Some authors consider the artery to be called the penile artery from here on, giving rise to: Bulbar artery supplying the bulb of the urethra, posterior corpus cavernosum, and bulbourethral glands (with the normal capillary blush seen within the bulbar spongiosa), Urethral (spongiosal) artery supplying the corpora spongiosa and providing anastomoses with the dorsal artery of the penis at the glans penis, The deep artery of the penis (cavernosal artery), which divides into helicine arteries that enter the lacunar spaces almost at right angles from the cavernosal artery. After pain relief, this treatment usually begins with a combination of draining blood from the penis and using medications. Ischemic or "low-flow" priapism occurs when blood disorders (such as sickle cell anemia or leukemia), prescription medication, or substance use cause the veins in the penis to constrict and keep blood from exiting the erection chambers (corpora cavernosa).
