What Controls the Erection?

Indeed, some say that the biggest sexual organ is in our heads. It is the brain "in charge" all forms of human sexual sphere: it creates an emotional mood, the need for sexual intercourse, attraction to the opposite sex and provides a reaction, realizing this attraction. In the language of science attraction to the opposite sex called "libido." Against the background of libido erotic pictures in combination with stimulation of the areas causing sexual arousal center in the brain. As a result, nerve impulses are rushing from the center to the various organs and cause heart "flutter", and breathing - more frequent. Blood pressure rises. Under the "leadership" centers of the spinal cord penis fills with blood, repeatedly (4-10 times) increases and strains. So there is an erection. Emotional arousal and activation of the glans penis lead to a reduction in seminal vesicles and release of sperm - ejaculation and orgasm. Violation of any of the coordinated work of these links may cause sexual disorders, primarily the loss of the capacity for erection. From ancient times was the search for means that would help the man. He drank a love potion, or better yet unobtrusive swallowed a pill - and please, appeared before a woman in full force and readiness. Such tools called "afrodiziakum" on behalf of Aphrodite, the Greek goddess of sensual love. Despite the centuries-old quest, the vast majority of these funds were either tonic like ginseng and vitamins, or exciting, like coffee and chocolate, or just mascots, acting purely psychological. The only effective means was the bark of the African yohimbe tree. Why is it so hard to influence the behavior of the penis? After all, people are usually well managed by his body: even with his eyes closed and in weightlessness his hands and feet in full are subject to the will. But the thing is that we are able to command only those muscles which are attached to bones. But there are other muscles that are not subject to us. They are located in the walls of internal organs and blood vessels. The penis is under the control of these muscles, and therefore almost independent of the will of the owner. Nevertheless, its behavior is determined by nerve impulses. Nervous system of regulation reminds telegraphy. At the command post there is an "order" in the form of electrical signals that run through the wires - the nerves. At the end of the wire sits "telegraph," sending the pulses in the order, which serve the public. These orders and there are those substances that cause the muscle is reduced, then relax.
Inside the penis are two so-called cavernous body. Along the walls of the "caves" are the muscles through which they can change their volume. In the usual, "sluggish" state of the muscles of cavernous bodies and muscles of small arteries of the penis in a state of weak reductions - tone. They constantly circulates a small amount of blood, but to give the elasticity of the penis is not enough. The situation is completely changed when sexual excitement. By genitals received powerful impulses that cause relaxation of muscle fibers in the walls of arteries and corpus cavernosum penis. As a result, the penis and erectile tissues fill with arterial blood, increasing in size - there is an erection. When sexual arousal decreases, the muscles in the cavernous bodies are reduced and squeezed out their blood like water from a sponge - there comes an end to an erection. Substance which gives the order to relax the muscles, called acetylcholine. It is rapidly destroyed special enzyme. When rats were injected substances, suspending the operation of this enzyme, they copulate for hours. However, these substances act indiscriminately. American scientists have proposed another solution to this problem. In 1998 he was awarded the Nobel Prize in Medicine for his discovery of special chemical link between acetylcholine and muscle. This nitric oxide, which ensures the formation of substances that lead to relaxation of the muscles of the corpora cavernosa and the erection. Now, pharmacologists were able to manage this process.
