What is the pelvis


bony sturcture conencting teh lower extremities tot eh rest of the body

area connecting teh abdomial cavity to the perineum


What is in teh pelvic cavity?


pelvic viscera

parts of urinary and gi systems

reproductive system parts


How do the false and true pelvis differ?

Pelvic brim sperates them

FALSE PELVIS: above pelvic brim, inferior border: pelvic inlit

TRUE PELVIS: below pelvic brim inferior pelvic appature closed by pelvic diagphragm muscles.  has pelvic viscera
