Blood can leave the erectile tissue only through a drainage system of veins around the outside wall of the corpus cavernosum. The expanding spongy tissue presses against a surrounding dense tissue (tunica albuginea) constricting these veins, preventing blood from leaving. The penis becomes rigid as a result.
Erectile tissue exists in external genitals such as the corpora cavernosa of the penis and their homologs in the clitoris, also called the corpora cavernosa. [2] During penile or clitoral erection, the corpora cavernosa will become engorged with arterial blood, a process called tumescence. [3]
Penile injury by self-mutilation involves injury to the glans penis by a needle puncture (left) or to the root of the penis by hanging a heavy-duty combination vise that clamped the penis (right). The type of injury from these self-harming behaviors varies from skin laceration to total amputation of the penis.
After vasocongestion, the now-engorged erectile tissue presses against and constricts the veins that carry blood away from the penis. More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at ...
Venous leak is an inability to maintain an erection in the presence of sufficient arterial blood flow through the cavernosal arteries of the penis. [6] The defect lies in the excessive drainage of veins in the cavernosal tissue of the penis, which undermines normal erectile function.
Section of corpus cavernosum penis in a non-distended condition. a. Trabeculae of connective tissue, with many elastic fibers and bundles of plain muscular tissue, some of which are cut across (c). b. Blood sinuses.
Red bumps on the penis that are associated with this condition are caused by HPV. The condition, says Dr. Williams, “is marked by red-brown lesions on the glans or shaft, usually in circumcised men.
The root of the penis begins directly below the bulbourethral glands, or Cowper glands, and consists of three long masses of tissue; the bulb and the crura.The bulb of the penis is an enlarged mass of erectile tissue that is located in the midline of the root and is traversed by the male urethra.
