  • Lateral Lines (LL)

          Lateral flexion is the movement around the vertical axis and is delineated by the Lateral Lines. It has to work with the spine both in extension and flexion so it has 2 courses at the neck and lumbar area depending on the horizontal position of the spine.

  • The Lateral Lines are Bilateral (run along both sides)
    • Each line follows the Peroneus tertius m. from the hock proximally to the lateral collateral ligament of the Stifle...
    • ... into the Tensor fascia lata m. and the Superficial gluteal m.,
    • ... to the Tuber Coxa where it changes direction from vertical to horizontal.
    • From here the fibers form a criss-cross pattern as the line passes through the aponeurosis and fascial tissue of the External and Internal Oblique Abdominal mm., to the Costal arch & to the Internal and External intercostal mm.
    • Part of the Lateral Line becomes integrated into the Cutaneus trunci mm., Cutaneus  omobrachialis mm., Brachiocephalicus mm., Mastoid process and Temporal bone.
