Our obliques are part of our abdominal muscles. There are Internal and External obliques.
Today let's get to know the Internal!
Muscle Attachment point(s) :
Origin: Lateral 2/3 of the inguinal ligament, the iliac crest and the thoracolumbar fascia (connective tissue deep in the torso)
Insertion: Internal surface of lower three ribs (10-12) and the abdominal aponeurosis
Muscle Action(s) :
-Unilaterally (one side only) : lateral flexion of spine to one side
- also rotates spine to the same side
above: Lateral Flexion to one side. (In this case - to the right !)
aka Ipsi-lateral flexion
aka Side Flexion or 'C spine'
Above: Ispi Lateral Rotation of the spine
aka Lateral rotation to one side
aka "Spinal Twist to left or right"
Check out my video of the 6 movements of the spine for a
closer look at the above mentioned spine movements!
And stay tuned for a blog post that will really break down the 6 movements of the spine in further detail :)
-Bilaterally (both sides -left & right together) : spinal flexion -
which is basically a sit up! Remember Rectus Abdominus ?
