Course
From their origin, the posterior labial veins enter the superficial pouch, and travel posteriorly, below the perineal membrane to drain into the internal pudendal vein (Netter, 2011). The posterior labial veins may also drain into the perineal vein or vesical venous plexus or the (not modeled) (Dorland, 2011).
