License Image The obturator internus arises from the inner surface of the pelvis where it partially covers the obturator foramen. The muscle fibers converge into a tendinous band which lies between the ischial spine and ischial tuberosity, and makes a sharp turn around the ischial bone as it heads towards it’s insertion on the greater […]
License Image The piriformis is a flat triangular shaped muscle that originates inside the pelvis and passes through the sciatic foramen on it’s way to insertion on the greater trochanter of the femur. The superior gemellus lies parallel to the obturator internus tendon, and it’s tendon blends with that of the obturator as it inserts […]
License Image This group of outer hip muscles includes the piriformis, superior gemellus, inferior gemellus, obturator internus and obturator externus. With their insertions on or near the greater trochanter of the femur, these muscles rotate the thigh laterally.
License Image Pelvic Floor Muscles The muscles of the "pelvic floor" or "pelvic diaphragm" are the levator ani, and the coccygeus. The levator ani is divided into two parts: the pubococcygeus and the iliococcygeus. Kegel exercises are designed to strengthen the muscles of the pelvic floor, primarily the pubococcygeus muscle. These exercises are usually done […]
