Gracilis muscle (3D)

The tutorial explores the functions of the gracilis muscle, a part of the medial compartment of the thigh. It details the anatomy, nerve supply, and the muscle's role in movements at the hip and knee joints. The gracilis is involved in thigh flexion, adduction, knee flexion, and internal rotation. The video uses a model to demonstrate these movements, emphasizing the muscle's contribution to everyday activities like climbing stairs and crossing legs.
