34

Splenius Capitis- Action

Laterally flex head & rotate face to side; bilaterally extend head

35

Splenius Cervicis- Action

Laterally flex & rotate neck; bilaterally extend neck

36

Iliocostalis Lumborum- Action

Extension, lateral flexion, rotation of L spine; lateral movement of pelvis

37

48

Rectus Capitis Posterior Major- Action

turns face to side; bilaterally extends head

flex the head

58
