ANATOMY: pelvic Cavity & Reproductive System Flashcards
Structures of pelvic floor
Pubococcygeus
Puborectalis
Iliococcygeus
Attaches from the pubis to midline as far back as the coccyx.
Can be further subdivided into puboprostaticus, pubovaginalis, and puboanalis depending on associated structures.

Maintains the perineal flexure to keep the GI system closed.
Puborectalis
Attaches from the obturator internus muscle fascia to join the paired muscle in the midline.
