The musculus longus colli , also called musculus longus cervicis (from Latin musculus "muscle", longus "lang", collum "neck" or Greek kerbikárion "head holder "), in German long neck muscle , is a striated muscle ( skeletal muscle ), which runs on the ventral part of the cervical spine between the first cervical vertebra (the atlas ) and the third thoracic vertebra. The muscle can be divided into three parts:
- Pars obliqua superior musculi longi colli : origin of the anterior tuberosity of the transverse processes of the cervical vertebrae 3 to 5, insertion of the anterior tuberosity of the atlas
- Pars recta musculi longi colli (lies between the other two parts); Origin of the fronts of the cervical vertebrae 5 to 7 and fronts of the thoracic vertebrae 1 to 3, attachment of the fronts of the cervical vertebrae 2 to 4
- Pars obliqua inferior musculi longi colli : origin anteriorly of the thoracic vertebrae 1 to 3, insertion tubercula anteriora of the transverse processes of the cervical vertebrae 5 and 6.
The blood supply is via the artery cervical ascending , vertebral artery , deep cervical artery and artery intercostal suprema .
function
The longus colli muscle, isolated on one side, causes flexion to the side of the active muscle and rotation (twisting) of the cervical spine when it contracts . With bilateral contraction it leads to a ventral flexion (bending forward) of the cervical spine.
Clinical significance
The muscle is often injured by whiplash injuries, most of which are caused by car accidents.
Some scientists attribute the faulty lordosis in whiplash patients to injuries to this muscle.
