From: Architecture of the Short External Rotator Muscles of the Hip
Scatterplot of fiber length versus PCSA for the selected muscles reported here (open circles) in comparison to the gluteus medius and maximus data collected previously (filled circles) [21]. The combined value for the short external rotators (gemelli and obturators) is displayed as well. QF = quadratus femoris, ObE = obturator externus, ObI = obturator internus, SG = superior gemellus, IG = inferior gemellus, Pi = piriformis, Pe = pectineus
