Sagittal section through the lateral
portion of the articular pillar of a normal midcervical spine. The
articular masses, composed of superior and inferior articular
processes and a virtual pars interarticularis, are roughly rhomboid
and carry obliquely sloping articular facets dorso–superiorly and
ventro–inferiorly. Circumferentially meniscoid synoviat folds (tags)
project into the zygapophyseal or facet joints. Anterior to the
upper articular process deep notches accommodate the root sleeve,
ganglion portion of the root and the postganglionic cervical spinal
nerve. This section also displays the vertebral artery (black) in
the transverse foramina of the vertebrae. Anteriorly the artery is
bounded by the thin bony shell of the rib antage portion of the
composite transverse process. |
