List the muscles of the neck and back that move the vertebral column | splenius, erector spinae, longissimus, spinalis |
List splenius muscles | splenius capitis, splenius cervicis |
splenius capitus origin | ligamentrum muscle and spinous process of c7-t4 |
splenius capitus insertion | occipital bone and mastoid process of temporal bone |
splenius capitis action | acting together (bilaterally, extend head and extend vert column;acting singly unilaterally , laterally flex and or rotate head t same side as contracting muscle |
splenius capitis innervation | middle cervical spinal nerves |
splenius cervicis origin | spinous process of t3-t6 |
splenius cervicis insertion | transverse process of c1-c2 or c1-c4 |
splenius cervicis action | acting together, extend head; acting singly lat flex and or rotate head to same size as contracting muscle |
List erector spinae | iliocostalisis cervicis, iliocostalis thoracis, iliocostalis lumborum, |
iliocostalis cervicis origin | ribs 1-6 |
iliocostalilisis insertion | trasverse process of c4-c6 |
iliocostalisis action | acting together, muscles of each region extend and maintain erect posture of vert column of their respective regions, acting singly, lat flex vert column of their respective regions to same side as contracting muscle |
iliocostalisis thoracis origin | ribs 7-12 |
iliocostalisis thoracis insertion | ribs 1-6 |
iliocostalisis thoracis action | same as cervicis |

longissimus capitis insertion | mastoid process of temporal bone |
longissimus capitis action | acting together, both longisismis capitis muscles extend head and extend vert column; acting singly rotate head to same side as contracting muscle |
llongissimus capitis innervation | middle and inferior cervical spinal nerves |
longissimus cervicis origin | transverse process of t4-t5 |
longissimus cervicis insertion | transverse processes of c2-c6 |
longissimus cervicis action | acting together , longissimus cervicis and both longissimus thoracis musckes extend vert column of their respective regions. Acting singly, lat flex vert column of their respective regions |
