Longissimus Cervicis

Description

Running along the posterolateral cervical spine, the longissimus cervicis appears as a deep erector spinae column positioned lateral to spinalis and medial to iliocostalis. Its muscle belly and tendon slips track superiorly from upper thoracic transverse processes toward the transverse processes of C2 through C6, lying posterior to the cervical facet (zygapophysial) joints. Superficially, you would expect splenius cervicis and the more lateral levator scapulae to overlap this compartment, while the occipital bone and mandibular ramus frame the superior bony context in a lateral neck view. Orientation is clear. Longissimus cervicis matters because it is often implicated in extension-based neck pain and myofascial trigger points after whiplash, with referral patterns that can mimic cervicogenic headache and upper trapezius strain. For posterior cervical approaches, the surgeon must navigate layered paraspinal planes, and this muscle’s relationship to the transverse processes and facet capsules helps explain why aggressive retraction can contribute to postoperative axial neck pain. A lateral perspective also makes the functional line of pull easier to teach: ipsilateral cervical extension and lateral flexion, with fine segmental control across multiple vertebral levels. Use this artwork to support gross anatomy teaching on the deep back muscles of the neck, including differentiation of longissimus, iliocostalis, and spinalis in the erector spinae group, and to anchor discussions of cervical biomechanics in kinesiology and physical therapy curricula. It also fits well in spine-focused chapters for orthopedic, neurosurgical, and pain medicine texts where posterior cervical muscle-sparing techniques and sources of facet-mediated pain are discussed.
