diagram idea (Amazing Anatomy Information)

How about a good in-house diagram of the penis including all the relevent PE parts eg.ligs,tunica,corpora cavernosa,corpus spongiosum etc with click-on pointers about each part to already existing forums on Thunders.What do ya think?

I think it sounds good.

I will post something today.

I think this idea is totally rad.

It’d be better in 3D though :D

I think it’s a great idea! How about this; it should be a realistic seperate 4 view diagram(top, bottom, left side, right side), as well as a regular full view of the penis. I also think it should be an internal diagram showing the ligs cc ,cs, and tunica. It should also be posted as a seperate icon at the top of each forum page. This way when you are reading a post about targeting a specific area you can go to the top of the page and click on to have a better idea and see exactly what is discussed in the post. If possible the diagrams should include the pubic bone. Doing it this way IMO would help to be able to adapt an exercise and use it to its best effectiveness. It would provide a great training tool.

b1,

I think that would be helpful to many of the Members here :up:


Loved going to Cuba! :)

I'm surprised that Americans can't go because their government says they can't!

Check this thread

I posted diagrams of the male anatomy when the board first opened. Check it out, it’s all there.

Hope that helps.

Penis Anatomy

Photo anatomy

I’ve read some questions in different forums regarding blood flow within the penis and some of the replies have been on target, but a few show a misunderstanding of the penile anatomy. While I’m not a “hanger” and have not fully explored the Hanger’s Forum, I’ve read a few questions about what exactly gets stretched while hanging. Here are a couple random thoughts and some information about the penis which may help answer some of those questions.

Terms

  • glans - the “head” of the penis, normally covered by the prepuce (foreskin) it is abnormally exposed by circumcision
  • body - the “shaft” of the penis mainly containing two corpora cavernosa and the corpus spongiosum
  • urethra - the tube through which urine and semen exit the body, contained within the corpus spongiosum
  • meatus - [me-ate’-us] the opening of the urethra at the end (usually) of the penis, an abnormally placed meatus is called “hypospadias.”
  • scrotum - the “ball sack” or “nut sack,” a pouch of skin that contains the testicles. It is separated into two chambers by a septum so your testes and supporting structures don’t get twisted around each other.
  • corpus spongiosum - a sheath of spongy tissue which fills with blood during an erection and surrounds the urethra, usually abbreviated “CS.” It expands at both ends. At the base the expansion is called the “bulb” of the penis. At the other end it is called the glans. Blood within the CS can flow freely between the bulb and the glans.
  • corpus cavernosum - one of two (plural is “corpora cavernosa”) tubes of spongy tissue that fill with blood during an erection, usually abbreviated “CC.”
  • tunica albuginea - a tough sheath of connective tissue in two layers, one surrounds each corpus cavernosum and forms the septum between the two, the other layer surrounds the the CC and the CS. The spongy erectile tissue in the CC would not cause an erection without the tunica because the skin covering the shaft is able to expand. Because of its tough fibrous nature, the tunica resists further expansion after the CC are filled with blood and, under the pressure of the contained blood, forms the rigid structure that is an erection.
  • deep fascia (Buck’s fascia) - the deep fascia of the penis is a connective tissue sheath that surrounds the CC (and tunica), the CS, and the major nerves, arteries and veins of the penis. The superficial dorsal vein of the penis is outside this sheath. The deep fascia extends from the corona of the glans to the fascia covering the pubic bone and is covered by the skin.
  • fundiform ligament - this ligament supports the penis in a sling-like fashion. It originates in the lower abdominal wall and splits to surround the base of the penis where it attaches to the deep fascia.
  • suspensory ligament - this strong band of tissue originates at the pubic bone and splits to connect to the deep fascia of the penis. It does not attach to the tunica.
Head Enlargement

The glans is the expanded end of the corpus spongiosum (CS). The blood in it does not communicate with the blood in the corpora cavernosa (CC). This explains why some men have a firm glans during an erection and others do not. It depends on the amount of blood present in the CS and that can be different for each individual depending on his particular vascular (arteries and veins) anatomy. Squeezing the CC may exert pressure on the CS, which in turn may force some small amount of blood into the glans, but squeezing the CC themselves does not move blood into the glans. Ulis, Horses and other squeeze exercises are mainly for girth and only indirectly contribute to glans growth by this transmission of pressure to the CS. SadSack’s squeeze/stroke technique may cause an expansion of the head by moving a small amount of blood up the CS with each stroke, but it does not directly force blood into the glans from the CC.

At the base of the penis, the CS expands into the “bulb” of the penis. Pressure on the bulb will force blood into the glans. You can do this by performing the Kegel exercise or by pushing in with your fingers just under the scrotum (with a full or partial erection). You’ll see a much bigger expansion of the glans that way than by squeezing the shaft of your dick. I have yet to read about a “bulb squeeze” exercise for glans expansion. Could this be developed into a new exercise for those wanting a larger glans?

Attached is a photo from an online cadaver anatomy course (which I’ve altered by adding text) that shows the penis without the skin or fascia. The CC and CS (with attached glans) are clearly visible. Do not follow the link if seeing a cadaver (dead person) or penis without skin will bother you. (Here is a drawing from Gray’s Anatomy that shows essentially the same thing for those not interested in the photo.) By looking at the photo (or drawing) you will see that the corpora cavernosa and the glans are completely separate and blood cannot flow from one to the other. This separation should be kept in mind when you are planning which exercises to perform based on your desire to enlarge the glans or stretch the tunica.

Lig Stretch

Both the fundiform and suspensory ligaments are attached to the deep (Buck’s) fascia, not to the tunica. A properly applied hanging device will pull on the fascia and help stretch both the fascia and ligaments. An improperly attached device will pull on the skin. Stretching of the tunica probably does not result from hanging because the tunica/CC are attached to the lower pelvic bones. The ligs are attached in a manner that prevents the crura (the two ends of the CC inside the body) from receiving any of the hanging force until the ligs themselves are stretched beyond their normal limit of extension.

There are many online explanations of penile anatomy. Here is one of the better ones.

westla90069,

Pretty cool. Did you write this? Couple things that are kind of cloudy.

>fundiform ligament - this ligament supports the penis in a sling-like fashion. It originates in the lower abdominal wall and splits to surround the base of the penis where it attaches to the deep fascia.

suspensory ligament - this strong band of tissue originates at the pubic bone and splits to connect to the deep fascia of the penis. It does not attach to the tunica.<

Might be a little confusing. The deep fascia attach the ligs to the tunica. A fascial sheath is on top of the tunica and fascia are attached to the tunica.

>Lig Stretch

Both the fundiform and suspensory ligaments are attached to the deep (Buck’s) fascia, not to the tunica. <

Same as above.

>Stretching of the tunica probably does not result from hanging because the tunica/CC are attached to the lower pelvic bones.<

Makes no sense. Why not? The tunica can be stretched on its own as with any other collagenous tissue. Also, the collagenous tissues where the tunica is attached within the body may be stretched.

*************************************************

Gray’s

The fundiform ligament springs from the front of the sheath of the Rectus abdominis and the linea alba; it splits into two fasciculi which encircle the root of the penis. The upper fibers of the suspensory ligament pass downward from the lower end of the linea alba, and the lower fibers from the symphysis pubis; together they form a strong fibrous band, which extends to the upper surface of the root, where it blends with the fascial sheath of the organ. 7
The body (corpus penis) extends from the root to the ends of the corpora cavernosa penis, and in it these corpora cavernosa are intimately bound to one another. A shallow groove which marks their junction on the upper surface lodges the deep dorsal vein of the penis, while a deeper and wider groove between them on the under surface contains the corpus cavernosum urethræ. The body is ensheathed by fascia, which is continuous above with the fascia of Scarpa, and below with the dartos tunic of the scrotum and the fascia of Colles.

Maybe it is just perception.

Hey Bigger,

Yes, it’s my words trying to condense and simplify the medical terminology. You are correct that the deep fascia is connected to the tunica. My point, albeit a minor one, was that the ligaments are not directly attached to the tunica. Not really important in the big scheme of things.

From the Boston University site (link in original post): “Proximally, Buck’s fascia is attached to the perineal membrane; distally, it is tightly attached to the base of the glans penis at the coronal sulcus, where it fuses with the ends of the corpora… Buck’s fascia has a dense structure and is composed of longitudinally running fibers; it is firmly attached to the underlying tunica albuginea and encloses the deep dorsal vein, dorsal arteries and dorsal nerves.”

Makes no sense. Why not? The tunica can be stretched on its own as with any other collagenous tissue. Also, the collagenous tissues where the tunica is attached within the body may be stretched.”

I guess my point was that the suspensory ligament, initially, has a limit. That it will allow the penis to be pulled from the body only so far and that limit prevents the base of the crura of the corpora, which are attached to the inferior pubic rami, from receiving any stretch until the suspensory ligament is lengthened enough to allow it. That distance is probably different for each man. Men with low erection angles, perhaps, are those with longer suspensory ligs and they might be able to put a stretch on the entire length of the tunica. Those with tight suspensory ligs, and high erection angles, may not be able to put enough tension on the tunica to extend it until they have pulled out the ligs enough to allow it. Pehaps I’m not clear on the anatomy myself and the suspensory ligament and the tunica attachment are equal when it comes to longitudinal traction on the penis and both receive an equal pull.

Thanks for your input. I thought if I’d included inaccuracies, you would catch them. :)

westla90069,

It is a really good idea. Just those couple of cloudy areas.

>You are correct that the deep fascia is connected to the tunica. My point, albeit a minor one, was that the ligaments are not directly attached to the tunica. Not really important in the big scheme of things.<

Yes, it makes it a little confusing.

You are correct. For many, if not most guys, this susp lig stretch will allow a lot of ‘loose’ penis shaft to be pulled from the body. What I call the ‘internal anchor points’ are attached much better, and are tougher, and that is about where the easy gains stop.

>That distance is probably different for each man. Men with low erection angles, perhaps, are those with longer suspensory ligs and they might be able to put a stretch on the entire length of the tunica. <

EXACTLY! That is something I have been trying to explain for a while. I even have some terrible diagrams somewhere that explains this. But having the ability to stretch the tunica without lig interference is not a plus in the scheme of PE because this means there is probably little ‘inner’ penis to be exposed.

>Those with tight suspensory ligs, and high erection angles, may not be able to put enough tension on the tunica to extend it until they have pulled out the ligs enough to allow it. <

Great explanation, but this is a plus in the realm of PE. The high exit point that goes with high tight ligs usually indicate a lot of inner penis. The lengthening of the ligs allows this expression.

>Pehaps I’m not clear on the anatomy myself and the suspensory ligament and the tunica attachment are equal when it comes to longitudinal traction on the penis and both receive an equal pull.<

It depends. For a high exit point guy, at lower angles of pull, the tunica from the ligs on and the ligs receive the stress. At higher angles of pull, the entire tunica receives the stress and the ligs none.

For low exit point guys, the ligs may receive no stress whatsoever. A moot point.

This is a good thread in conjunction with the analysis of the tugback data I am performing now. I should be finished with it tonight.

westla90069 and Bib,

please don´t let this thread die or disappear guys! It´s the best I´ve read in a long time and it answered a few questions I had. I really think it should be a sticky.

westla90069,
could you expand a bit on the bulb-squeeze thing? I´ve tried to find a point which triggers head swelling like a kegel, but I can´t seem to find it.

Take care,

The bulb of the penis is an expanded end of the corpus spongiosum just like the glans. It’s location may vary a little from man to man, but I found mine in the perineum (the “taint” if you must use that term) a little less than half way between the scrotum and anus, closer to the scrotum. Pressing there gently while erect will force blood into the glans and increase its size more than it does by the Kegel maneuver alone. Perhaps pressing the bulb and gently and slowly stroking toward the glans might help expand those tissues like a Uli squeeze does for the corpora cavernosa.

Oops.

I should have said: Perhaps pressing the bulb with one hand and gently and slowly stroking toward the glans with the other hand might help expand those tissues…
