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