Description
The fascia covering the medial surface of the obturator internus muscle thickens to form an arch-shaped tendon that attaches from the deep surface of the pubic bone to the ischial spine (Standring, 2016). As the name suggests, this tendinous arch serves as the lateral attachment point for a portion of the levator ani muscles.
