Veins of the Penis Dorsal Superficial

Dorsal superficial penile veins: anatomical overview and function

The veins of the penis are an important aspect of its anatomy and play a significant role in maintaining normal blood circulation and erection. Among them, the dorsal superficial veins of the penis, also known as v., deserve special attention. dorsales penis superficiales or PNA (genital neuroarterial veins).

Anatomically, the dorsal superficial penile veins are located on the upper (dorsal) surface of the penis. They run along its length and are venous structures that drain blood from the top of the penis. These veins are usually visible through the skin and may be visually visible during an erection or under certain other conditions.

The function of the dorsal superficial penile veins is to drain blood from the erect penis. During sexual arousal and erection, arterial blood flow in the penis increases, which leads to the filling of the cavernous bodies of the penis with blood. At the same time, a narrowing of the venous vessels occurs, limiting the outflow of blood from the penis. The dorsal superficial veins of the penis, together with other veins of the penis, play an important role in this process, ensuring effective retention of blood in the cavernous bodies of the penis and maintaining an erection.

Certain diseases or pathological conditions may cause dysfunction of the penile veins, which can lead to problems with erection or circulation. However, in most cases, regular physical activity, a healthy lifestyle and adherence to the recommendations of doctors for the care of the penis will help maintain normal penile vein function and overall health of the reproductive system.

In conclusion, the penile veins dorsal superficial, or PNA, are important structures responsible for draining blood from the top of the penis. They play a role in maintaining an effective erection and normal blood circulation in the penis. Understanding the anatomy and function of these veins helps to better understand the mechanisms of erection and possible problems associated with sexual function.

Veins of the penis, dorsal superficial (v. dorsales penisa superficiales, PNA)

The veins of the penis are paired venous canals that flow into the dorsal vein of the penis. Veins are superficial and deep. The superficial dorsal vein penetrates into the thickness of the penis without further branching, the median vein penetrates deeper and is divided into two trunks, the external and internal terminal arteries. The internal terminal artery, in turn, branches and supplies the skin of the shaft of the penis, the labio-genital frenulum. Outer end
