Penis Anatomy Basics

The two primary functions of penises are to pee and engage in sex. For penises to engage in these two activities, they must either be flaccid or erect or somewhere in between. Penises come in varying shapes, colours, angle, and skin types. They also have different sensitive areas. Nevertheless, the penis anatomy is typically the same for all penises.

Having the knowledge of how the penis function offers helpful insights into matters sex as well as your body. This article is for someone who is learning about penis functioning for the first time, or someone who wants to know more about it.

First and foremost, let us look at the various parts of a cock. Typically, a penis has three major parts namely;

  1. The root which is connected to the abdominal wall as well as the pelvic wall
  2. The mid portion of the penis( we will look at this part more deeply later on)
  3. The penis glans

The penis body is made up of three cylinders like spaces comprised of soft tissue. For an erection to happen, the two spaces must be filled with blood. Two larger spaces of the soft tissue are known as corpora cavernosa, located on opposite sides of the penis and also responsible for causing penis bulk. The third area is called corpus spongiosum. It is the soft tissue surrounding the urethra and consequently, forms the urinary canal.

As far as penis glans is concerned, there is nothing complicated about it. It is simply the penis head or the cone-shaped end of your manhood. It actually forms the end of the third large space (corpus spongiosum). You must already have heard or read the term corona- if you have studied the penis anatomy before. The corona is the small ridge separating the penis glans from the penis shaft.

That being said, how does erection take place? Why does it happen in the first place? Better still, how does the erection subside?

Well, contrary to common belief, the male member doesn’t have any bones. As stated earlier in this article, the whole thing is about the cylinder like spaces being filled with blood and consequently causing the penis to become large and rigid. Apart from the corpora cavernosa being filled with blood, it must remain there for a given period for a man to maintain the erection long enough.

Let’s go to the basics. It is important that we get this right today. Generally, the brain coordinates everything that we humans feel. Apparently, when a man is sexually aroused, nitric oxide in the penis is released which is responsible for encouraging the flow of blood to the corpus cavernosal arteries. The blood is then trapped inside the soft tissue making the male member to harden. Surprisingly, the third cylinder like space, corpus spongiosum responds in the same way. However, it does become rigid like the other two. The urethra is located here and it is the canal through which a man ejaculates.

How does the erection subside? It happens when the blood in the soft tissues is let out through the dorsal vein. Men who have erectile dysfunction either have a problem with blood flow to the penis, or even nitric oxide. Worse still, it could be that the dorsal veins usually let out the blood from the penis, way too soon.

To this end, I believe you have learnt the very basic details of the anatomy of the penis.
