The cavernous nerves travel from the underside of the
penis
to the prostate. They regulate blood flow within the penis. In the flaccid state, relatively little blood flows in through the arteries and there is free outflow via the small veins exiting the spongy tissue just under the thick tunica (membrane surrounding the spongy tissue). During erection, the smooth muscle in the penis relaxes while the arteries widen to bring in more blood.
This expands the three cylinders of erectile tissue in the penis, thus lengthening and enlarging the penis. The expansion of these cylinders compresses the small veins, reducing the outflow of blood.
Toggle accordion item the cylinders of the implant, which are inserted into the erectile chamber of penis act as a reservoir that hold the saline next to the bladder. When the patient pumps the device using the button that has been inserted into the scrotum, the cylinders will fill up with the saline from the reservoir, giving the patient a normal erection . To return to the flaccid state, the patient simply presses the button once more and everything returns to normal.
A proper balance of certain chemicals, gases, and other substances is critical for erectile health . Collagen the protein collagen is the major component in structural tissue in the body, including in the penis. However, excessive amounts of collagen can form scar tissue, which can impair erectile function. Oxygen oxygen-rich blood is one of the most important components for erectile health. Oxygen levels vary widely from very low levels in the flaccid state to very high levels in the erect state. During sleep, a man can normally have 3 to 5 erections per night, bringing oxygen-rich blood to the penis. The primary cause of oxygen deprivation is ischemia, or the blockage of blood vessels.
Α-adrenergically mediated contraction of cavernosal and vascular smooth muscle limits blood flow to the penis and maintain the usual flaccid state. An erection occurs when erotic stimuli, received via any of the five senses and processed in the hypothalamus, results in inhibition of sympathetic tone and release of nitric oxide (no) from nonadrenergic, noncholinergic (nanc) nerves and endothelial cells of the arterioles in the penis ( 5 ). No activates guanyl cyclase, thereby generating cyclic guanosine monophosphate (cgmp). Cgmp decreases calcium uptake into vascular and cavernosal smooth muscle and induces relaxation. Smooth muscle relaxation permits engorgement of cavernosal sinusoids with blood and the development of an erection.
