M. longus colli
This muscle is frequently injured in whiplash injuries, which is sometimes also the cause of the incorrect lordosis of the cervical spine that often follows.
Origin: The three parts of the muscle differ in their insertion and origin:
- Pars obliqua superior: anterior tuberosity of the transverse processes of HW 3-5
- Pars recta: anterior sides of HWK 5-7 and anterior sides of BWK 1-3
- Pars obliqua inferior: anterior sides of BWK 1 to 3
Approach:
- Pars obliqua: anterior tubercle of the atlas
- Pars recta: anterior sides of HWK 2-4
- Pars obliqua:Anterior tuberosity of the transverse processes of HW 5 and 6
Antagonists:
Movement: unilaterally innervated: Lateral flexion and rotation of the cervical spine to the ipsilateral side; bilateral: Flexion of the cervical spine
