(the fascia of perineum is a deep fascia that covers the superficial perineal muscles individually). its superior border is the perineal membrane (inferior fascia of the urogenital diaphragm). contents muscles ischiocavernosus muscle bulbospongiosus muscle superficial transverse perineal muscle erectile bodies corpus cavernosum (of penis and of clitoris) corpus spongiosum (of penis) vessels posterior scrotal arteries (males)/labial arteries (females) artery to bulb (males)/vestibule (females) urethral artery nerves posterior scrotal nerves (males)/posterior labial nerves(females) other crura of penis (males) / crura of clitoris (females) bulb of penis (males) / bulb of vestibule (females) bartholin's glands (female) spongy urethra contained in the corpus spongiosum additional images median sagittal section of male pelvis, showing arrangement of fasciæ. muscles of female perineum.
