Adductor magnus muscle (3D)

The video tutorial covers the functions of the adductor Magnus muscle, a composite muscle with multiple parts and innervation sources. It explains the structure, location, and variability of the adductor minimus muscle. The tutorial details the innervation from the obturator and sciatic nerves, and the muscle's proximal and distal attachments. It describes the muscle's actions, including adduction, flexion, and extension of the thigh, and touches on its role in lateral rotation. The video concludes with a summary of the muscle's functions and encourages further research.
