Document Summary
8th 12th ribs (inferior borders, near angles) Lateral 1/3 nuchal line (occipital bone); mastoid process (temporal bone) 6th 12th ribs; thoracolumbar fascia (posterior layer); upper lumbar vertebrae (transverse process) T1-t3 (transverse processes); c4-c7 (transverse and articular processes) Sacrum; iliac crest; lumbar vertebrae (spinous processes); lower thoracic vertebrae (transverse process) 2nd-12th ribs; thoracic and lumbar vertebrae (transverse processes) Spinal nerve c8 l1 (posterior rami, lateral branches) Unilateral: flexes and rotates head to same side. Unilateral: bends cervical and thoracic spine to same side. T1-t12 (between transverse and spinous processes of adjacent vertebrae) T1-t12 (between transverse and spinous processes, skipping one vertebrae) Sacrum, ilium, mammillary processes of l1-l5, transverse and articular processes of t1-t4, c4-c7. Superomedially to spinous processes, skipping two to four vertebrae. Occipital bone between superior and inferior nuchal line. Unilateral: flexes spine to same side, rotates it to opposite side. Bilateral: extends thoracic and cervical spine and head (stabilizes craniovertebral joints)
