Spine and Thorax Flashcards
Erector Spinae Group Action Unilaterally
Laterally flex vertebral column to the same side
Erector Spinae Groups Action Bilaterally
Extend the vertebral column
Erector Spinae Group Origin
Common tendon (thoracolumbar fascia) that attaches to the posterior surface of sacrum, iliac crest, spinous processes of the lumbar and las two thoracic vertebrae.
Erector Spinae Group Insertion
Various attachments at the posterior ribs, spinous and transverse processes of thoracic and cervical vertebrae and mastoid process of temporal bone
Spinalis Origin
Spinous processes of the upper lumbar and lower thoracic vertebrae (thoracis). Ligamentum nuchae, spinous process of C-7 (cervicis)
Spinalis Insertion
Spinous processes of upper thoracic (thoracis)
Spinous processes of cervicals, except C-1 (cervicis)
Longissimus Origin
Common tendon (thoracis). Transverse processes of upper five thoracic vertebrae (cervicis and capitis)
Longissimus Insertion
Lower nine ribs and transverse processes of thoracic vertebrae (thoracis). Transverse processes of cervical vertebrae (cervicis). Mastoid processes of temporal bone (capitis)
Ilicostalis Origin
Common tendon (lumborum). Posterior surface of ribs 1-12 (thoracis and cervicis)
Ilicostalis Insertion
Transverse processes of lumbar vertebrae 1-3 and posterior surface of ribs 6-12 (lumborum). Posterior surface of ribs 1-6 (thoracis). Transverse processes of lower cervicals (cervicis)
Multifidi and Rotatores Action Unilaterally
Rotate the vertebral column to the opposite side
Multifidi and Rotatores Action Bilaterally
Extend the vertebral column
Multifidi Origin
Sacrum and transverse processes of lumbar through cervical vertebrae
Rotatores Origin
Transverse processes of lumbar through cervical vertebrae
Multifidi and Rotatores Insertion
Spinous processes of lumbar vertebrae through second cervical vertebrae. (Multifidi span two to four vertebrae) (Rotatores span one to two vertebrae)
