Adduktoren des Hüftgelenks

The video tutorial provides an in-depth look at the adductor muscle group located in the thigh, focusing on their anatomy, innervation, and functions. It covers the six muscles in the group: pectineus, adductor magnus, adductor longus, adductor brevis, adductor minimus, and gracilis. The tutorial explains the role of these muscles in movements such as adduction, rotation, and stabilization of the hip joint, as well as their importance in activities like walking and ice skating. The video also highlights the nerve supply to these muscles and their anatomical connections.
