Oblique x ray of cervical spine4/9/2024 ![]() The vertebral artery traverses the anterior portion of the cervical neural foramen at the vertebral body level, the vertebral artery courses through the transverse foramen. The cervical neural foramen contains a ventral nerve root, the dorsal root ganglion, foraminal veins, and a small amount of fat. The cervical neural foramen is located anterior to the cervical articular pillars and superior articular process and is bounded anteromedially by the uncinate process (see Fig. ![]() The lateral arch of C2 is very unique because it is in reality an elongated articular pillar that embodies both the C2 pedicle and C2 pars interarticularis. The superior articular facet of C2 is nearly horizontally oriented and is positioned relatively far forward and superior to the inferior articular process of C2. The lateral atlantoaxial joint, that is, the C1-2 facet joint, is positioned more anteriorly than the cervical facets below the C1-2 level (see Fig. The C2 vertebra is unique because of the odontoid process but also because the lateral arch of C2 anatomically is like no other vertebra. The degree of orientation of the cervical facet joints in the oblique coronal plane varies according to the cervical level (see Fig. The cervical facets are oriented in an oblique coronal plane, which helps prevent translation of the cervical vertebrae along the anteroposterior axis ( Figs. The cervical facet (zygapophyseal) joints are true diarthrodial joints, containing synovial fluid and lined by hyaline cartilage ( Fig.
