splenius capitis actions
laterally flex head & rotate face to side; bilaterally extend head
splenius cervicis actions
laterally flex & rotate neck; bilaterally extend neck
iliocostalis lumborum actions
extension, lateral flexion, rotation of L spine; lateral movement of pelvis
iliocostalis thoracis actions
extension, lateral flexion T spine
iliocostalis cervicis actions
extension, lateral flexion, rotation lower C spine
longissimus thoracis actions
lateral flexion T spine & ribs (Lspine inadvertently); bilaterally act in extension of T & L spine, hold T & L spine erect (increases L lordosis); lateral movement of pelvis
longissimus cervicis actions
lateral flexion of neck; bilaterally extend neck
