Pectineus muscle (3D)

This video tutorial explores the anatomy and functions of the pectineus muscle. It begins with an overview of the muscle's location and structure, highlighting its flat quadrilateral shape and its position from the pelvis to the femur. The tutorial explains the muscle's classification as an adductor of the thigh, its innervation by the femoral nerve, and occasionally by the obturator nerve. The functions of the pectineus muscle are detailed, including its role in thigh adduction, flexion, and potential assistance in internal and external rotation. The video concludes with a summary of these functions.
