Cliffs, destroyer and my AnP text, but I am still confused. So which gland releases Alkaline mucus to neutralize acidic vaginal secretions, Prostate or Bulbourethral gland. I had this question last year on my real DAT also. I am so confused...

bulborethral gland - that's what the princeton review says. Or, I mean, "that's what she said." 😉

haha! thanks. Wat do u think of 2010 destroyer # 341

In my anatomy book and on wikipedia says that the prostate gland secretes the alkaline fluid while the bulbourethral gland secretes pre-ejaculatory fluid for lubrication.

No the prostate gland releases the alkaline fluid to protect the sperm from the acidic nature of the female repro system

As quoted by http://www.celtnet.org.uk/cancer/prostate-gland-function.html

" The prostate secretes a liquid that contains a number of enzymes , citric acid and calcium. This fluid is added to the semen during ejaculation and since it is alkaline it is believed to protect the sperm in the hostile acidic environment of the vagina, thus aiding sperm motility and survival."

now i am 10x more confused!

Okay this is what the princeton review has in a chart labeled "Accessory Glands" for the Male Reproductive System.

Prostate Gland - mostly fructose and coagulant - fxn: nourishment, allows semen to coagulate after ejactulation (makes up 35% of total ejaculate volume)

Bulbourethral Gland - thick, alkaline mucus - lubricate urethra, neutralize acids in male urethra and female vagina (makes up 3% of total ejaculate volume)

Seminal Vesicles - mostly fructose - nourishment of sperm - 60% of total volume

Testes - sperm - 2% of total volume

So, I'm not sure what to say. Maybe I should shoot my prof an email who is an oncologist who works with prostate cancer patients. lol.

original poster - the fact that you are asking this question tells me that you are ready for this test

haha! why do u say so? Bio dental mom: I agree with you. Campbell states the same facts and Cliff says Bulbourethral/cowpers have unknown function!

Agree with all of that. One small addition, prostate gland secretes seminoplastin (antibacterial protein).

via Human A&P by Marieb:

Talking about prostate secretions "It plays a role in activating sperm and accounts for up to 1/3 of the semen volume. It's a milky, slightly ACID fluid that contains citrate (nutrient), several enzymes (fibrinolysin, hyaluronidase, acid phosphatase), and prostate-specific antigen (PSA)"

Talking about seminal vesicles "Stored within the mucosa's honeycomb of crypts and blind alleys is a yellowish viscous ALKALINE fluid containing fructose sugar, ascorbic acid, a coagulating enzyme (vesiculase), and prostaglandins, as well as other substances that enhance sperm motility or fertilizing power"

Talking about Cowpers glands (bulbourethral) "They produce a thick, clear mucus, some of which drains into the spongy urethra when a man becomes sexually excited and neutralizes traces of acidic urine in the urethra"

also, embryologically speaking, the prostate IS the bulbourethral gland (came upon this thread while searching for something related)

Do you mean all the prostate made from bulbourethral gland?

 

[Baylor2011]

flying forever: don't worry about it. isn't relevant for the dat lol

Bulbourethral gland

 

[dentz00]

It's the prostate gland page 211 in cliffs

Stop posting here if you don't know what you're talking about.

More evidence for the OP

via Campbells Bio 7th Ed

Seminal Vesicles - "Fluid from the seminal vesicles is thick, yellowish, and ALKALINE. It contains mucus, the sugar fructose (which provides most of the energy used by the sperm), a coagulating enzyme, ascorbic acid, and prostaglandins.."

Prostate gland - "..secretes its products directly into the urethra through several small ducts. Prostatic fluid is thin and milky;it contains anticoagulant enzymes and citrate (a sperm nutrient)."

Bulbourethral glands - "Before ejaculation, they secrete a clear mucus that NEUTRALIZES ANY ACIDIC URINE remaining in the urethra. Bulbourethral fluid also carries some sperm released before ejaculation, which is one reason for the high failure rate of the withdrawal method of birth control"

Seriously...research before you provide your "insight"

 

[Baylor2011]

Update: Biology 8th ed also has exactly what the 7th edition said.

What are you going to trust...Cliffs or the book that the test makers get their questions from?

CAMPBELL's!!!!!!!!!!!!

I mean they're homologous structures... the equivalent in the other sex... a guy's penis is the same thing as a girl's clitoris... they have the same exact origin, but that origin develops into 2 different organs depending on the sex, i.e. whether it's a dude or a dudette

other examples off the top of my head:

Testis vs. Ovary
Scrotum vs. Labia majora
Spongy urethra vs. Labia minora
Foreskin vs. Clitoral hood

there are many many more...
