Deep ventral line


Pictures of the line

Consists of the following muscles and connective tissues

Additional Functional Muscles Supporting The Deep ventral line

Attaches To The Following Bones

  • Tarsal plantar bones, plantar surface of toes
  • Superior/posterior tibia/fibula
  • Medial femoral epicondyle
  • Linea aspera femoris
  • Trochanter minor femoris
  • Ischial ramus
  • Coccyx
  • Lumbar vertebral bodies and processus transversi
  • Posterior surface of subcostal, cartilages and processus xiphoideus
  • Posterior manubrium
  • Hyoid bone
  • Mandible
  • Processus transversi of cervicals
  • Basilar portion of occiput

Function of line

  • Lifting the inner arch of the body, and therefore important in the body's support
  • Giving support to the lumbar spine from the front
  • Stabilizing the chest while allowing the expansion of the ribs for relaxation of breathing
  • Stabilizing and balancing the neck and head
  • Stabilizing each segment of the legs
  • Overload of the line will result in less bodily stabilization and higher involvement of the other lines to support the body. Thus increasing the load of other muscles and structures and simultaneously increasing the likelihood of causing injuries to these compensated lines

Compensation Patterns Associated With The Line

  • Chronic plantarflexion
  • High and fallen arch patterns of the feet
  • Pronation and supination
  • Genu valgus and varus
  • Anterior pelvic tilt
  • Pelvic floor insufficiency
  • Lumbar malalignment
  • Breathing restriction
  • Flexed or hyperextended cervicals
  • Temperomandibular joint syndrome (TMJ)
  • Swallowing and language difficulties
  • General core collapse

Dysregulation of line

  • Produces overall shortening in the body, encourage collapse in the pelvic and spinal core
  • Eventhough the line is dysregulated, in many cases there may be several years before a obvious injury occurs due to the body's ability to compensate. So a loss of function within the line does not necessarily involve an immediate injury or collapse
