Anatomy scholars agree that the pectineus muscle adducts and flexes the hip joint. While some scholars have reported that the pectineus muscle acts as a lateral rotator, others have reported that this muscle acts a medial rotator. This problem is further complicated because a group of scholars does not specify the pectineus muscle's role in hip rotation. The role of the pectineus muscle as a hip rotator, therefore, is not clear to the learner. In this article, the authors discuss the inconsistencies on information about pectineus. As such, it is the responsibility of the instructor to appropriately guide the students through application activities to facilitate student learning and understanding. (Contains 1 table.)
