OINA for test 3 Flashcards

1
Q

OINA for levator ani

A
  • Origin: body of pubis, obturator fascia, ischial spine
  • Inserts: coccyx
  • Innervation: nerve to the levator ani (S3, S4)
  • Action: Forms muscular sling to support abdominopelvic viscera, holds pelvic viscera in position, assist with abdominoplevic cavity compression, utilized with coughing, sneezing, vomiting, etc.
