: Emerging from the femoral artery, these (divided into superficial and deep) supply the skin of the lower abdomen, scrotum, or labia majora. Physiological Significance
The artery is a landmark during the administration of a pudendal nerve block , a localized anesthesia used during labor. arteria pudenda
: A branch of the internal iliac artery, it follows a complex, "winding" path. It exits the pelvis through the greater sciatic foramen, hooks around the sacrospinous ligament, and re-enters via the lesser sciatic foramen. It then travels within Alcock’s canal (pudendal canal). Its branches—the inferior rectal, perineal, and dorsal arteries of the penis or clitoris—are essential for autonomic and somatic functions. : Emerging from the femoral artery, these (divided
The artery’s most notable role is in the . In males, the deep artery of the penis (a terminal branch) provides the blood flow required for erectile tissue engorgement. In both sexes, it ensures the viability of the pelvic diaphragm and the external sphincters, which maintain urinary and fecal continence. Clinical Implications It exits the pelvis through the greater sciatic
Understanding the pudendal artery is vital for several medical fields:
During pelvic reconstructions or prostatectomies, surgeons must avoid damaging these vessels to prevent hemorrhage or post-operative erectile dysfunction.
