What muscles might be MOST active during this movement? • • • • A. Intertransversii B. Semispinalis C. Multifidi D. Interspinalis Ligaments/Cartilage Ligament Motion Restrictions • Flexion • Posterior Longitudinal Ligament, Inter/Supraspinous Ligaments, Costotransverse Ligaments, Ligamentum Flavum, Nuchal Ligament • Extension • Anterior Longitudinal Ligament • Rotation • Intertransverse Ligaments, Costotransverse Ligaments • Lateral Flexion (Sidebend) • Intertransverse Ligaments, Costotransverse Ligaments, Neurovascular Structures Nerve Roots and Branches Moore et al., (2023)
