Question

Describe the path of the internal pudendal artery:

A) Passes through the greater sciatic foramen to reach the perineum
B) Travels along the lateral pelvic wall to supply the pelvic organs
C) Passes through the lesser sciatic foramen to reach the thigh
D) Runs within the rectus sheath to supply the abdominal muscles

Answer 1

The internal pudendal artery emerges from the internal iliac artery and supplies blood to several pelvic regions, passing through the greater sciatic foramen to reach the perineum.

Step-by-step explanation:

The path of the internal pudendal artery is described as follows: It originates from the internal iliac artery which is a branch from the common iliac arteries. The internal pudendal artery supplies blood to the urinary bladder, walls of the pelvis, external genitalia, and the medial portion of the femoral region. In females, it also provides blood to the uterus and vagina. Specifically, the internal pudendal artery passes through the greater sciatic foramen to reach the perineum. Therefore, the correct path description for the internal pudendal artery is: A) Passes through the greater sciatic foramen to reach the perineum.
