Adductor brevis muscle (3D)

The video tutorial covers the anatomy and functions of the adductor brevis muscle, located in the medial thigh. It explains the muscle's innervation by the obturator nerve and its attachments to the pubic bone and femur. The primary function of the adductor brevis is thigh adduction, with additional roles in flexion and lateral rotation at the hip joint. The tutorial includes practical examples of these movements and discusses the muscle's involvement in activities like running and kicking. The video concludes with a summary and suggests further reading on the muscle's ancillary functions.
