Superior: SPs of vertebrae, spanning 2-4 vertebrae superior to superior attachment
Attachments: Rotatores
Inferior: TPs of vertebrae; best developed in thoracic region
Superior: Fibers pass superomedially to attach to junction of lamina and TP or SP of vertebra, spanning 1-2 vertebrae to superior attachment
Attachments: Rectus Abdominus
Inferior: Iliac crest, thoracolumbr fascia, cartilages of ribs 6-12, and inguinal ligament
Superiior: Linea alba with aponeurosis of internal oblique; pubic crest, and pectin pubis

What does ipsilateral mean?
Contralateral?
Axial rotation?
Same side
Opposite side
Side-side around vertebral column
What are one side and two side contractions called?
unilateral and bilateral
What are Extrinsic musles?
The main job is to move the shoulder complex but not the vertebral column
What do Intrinsic muscle do?
Move the back and vert column
They are in 3 layers that are deep to the extrinsic
they are located on both sides of the VC
What does capitus mean?
What does cervisis mean?
Attaches to the skull
Attaches to neck
