Female Urogenital Triangle

Superficial 1st Layer

  • Superficial transverse perineal (helps stabilize perineal body)
  • Bulbocavernosus (helps with vaginal sphincter and assists in erection of clitoris in women and penis in men - bulbospongiosus)
  • Ischiocavernosus (in women maintains clitoral erection and in men maintains penal erection

2

Female Urogenital Triangle

Deep Layer (2nd Layer)

  • Deep Transverse Perineal (compresses ventral wall and assists with continence
  • Compressor Urethrae (compresses urethra and assists with continence)
  • Sphincter Urethrae (closes urethra lumen and helps support bladder)

3

Pelvic Diaphragm

Deepest Layer (3rd Layer)

  • levator ani
    • Pubococcygeus
    • Iliococcygeus (elevates pelvic floor)
    • Puborectalis (Sphincter vagina & urethra)
    • Pubovaginalis

 

  •     -obturator internus
