The lateral wall of the ischioanal fossa is formed by the fascia of which muscle?

Explanation:
Ischioanal fossae are wedge-shaped spaces on each side of the anal canal. Their lateral boundary is formed by the fascia that covers the obturator internus muscle as it travels through the pelvis and along the lateral wall. This obturator fascia not only defines the boundary but also contains the pudendal canal, through which the internal pudendal vessels and pudendal nerve run. The other fasciae mentioned belong to different regions or walls and do not form the lateral boundary of the ischioanal fossa.
