Gluteus medius muscle (3D)

This tutorial explores the gluteus medius muscle, highlighting its anatomy, innervation, and key functions. The gluteus medius is crucial for maintaining posture and balance while walking. It acts as a strong abductor of the thigh, assists in internal rotation, and stabilizes the pelvis during movement. The video also discusses the Trendelenburg gait, a condition resulting from gluteus medius dysfunction. The tutorial concludes with a recap of the muscle's functions and encourages viewers to explore related anatomy videos.
