Anatomy of the penis
Composition
The anatomy of the penis is composed of three cylinders completely separate of each other (reference to box 1.1). The two parallel cylinders, named corpus cavernosum, function to erect the penis. Both cylinders communicate with each other, approximately three-fourths of their length, via small holes between the penis’ cylinders. (This is the reason why penis injections are only given in the shaft or the cylinder.) These cylinders, when approaching the body, are parted and attached to the pelvic bone by a thick membrane. In addition, each cylinder is covered with a resistant wrapping known as the “tunica albuginea.” Circling the penis is another membrane, that when filled with blood under pressure, creates a firm formation and allows penetration.
The third cylinder of the penis is the so-called “spongiosum” of the collection, and contains the urethra. The fine tissue around the erect membrane is much finer, and the cylinder sits in the groove created by the other two cylinders. While the spongiosum approaches the end of the penis, it inflates. This is known as the balano. Finally, in the area closest to the male body, the spongiosum widens to form the bulb. Covering the three cylinders is a thick and resistant membrane named Buck’s girdle. Finally, there is a cap covering this area named Colles girdle or rather, the superficial cap. This continues up the wall of the abdominal area, that supports the structure firmly, at the same time producing strength and hardness.
The skin that covers the penis is extremely mobile and flexible. This is necessary to permit and produce erections. The penis’ skin is unique in this sense, and is controlled by the hormonal system. The Balloon is a distinct anatomic structure different from the rest, and is covered by foreskin. It has a double layer of skin, and is allowed to move and adjust itself according to the needs of the penis. Consequently, it is sensitive to any type of swelling or trauma. For this reason, the penis’ skin is susceptible to swelling by small trauma, within a short period of time.
The penis organ is anchored to the pubic bone, and the widening muscle connects, in turn, to the top of the penis. The muscles from the recto muscle, or the abs, are those that are found in the central abdominal wall. This growing layer is known as the fundiform ligament, which produces a lengthening of the recto muscle and connects to the penis. When they cut this ligament, as in operations of enlargement, the penis may seem larger; however, it is simply hanging lower from the body due to its greater mobility.
The blood source
The source that supplies the penis with blood is called the Aorta, which comes from a main vessel found in the lower part of the back body. The aorta divides into an internal and external artery. By sitting, and especially when riding a bicycle, a man can stop the circulation of blood to this general penis artery. When they damage it, blood shortage and erectile dysfunction usually follow. A main artery of the corpus cavernosum supplies blood to each one of the erect bodies of the penis.
The source that supplies the blood to the balano (also known as the head of the penis) forms part of the separated system that was mentioned above. Therefore, men can reach an erection without the balano swollen, for example, in known conditions as priapismo, and for men that have penis implants for balano that will not enlarge.
The mechanism underlying an erection is the corpus-venoso-oclusivo. When the veins cannot compress or block themselves, it is impossible to achieve an erection. Without this extremely sensitive mechanism, blood can escape prematurely from the penis and result in a lost erection. This dysfunction is called venous escape.
Nervous System
The nervous system of the penis is involved in the creation and maintenance of an erection, as well as ejaculating. The sensor nerves are found in the greatest numbers in the head of the penis. In order to reach an erection it takes multiple areas of the brain and the spinal cord. The first part of a penis erection is controlled by the brain, known as the mental erection. This occurs under any type of mental or erotic stimulus. Erections that can only be caused by the friction of the skin is known as reflexogenica erection. It occurs commonly among men that have had some type of damage in the spinal cord. Most men with reflexogenica cannot achieve an erection unless they are stimulated physically.
Sperm
The scrota is a special structure with very fine skin that hangs and doesn’t usually have much hair. Saving the testicles outside the body produces an environment more appropriate for the creation of sperm. The heat tends to prevent sperm from developing incorrectly. Underlying the scrota’s skin is the cremasterico muscle. It connects to the scrotum and contracts, elevating the testicles. This is done in response to extremely cold or hot temperatures, as well as harmful or painful stimulus’s.
The testicles are rough and shaped like a small egg. They are responsible for the development of sperm as well as the fabrication of the testosterone hormone. Behind the testicles is the epididymis, a single tube in a spiral shape where the sperm matures and is stored. At the end of the epididymis there is a thick muscular tube named vas deferens. The vas deferens bring sperm from the epididymis to the prostate to ejaculate. Vas deferentia are usually cut in surgeries of sterilizing and vasectomy.
The sperm go inside of the vas deferens, into two structures found behind the prostate. These structures are called the seminal vesicles, and are rough glands approximately 5 centimetres in length. The seminal vesicles form a secretion, supplementing the sperm and uniting with it at the prostate. The prostate creates a liquid that supplements and activates the sperm. The first intention of the seminal vesicles and the prostate is to proportionally supply and give a place for the sperm to exist before the ejaculation. Spermatozoids are really a small component, consisting of less than 5%, and is why there aren’t substantial changes following vasectomy.
The prostate segregates the majority of the liquid. Two small glands are situated right outside urinal genital diaphragm. These structures, names the bulbouretrale glands, produce a quantity very small of clear liquid. This is the clear liquid that we see right before the ejaculation. It may also contain small amounts of spermazoid, too.
Abnormal Structures
An example of a structure problem is the curve of the penis. This curve is named congenital and can be present from birth, or can be acquired. The majority of men have a slight curve or lightly bent penis. This is not considered abnormal. A curve is considered abnormal when it interferes with penetration. A penis too substantially curved to penetrate is rarely found. However, in such a situation, the curve is generally found in a position downwards with one corpus cavernosum larger than the other. When the curve is so severe that it prohibits penetration, it is recommendable to correct it with surgery.
Approximately 0.3 to 0.8 percent of male births the urinary opening, or the urinary meatus, is found on a back part further away in respect to the shaft. This condition is known as hypospadias. This in itself is not a significant problem, and surgery is only recommended only it is easer to deposit semen into the vagina, or if it is easier to urinate. There are many severities of hypospadias, varying with conditions of the urinary meatus scarcely below the head of the penis to the base of the scrota.
Another unusual anatomical condition includes the absence of testicles. Normally in a man the testosterone hormone should circulate normally, and one or both testicles should be present. When the testicles are not seen in the scrota, it may be “undecided", or inside the interior of the abdomen. It’s difficult to find these situations since that they generally correct themselves little after birth.
