Splenius Capitis
Laterally flex head & rotate face to side; bilaterally extend
head
Splenius Cervicis
Laterally flex & rotate neck; bilaterally extend neck
Iliocostalis Lumborum
Extension, lateral flexion, rotation of L spine; lateral movement of pelvis
Iliocostalis Thoracis
Extension, lateral flexion T spine
Iliocostalis Cervicis
Extension, lateral flexion, rotation lower C spine
Longissimus Thoracis
Lateral flexion T spine & ribs (L spine inadvertenly); bilaterally act in extension of T & L spine, hold T & L spine erect (increases L lordosis); lateral movement of pelvis
Longissimus Capitis
rotate & laterally flex head; bilaterally extend head
Spinalis Thoracis
extend T spine
Spinalis Cervicis
lateral flexion & rotation of C spine; bilaterally extend neck
Spinalis Capitis
lateral flexion & rotation of head; bilaterally extend head
Semispinalis Thoracis
Extension, rotation, & lateral flexion of upper T & lower C spine; bilaterally extend T spine
Semispinalis Cervicis
Extension, rotation, & lateral flexion of C spine; bilaterally extend neck
Semispinalis Capitis
turns face to side; bilaterally extends head (neck inadvertently)
Rectus Capitis Posterior Major
turns face to side; bilaterally extends head
Rectus Capitis Posterior Minor
Extends Minor
Obliquus Capitis Superior
Lateral flexion of head; bilaterally extends head
Obliquus Capitis Inferior
turns face to side
Quadratus Lumborum
steadies origin of diaphragm; when pelvis is fixed, it will laterally flex the L spine; bilaterally extends the L spine; stabilizes & depresses the 12th rib
Serratus Posterior Superior
Elevate upper 5 ribs in inspiration
Longus Colli
Flexion & extension of neck; rotation to the contralateral side
Longus Capitis
Rectus Capitis Anterior
Flex the head
