The Longus colli muscle is amuscle of thehuman body .The Longus colli is situated on the anterior surface of the
vertebral column , between the atlas and the thirdthoracic vertebra .It is broad in the middle, narrow and pointed at either end, and consists of three portions, a superior oblique, an inferior oblique, and a vertical.
* The "superior oblique portion" arises from the
anterior tubercles of the transverse processes of the third, fourth, and fifthcervical vertebræ and, ascending obliquely with a medial inclination, is inserted by a narrow tendon into the tubercle on theanterior arch of the atlas .* The "inferior oblique portion", the smallest part of the muscle, arises from the front of the bodies of the first two or three
thoracic vertebræ ; and, ascending obliquely in a lateral direction, is inserted into the anterior tubercles of thetransverse processes of the fifth and sixth cervical vertebræ.* The "vertical portion" arises, below, from the front of the bodies of the upper three thoracic and lower three cervical vertebræ, and is inserted into the front of the bodies of the second, third, and fourth cervical vertebræ.
Clinical significance
It is commonly injured in rear end whiplash injuries, usually resulting from a
car crash .This muscle is in front of the spine and is thought by some scientists that it may cause some whiplash patients to have an unnatural lack of curvature in the patients' neck.
