Deep artery of penis
The artery to the corpus cavernosum is another term used to describe the deep artery of penis. The internal pudendal, which is the artery or vein that provides blood to the external genitalia and branches off of the internal iliac artery. The internal iliac artery is defined as the pelvis' main artery. A terminal branch of the pudendal comes up from a vessel while situating itself between the urogenital diaphragm's two fasciae. The urogenital diaphragm has also been referred to as the triangular ligament and is defined as the pelvis' layer that separates the upper pelvis from the deep perineal sac. The deep perineal sac is the pouch or space that is partially enclosed by the perineum and is situated higher than the perineal membrane. The deep artery of penis enters the crus penis after piercing through the inferior fascia. It then runs down the corpus cavernosum penis' center and then branches off. The corpus cavernosum of the penis is one of the pairs of tissues that resemble sponge material and are located in regions of erectile tissue, where most of the blood is contained during an erection.
