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
Ilicostalis Thoracis
Extension, Lateral flexion T spine
Ilicostalis Cervicis
Extension, lateral flexion, rotation of lower C spine
Longissimus Thoracis
Lateral flexion T spine & ribs (L spine inadvertanbtly); Bilaterally act in extension of T& L spine, hold T&L spine erect (increases L lordosis); lateral movement of pelvis
Longissimus Cervicis
lateral flexion of neck;
bilaterally extend neck
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

Extension, rotation, & lateral flexion of upper T and 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 head
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
Serratus posterior inferior
draws lower 4 ribs down and back; forced inspiration
Longus Colli
flexion & extension of neck; rotation to the contralateral side
Longus Capitis
flex the head
Rectus Capitis Anterior
flex the head
Rectus Capitis Lateralis
laterally flex the head to the ipsilateral side
