Anatomical terms of muscle

The Longus colli muscle is a muscle of the human body.

The Longus colli is situated on the anterior surface of the vertebral column, between the atlas and the third thoracic 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 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 the transverse 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.
