What is the action of longus colli?
Function. As well as acting with the other cervical flexors to produce neck flexion, Longus Colli has been shown to have a postural function on cervical curvature, counteracting the lordosis increment related to the weight of the head and to the contraction of the posterior cervical muscles.
