prevertebral muscles


Definition: muscles deep to the prevertebral fascia on the anterior surface of the cervical and superior three thoracic vertebrae, symmetrically placed on each side of the median plane, including the longus colli, longus capitis, rectus capitis anterior, and rectus capitis lateralis muscles; some authorities define the group as medial to the plane of the cervicobrachial plexus, and thus also include the anterior scalene muscle. They are flexors of the head and neck, innervated by anterior rami of cervical spinal nerves.
