  • Superficial Dorsal and Superficial Ventral Lines

          The Superficial Ventral Lines (SVL) and the Superficial Dorsal Lines (SDL) both connect at the head where the fibers of the Temporal muscle merge with the Masseter muscle, connecting the Temporomandibular joint (TMJ) through the length of the body.
           The SVL and SDL also connect at the coffin bone (P3) of the hind limb where the extensor and flexor tendons attach (respectively), as well as through the branches of the Suspensory ligament as it merges with the extensor tendons.

  •       Working together, the Superficial Ventral and Dorsal Lines coordinate flexion of the spine and hips and extension of the hind legs. If the SVL is hypertonic and the spine hyper-flexed, the hind limbs will be standing under.

  • The SDL influences the following musculoskeletal parts:
    • Suspensory ligament of hind limbs (area of origin)
    • Flexor tendons
    • Gastrocnemius m.
    • Biceps femoris m.
    • Semitendinosus m.
    • Sacrotuberous ligament
    • Erector spinae muscle group (Spinalis m., Longissimus dorsi m., Iliocostalis m.)
    • Longissimus cervicus m.
    • Longissimus capitis m.
    • Semispinalis capitis m.
    • Ending at the crest of the Occiput & Temporal myofascia
  • The SVL influences the following musculoskeletal parts:
    • Extensor tendons, hind limb attachment @ P3 (origin) - Long & Lateral digital extensor mm.
    • Peroneus tertius m.
    • Patella & assoc. ligaments
    • Quadricep femoris muscle group (Vastus lateralis m., V. medius m., V. intermedius m., Rectus femoris m.)
    • Coxa-femoral joint
    • Rectus abdominalis m.
    • Rectus thoracis m.
    • Sternum / manubrium of Sternum
    • Sternomandibularis m.
    • Mandible & ends in fascia of the Masseter m.
