The Penis Has No Muscles But Moves Due To Blood Pressure And Surrounding Muscle Contractions.
The penis is an important part of male anatomy that plays a vital role in sexual intercourse. It is an organ located between the testicles and the rectum that is responsible for producing semen during ejaculation. While it may seem like a simple body part, there are many misconceptions about how it works. One such misconception is that the penis has no muscles, but this is untrue. In fact, the penis moves due to blood pressure and surrounding muscle contractions.
The penis consists of three main parts: the shaft, the glans (head), and the corpus cavernosum (two chambers that fill with blood during erection). The corpus cavernosum is made up of spongy tissue that fills with blood when aroused, causing the penis to become erect. This process is known as erection or penile rigidity. Erection occurs because the penis contains a network of blood vessels called sinusoids which expand to allow more blood flow into the corpus cavernosum. When these sinusoids expand, they compress the veins inside the penis, preventing blood from leaving the corpus cavernosum. As a result, more blood rushes into the penis, causing it to become engorged and erect.
However, the penis does not have any muscles that can directly control its movement. Instead, it relies on blood pressure and surrounding muscle contractions to move. During sexual activity, the brain sends signals to the nervous system which then triggers the release of nitric oxide in the penis. Nitric oxide causes the smooth muscle cells lining the walls of the sinusoids to relax, allowing more blood to flow into them. At the same time, the pelvic floor muscles contract and push blood out of the corpora cavernosa, creating an empty space for more blood to enter. This process repeats itself until the desired level of erection is achieved.
Once the penis is fully erect, it is maintained by muscular contractions around the urethra at the base of the penis. These contractions help keep blood trapped within the corpus cavernosum and maintain the erection. Additionally, small muscles located near the head of the penis can also contribute to movement during intercourse.
In conclusion, despite what many people believe, the penis has no direct musculature that controls its movements. Instead, it relies on blood pressure and surrounding muscle contractions to move. Understanding how this process works is important for men who want to improve their sexual performance or address any issues they may be having with erectile dysfunction.
