Flashcards in OINA for test 3 Deck (26):
1

OINA for levator ani

- 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.

2

OINA for the coccygeus

- Origin: ischial spine

- Insertion: inferior end of the sacrum & coccyx

- Innervation: branches of S4 and S5 spinal nerves

- Action: Supports pelvic viscera, forms posterior part of diaphragm
