The structure of the penis men

From the course of anatomy it is known that the penis(penis) is one of the organs of the reproductive and genitourinary system, and serves to excrete seminal fluid and urine, as well as coition. If we consider the structure of the penis, we must say that it has a back part - the root, due to which it is attached to the bones of the womb, the middle part - the trunk, consisting of cavernous two bodies filled with blood fluid during an erection, due to which the penis becomes hard and increases in size. It also has a front part, somewhat thickened - the head, while the crown does not have a penis.

So, to begin to study the structure of the penis of a man we will be from its middle part - the trunk (body).

The trunk consists of a spongy and two cavernous bodies,cavities of which consist of cavernous bodies, they are filled with blood during sexual arousal. At the same time, the penis changes its size dramatically (it increases three-fold), becomes firm and elastic, which means that an erection occurs. Next, the inflow-outflow is regulated until the ejaculation, after which the erection ends, and the blood, respectively, recedes.

Cavernous bodies are represented in the form of two elongated bodies of cylindrical shape with slightly pointed edges that are attached to the pelvic bones of the pelvis, forming the root of the penis.

The structure of the penis of men is providedso that the urethra passes inside the spongy body of the penis (between the cavernous bodies), the ducts of the gland open up to it, which secretively secrete the secret at the onset of sexual arousal. This secret helps to moisten the channel.

The head of the penis is covered with reddish skinwith a lot of glands that produce a syrup, and a lot of nerve endings. It always remains soft, representing the so-called buffer between the solid cavernous bodies and the tissues of the woman's vagina.

The head of the penis is covered by the foreskin (shecan be of different magnitude), the removal of which at an early age makes it possible to avoid the appearance of various inflammatory processes that can cause such diseases of the penis as cancer.

It should be said that the foreskin consists ofexternal (indistinguishable from the skin) and inner (soft) leaves. Between the inner leaf and the head of the penis is a cavity, which opens in front of the hole. The structure of the penis of each member of the stronger sex is provided so that the foreskin can easily move back, while the head is exposed and enters the preputial space, highlighting a special secret that helps to improve this displacement.

On the underside of the penis, the foreskin is connected to the head by a so-called bridle, that is, a fold of the skin, inside which the nerves and blood vessels pass.

Thus, the sex organs in men are divided intointernal and external. Internal organs provide conception, as a result of which a new life arises, whereas the external ones take a direct part in sexual intercourse.
