The Subtalar Joints and Ligament Diagram

Subtalar joint (talocalcaneal) allows inversion/eversion; ligaments: interosseous talocalcaneal (strongest, in sinus tarsi), medial/lateral talocalcaneal, cervical (stabilizes). It works with transverse tarsal joint for foot flexibility.

Course of the Long Thoracic Nerve Diagram

The long thoracic nerve (C5-C7) descends superficially on serratus anterior, supplying it for scapular protraction/rotation. Injury causes winged scapula and difficulty raising arm overhead.
