Penis Anatomy Basics: Basic Health Facts that All Men Should Know
- All about the Flow. The penis is often described as a tube, and in many ways, that's an accurate description. After all, the penis is designed to transmit all sorts of fluids outside of a man's body in a quick and efficient way. However, the penis is also lined with hollow spaces known as the corpus cavernosum and corpus spongiosum. These spaces are vital to a healthy erection, as they can accept the blood that streams to the area during an erection. When they're filled with blood, the area stiffens and rises from the body. When they're empty, the penis is flaccid.
- Vital Chemicals. Blood doesn't enter the groin through mere suggestion and willpower. Instead, it's summoned there by an intricate network of nerve cells, linking with chemicals released by the brain. When a man senses a sexual signal, his brain releases the neurotransmitter noradrenaline. This chemical triggers a series of further chemical reactions in the penis, relaxing muscles and opening blood vessels so that blood can flow into areas that are normally closed off and empty. These reactions are completely involuntary, meaning that there's no higher thought involved, and they can work within the blink of an eye. As soon as a man senses sex is coming, the process is set in motion and his body gets prepared.
- A Delicate Wrapper. All of this blood flow is encased in a wrapper of intensely sensitive skin. This skin isn't remarkably different than the skin that encases the rest of a man's body, but it's typically hairless and is normally protected within a man's clothing for the vast majority of the day. As a result, the skin is likely to be smooth and responsive. It might also be slightly darker than the skin on the rest of a man's body, simply because it has access to more blood.
- The tip of the penis, known as the glans
- The band of tissue that encircles the glans, known as the corona
- The tissue that encircles the penis, known as the foreskin
- The tiny band of skin that connects the foreskin to the shaft of the penis, known as the frenulum
- Staying in Shape. Penis sensitivity levels can be impacted by haphazard handling techniques. Men who use too much force when interacting with their equipment can lay down scar tissue that can impede sensations of touch. Similarly, rough clothing can cause wee scratches and scrapes that can erode a man's ability to feel almost anything. Using care in handling, and ensuring that penile tissues remain hydrated and moist can be key to keeping everything firing properly.
