Muscles of the leg

This video tutorial explores the anatomy of the leg, focusing on the bones and muscles. It covers the anterior, lateral, and posterior compartments, detailing the origin, insertion, function, and innervation of each muscle. The tutorial also discusses clinical notes on foot drop, its causes, and potential treatments.

What are the two crucial movements discussed in the introduction of the tutorial?

• Abduction and Adduction

• Dorsiflexion and Plantar Flexion

• Flexion and Extension
