Erector Spinae Group (in general)
Action: Unilaterally - Laterally flex vertebral column to same side.
Bilaterally: Extend the vertebral column.

Origin: Common tendon (thoracolumbar aponeurosis) that attaches to the posterior surface of sacrum, iliac crest, spinous processes of the lumbar and last two thoracic vertebrae.

Insertion: Various attachments at the posterior ribs, spinous and transverse processes of thoracic and cervical vertebrae, and mastoid process of the temporal bone
Spinalis Thoracis (Erector Spinae Group)
Origin: Spinous processes of the upper lumbar and lower thoracic vertebrae

Insertion: Spinous processes of upper thoracic
Spinalis Cervicis (Erector Spinae Group)
Origin: Ligamentum nuchae, spinous process of C-7.

Insertion: Spinous processes of cervicals, except C-1
Longissimus Thoracis (Erector Spinae Group)
Origin: Common tendon

Insertion: Lower 9 ribs and transverse processes of thoraic vertebrae
Longissimus Cervicis (Erector Spinae Group)
Origin: Transerverse processes of upper 5 thoracic vertebrae

Insertion: Transverse processes of cervical vertebrae
Longissimus Capitis (Erector Spinae Group)
Origin: Transverse processes of upper 5 thoarcic vertebrae.

Insertion: Mastoid process of temportal bone
Iliocostalis Lumborum (Erector Spinae Group)
Origin: Common tendon

Insertion: Transverse processes of lumbar vertebrae 1-3 and posterior surface of ribs 6-12
Iliocostalis Thoracis (Erector Spinae Group)
Origin: Posterior surface of ribs 1-12

Insertion: Posterior surface of ribs 1-6

Multifidi and Rotatores (Transversospinalis Group)
Action: Unilaterally - Rotate the vertebral column to the opposite side.
Bilaterally: Extend the vertebral column

Origin: Multifidi - Sacrum and transverse processes of lumbar through cervical vertebrae
Rotatores: Transverse processes of lumbar through cervical vertebrae.

Insertion: Spinous processes of lumbar vertebrae through second cervical vertebra

(Multifidi spans 2-4 vertebrae, while the rotatores spans 1-4 vertebrae)
Semispinalis Capitis (Transversospinalis Group)
Action: Extend the vertebral column and head

Origin: Transverse processes of thoracic vertebrae, articular processes of lower cervicals
