Anatomy & Physiology: Muscles—Longus Colli.

Structure.

  • Superior Oblique
    • Origin: transverse process of C3-C5.
    • Insertion: anterior arch of C1.
  • Inferior Oblique
    • Origin: anterior bodies of T1-T3.
    • Insertion: transverse processes of C5-C6.
  • Vertical
    • Origin: anterior bodies of C5-T3.
    • Insertion: anterior bodies C2-C4.

Function.

  • Concentric action: neck flexion, lateral flexion, contralateral rotation.
  • Reverse mover action: flexion, lateral flexion, and ipsilateral rotation of neck and upper back.
  • Eccentric action: controls/restrains/slows extension and contralateral later flexion of neck; ipsilateral rotation of neck; contralateral rotation of neck and upper back.
  • Isometric action: stabilization of cervical and upper thoracic spine.
  • Innervation: cervical spinal nerves.
  • Arterial supply: inferior thyroid artery, vertebral artery, ascending pharyngeal artery.

Clinical Significance.
