Lateral plantar muscles of the foot (3D)

The video tutorial explores the anatomy and functions of the lateral plantar muscles of the foot, focusing on the abductor digiti minimi and flexor digiti minimi brevis. It covers their anatomical features, origins, insertions, and nerve supply, as well as their primary functions, including flexion and abduction of the little toe and support of the foot's lateral longitudinal arch. The tutorial concludes with a review of the key points discussed.
